[Chevelle-list] Timing Question
Hi Again Guys I was wondering if anybody has had this happen. I wanted to give my timing alittle more adjustment as the advance cannister was hitting the intake manifold at 8 degrees BTDC when you turned the distributor...I made my marks on the distributor and lifted it to turn it one tooth on the cam gear Now the engine doesn't run very well at the 8 degree mark but runs really well at the 40 degree BTDC mark(it took me awhile to find this out as I kept advancing till things smoothed out)Any Ideas John
Re: [Chevelle-list] Timing...
John- Depending on how big you’ve gone on your cam it can help considerably. Advancing your initial timing will also create more vacuum and make your carb more responsive. Time it by ear and see if it doesn’t end up a few degrees more than stock. I wouldn’t be surprised to see 12-14 degrees initial. My race BB likes 18-20, but I wouldn’t suggest that for a starting point. When it is right your idle will smooth out somewhat due to increased vacuum, and it won’t diesel when turned off. It should also restart immediately without having to provide any fuel from the gas pedal. Hope this helps.

Re: [Chevelle-list] Timing cover pan gasket
thanx Mike..I'll try that...I fired the engine up again yesterday to see exactly where the leak was coming from and found that it had slowed down to about 1/4 or even less than it was initially..Hopefully i will get this solved without a major tear down.. John 66 Malibu
Re: [Chevelle-list] Timing cover pan gasket
John, Sorry, I didn't notice if anyone replied or not, so I'll take a stab at it anyway. Yes, you can replace the TC gasket by lowering the oil pan. It's a pain, but can be done. The hard part is getting the pan gasket to seal properly afterwards. I've done this successfully; one single time in my life, but might work, if you don't mind the look. Take some brake cleaner and spray the TC gasket thoroughly. Try to get all the oil out. Let it dry for a few minutes. Take your handy-dandy self-reproducing nasty old Ultra-Black silicon, and fill up the outer edges of the TC where it leaks. Smooth it over with your finger for that "almost hilllbilly" look.I successfully sealed up a front seal on the bottom side of a TC like that once. Fortunately, no one could see the work of art that silicone provides.But it worked, no more leak! and only took a few minutes of effort. However, I've tried a couple of times since then with less success. There's also some other products similar to silicone that advertise 'instant seal' even with oil present to seal up similar oil leaks. Find them near the silicone in your local auto parts store. Good luck, Mike -- I would rather live my life as if there is a God, and die to find out there isn't, Than live my life as if there isn't, And die to find out there is. -Blaise Pascal Check out my webpage at http://www.ProStreetCar.com TREMEC Distributor at http://www.5speedTransmissions.com Team Chevelle member #1778 (Gold), ACES member #1377 Hoosier State Chevelle Assoc (http://www.IndianaChevelles.com) #6 Johnny Palmer wrote: Hi guys...Does anyone have any tips on fixing a leak on the timing cover oil pan gasket on a small block???..Can the oil pan be lowered enough with the engine in the car to replace it??

Great...so you didn't have to remove the timing cover at all even??I just did a cam change and was lucky enough that the leak isn't that bad that I couldn't do the proper breakin time..but I bet I lost a quart in 1/2 an hour..I just kept adding a bit in the vale cover as some leaked out... John
Re: [Chevelle-list] Timing cover pan gasket
John: I just replaced one on a 350 engine we built. I took all the pan bolts out,and it allowed the pan to drop about 1 inch to 1 1/2 in front. I then put the new gasket in and put the bolts back in starting at the front and working to the back. I had a chrome housing the had a small bend in it to the outside and caused mine to leak.Hope this helps Bob 64 SS ---Original Message--- From: The Chevelle Mailing List Date: 01/31/07 21:51:50 To: The Chevelle Mailing List Subject: [Chevelle-list] Timing cover pan gasket Hi guys...Does anyone have any tips on fixing a leak on the timing cover oil pan gasket on a small block???..Can the oil pan be lowered enough with the engine in the car to replace it??

Re: [Chevelle-list] Timing?
Check your vacuum advance. It may be hanging up. There should be a little rubber sleeve over the portion that hooks into breaker plate. I had a 400 that this rubber tube deteriated in and the car would run very erratic. Drove me crazy until I found the problem. Replaced vacuum advance unit, problem gone. gm66 --- [EMAIL PROTECTED] wrote: From: "Jim H. Thompson" <[EMAIL PROTECTED]> To: "The Chevelle Mailing List" Subject: Re: [Chevelle-list] Timing?

Re: [Chevelle-list] Timing?
Pelle,I got a response from Craig who co-authored the Watson Guides, and he had this to say:As long as the centrifugal advance isn't adding any advance at your idle speed, its not necessary. I've seen stock distributors add centrifugal advance at a very low rpm and cause you to not get the initial timing set where you thought it was. Then you'd drop it in gear and the engine rpm would drop way down and/or die. Just kind of annoying. I wrote that article a few years ago and had actually forgotten that I suggested setting the timing in gear. I'll probably go back and change it to say to check the engine idle speed in gear after setting the timing to be sure it still has sufficient idle speed in gear. Or something along those lines. I haven't set the timing with the car in gear for quite some time myself, so if I don't do it, I shouldn't recommend it to others. Thanks for the reminder!

Re: [Chevelle-list] Timing?*
That was going to be my point yesterday but no time to actually send the email. Using a timing light and at the same time, connecting a vacuum guage to the line that was connected to the vacuum advance, I set my timing for the vacuum signal. Rather, the highest or close the the highest vacuum at the same time noting the timing number. You can also advance the timing a bit further to a point where the vacuum begins to decrease and still be ok. That is the extent of my skills. I always wanted one of the Timing Lights that have the dial back to actually fully understand the curve and max advance. Hope this helps.

Krister, I run my car at 12BTDC. This is where it likes to run. Just like the book says, unhook the vacuum and plug the line that goes to the carb, set it at 8-10-12 what ever it likes the best. But you need to hook the vacuum back up and test drive it to determine where it likes it the best. If it runs good, no detonation it's where it need to be. I know my car don't give a hoot what the book say's, it just knows what it likes. Rocky = A Man And His Chevelle, It's A Beautiful Thing!!

Re: [Chevelle-list] Timing?
Now for the questions: does 10 degrees BTDC seem reasonable? Yep Any pros and cons for running here or perhaps 12 degrees BTDC. Nope-as long as it doesn't ping. Advance the timing 2 degrees at a time & test drive it until it pings. Back it down 2~4 degrees and drive it, you won't have a problem & will probably get better power & mileage too. BL
RE: [Chevelle-list] Timing?
The outer ring on your harmonic balancer is more than likely not in the position it used to be in. The rubber gets old and the outer ring moves. After that your timing marks are no longer accurate. I have found that used balancers usually aren't any better than the one you are replacing.

RE: [Chevelle-list] timing question (yes, another one...) PROBLEM SOLVED
Hi Jim, Another thing you might want to look into (if you have an HEI) is an adjustable timing control from MSD, part #8682. I just installed one on the Elky and it's great. There's only three wires that tap into the HEI wires, a small control box that needs to be mounted (mine's under the dash) and the adjustment knob (mounted mine on the side of the driver's seat). Now I can adjust my timing up to 15 degrees while I'm driving. If I ever have to use low octane gas I just back off the timing until the pinging stops. It cost $142.95 from Summit and took about an hour to install. Herb Lumpp http://users.adelphia.net/~hlump/index.htm -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of J.

Re: [Chevelle-list] timing question (yes, another one...)
Jim, along with what Bill said you might want to consider an adjustable vacuum advance canister. Before you start changing the timing, disconnect and plug the vacuum advance supply hose and go for a drive. If the pinging is still there you'll want to adjust the mechanical advance (loosen clamp and rotate distributor) but if it's not there a canister that gives you less advance than your current one may be the answer.

Re: [Chevelle-list] timing question (yes, another one...)
nice job BL - Original Message - From: Bill Lessenberry To: The Chevelle Mailing List Sent: Friday, April 30, 2004 5:47 PM Subject: Re: [Chevelle-list] timing question (yes, another one...) I am trying to understand the whole concept of timingin generalThere are basically two types of timing on motors--1.Cam timing, which is the relationship between the cam lobes' opening and closing points and the crankshaft position. This is set when the motor is built, and cannot be changed without disassembly of the engine (usually) and, 2. Ignition timing, which is when the coil fires the spark to ignite the fuel in the cylinder. This is adjusted by twisting the distributor. The timing is measured by the marks on the crankshaft pulley in relation to the marks on the timing tab that is mounted on the timing chain cover on the driver's side of the motor. When the coil fires, it sends current down the spark plug wire that jumps the plug gap, creating a spark that burns the fuel. Since it takes a certain amount of time for the fuel to burn, we need to send the spark down before the piston reaches the top of it's stroke. However, if the spark is sent too soon (too far advanced), the piston is working against the pressure of the combustion and that causes a knocking sound and some loss of power. I have a timing light but am notentirely sure of where to hook it up on my EdelbrockPerformer 600 carb.You don't hook a timing light to the carb--there are different types of lights, but usually you will hook one wire to battery positive, the other to battery negative, and the sensor to #1 spark plug wire. On a Chevy, #1 cylinder is on the driver's side front. When it's hooked up, the light will flash when the coil fires the #1 spark plug. Before you use the light you will need to mark the crank pulley where the line is scribed on it with a paint color that will contrast with the pulley color. Also mark the timing tab with the same color paint at the place where you want to set the timing. The timing tab is marked with a 0 in the middle. The marks that are above the 0 are Before Top Dead Center (BTC), the marks below are After Top Dead Center (ATC). If you want the timing a 10 deg BTC, paint the 10 deg mark on the tab. Usually you will also need to take the vacuum hose off of the vacuum advance can on the distributor and plug the hose with a golf tee or a screw. Start the motor, and see where the marks are. If you marked 10 deg, the mark on the crank pulley and the timing tab should line up. If the mark on the crank is above the mark on the tab, the timing is advanced; loosen the distributor hold down bolt and turn the distributor clockwise until the marks line up. If the pulley mark is below the tab mark, the timing is retarded and you'll need to turn the distributor counter clockwise to adjust it. Can I just turn the distributorcounter-clockwise an 1/8" or so and see if that helps?Yep, but that will advance the timing, and that's not the way you need to go to stop pinging. Turning it clockwise will retard the timing. Also when retarding the timing, do I just loosen thebolt and turn the distributor slightly?Yep, retarding or advancing. Or do I haveto lift it out of its existing position with the camgear and drop it back in? Nope. I don't know why, but thetiming thing has always been a confusing topic to me.I hope I didn't confuse you even more. :-))BL
Re: [Chevelle-list] timing question (yes, another one...)
I am trying to understand the whole concept of timing in general There are basically two types of timing on motors--1.Cam timing, which is the relationship between the cam lobes' opening and closing points and the crankshaft position. This is set when the motor is built, and cannot be changed without disassembly of the engine (usually) and, 2. Ignition timing, which is when the coil fires the spark to ignite the fuel in the cylinder. This is adjusted by twisting the distributor. The timing is measured by the marks on the crankshaft pulley in relation to the marks on the timing tab that is mounted on the timing chain cover on the driver's side of the motor. When the coil fires, it sends current down the spark plug wire that jumps the plug gap, creating a spark that burns the fuel. Since it takes a certain amount of time for the fuel to burn, we need to send the spark down before the piston reaches the top of it's stroke. However, if the spark is sent too soon (too far advanced), the piston is working against the pressure of the combustion and that causes a knocking sound and some loss of power. I have a timing light but am not entirely sure of where to hook it up on my Edelbrock Performer 600 carb. You don't hook a timing light to the carb--there are different types of lights, but usually you will hook one wire to battery positive, the other to battery negative, and the sensor to #1 spark plug wire.

Can I just turn the distributor counter-clockwise an 1/8" or so and see if that helps? Yep, but that will advance the timing, and that's not the way you need to go to stop pinging. Turning it clockwise will retard the timing. Also when retarding the timing, do I just loosen the bolt and turn the distributor slightly? Yep, retarding or advancing.

Re: [Chevelle-list] timing questions
Also check the timing with the light after the vacuum is reconnected and let us know what it is .. could be something wrong with the mechanism in the distributor. I saw on one time that would retard the timing when vacuum was hooked up. Seems like I remember that something to do with the linkage inside the distributor was backwards or something to that effect. It was in a points distributor I believe. Ðäññÿ .. Wilsher Motor Sports

Re: [Chevelle-list] Timing Question
As others have said the engine will run but not nearly at its full potential. However, it would be worth the effort to verify that the timing mark on the balancer is at 0 when the engine's at TDC on #1 or #6, especially if the balancer's the 3-piece style. If the outer ring has slipped the 7 ATDC reading you're seeing isn't an indication of the true timing. How much do you know about the engine's history?

RE: [Chevelle-list] Timing Question
With the timing set to 7 degrees ATDC, you're not even starting the combustion process until the piston is starting to move down the cylinder. The motor should feel pretty lazy. If you suspect your light is bad, try another light first.

RE: [Chevelle-list] timing
Graham, you can probably start at anywhere from 6-10 degree BTDC. Setting the initial timing at TDC will be a little on the late side. The motor might feel a little sluggish on the bottom end. To measure the total timing, you'll need a timing tap on your balancer, or a dial-back timing light. -Dave -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Graham Wooden Sent: Monday, March 29, 2004 10:51 PM To: 'The Chevelle Mailing List' Subject: RE: [Chevelle-list] timing Thanks Mike.

Re: [Chevelle-list] timing chain
Dan You should use a gear puller. I've also heard that a good tap on a chisel in a few places will break it too. Then on the other side, you should also use a gear pusher to put the gear back on. Heavy pounding on the end of the crank can do damage. Bill Cross
RE: [Chevelle-list] timing chain
I've always been able to get them off using a crow bar and just prying around it on all sides it usually comes loose. Unless your planning to degree in the cam, I'd just put it in straight up. Even if you go to degree in a cam they say you should use a timing set that allows you to adjust the large cam gear, not the crank gear (according to the video I got with my Crane degree wheel). I've never had any problems setting it straight up. just my 2 cents... Happy New Year to everyone on the list!

RE: [Chevelle-List] Timing tab location
Title: Message
It is possible
that your dampener outer ting has slipped, or that your distributor is off, or
something like that. You'll have to check TDC the mechanical way to know
for sure where it really is. Once you know for sure that the engine is at
TDC, then you can set your timing tab and distributor and start from
there. As for heat, I agree that advancing the timing will make the engine
run hot.

Dan, The timing tab can be anywhere you want to
put it as long as you then usethat position to establish true TDC of
piston #1 on the dampener and markthe dampener accordingly. Factory
placement for both SB and BB chevys isdrivers side of the timing chain
cover (about 1:00 or 2:00). If you buy anaftermarket bolt on it will
use two bolts on the drivers side of the timingchain cover and when
bolted on should be real close (provided the mark onyour dampener is

RE: [Chevelle-List] Timing tab location
Could it be that you have a vacuum leak? Try spraying some carb cleaner around the manifold and carb base gasket and if the idle rises at any time, maybe that is the problem. Also, if you are at a higher altitude, you do need to set your timing ahead. I’ve heard 1/2 degree for every 1000 ft above sea level. Good luck.

Re: [Chevelle-List] Timing tab location
ok guys... I had a chrome Mr. Gasket version that is supposedly right for my car. I attached it in the position you guys are saying, which is the only position that makes any sense, looking at my motor... When I started the car, at idle, the timing mark was WY off... when shooting the timing light, the mark was showing up at about 12 o'clock on the damper... So I adjusted the distributor and brought the mark to between the 6 and 8 BTDC marks... The idle dropped down, so I bumped it back up a little...

RE: [Chevelle-List] Timing tab location
Title: Message Timing tag should be located in the same spot regardless of what the engine is from. Should be at about the 2:00 position and bolted to the timing cover or part of the cover. Just have to ensure you have the correct tab for the balancer. You can buy them just about anywhere (don't you just hate that phrase?) Mr. Gasket has 'em in three flavors for a small block: (1) 7" balancer up to 1977 - #4592; (2) 7" balancer 77 and up - #4600; (3) small block 8" balancer - #4593 and one for a big block 8" balancer #4594. They also make two adjustables for small block #4597 for 7" and 4598 for 8" and one big block #4599 for 8". I'm sure there are others, maybe someone even has one laying around they'd donate for postage ?

RE: [Chevelle-List] Timing tab question
The timing tab shows degrees of crank rotation. Timing specs refer to degrees of crankshaft rotation. When you install a pointer on the block and degree marks on the balancer you set the motor up at TDC and then line the pointer up at 0 degrees on the balancer.

Re: [Chevelle-List] Timing tab question
I had the same problem on a 350 in my Nova. What I did was bring #1 piston to TDC using a piston stop and then looking at where the timing mark is. I was off about 10 deg. because of an aftermarket timing tab. When I figured out where TDC was I applied a timing tape to the balancer. Be sure your on the compression stroke.

RE: [Chevelle-List] Timing Chain Help
Charles, you need to pull the balancer off. There’s no way around it. If you don’t have the tool, most parts stores these days will “loan” you the tool. You basically pay for it, keep it while you do the job, and return it for a full refund. I think a balancer puller is only about $20-$30 anyway. There are also balancer installation tools that make it much easier to put the balancer back on. (avoid using a hammer if at all possible!). This is one of those tools I usually loan from the auto parts store. A new timing chain should be available from just about anywhere. A timing chain for a small-block shouldn’t cost more than $30 locally, or $20 by mail-order. A double-roller chain is a good upgrade and usually only $10 more. Don;’t quote me on that, it’s been a hile since I bought one. But, they’re relatively cheap. The real bear of the job you’re doing is re-sealing the timing cover and oil pan. It’s a poor design the way they meet each other to form the front seal. Be patient, take your time, and have a bunch of RTV handy. -Dave -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of [EMAIL PROTECTED] Sent: Wednesday, May 28, 2003 11:16 AM To: [EMAIL PROTECTED] Subject: [Chevelle-List] Timing Chain Help Hello Listers...

Charles, If you have an Autozone or similar store nearby, you can rent the tools you need.
