It will also quiet down more and run smoother after you have proper injection on all cylinders for a while -- the pre-chamber will carbon up badly when the injectors don't fire properly. This will burn off with driving. Peter On Apr 25, 2011, at 6:46 PM, Tim C wrote: Two business days later the significant line was waiting when I got home.

Re: [MBZ] OM603/300SDL startup noise
This afternoon (another warm day!) it got a lot worse all at once, and just now I caught it in the act: one of the delivery valve holders (#3 from front) is spurting fuel. Seeing it reminded me that it was repaired by the PO using silicon tape, and since it was working I'd forgotten it.

Re: [MBZ] OM603/300SDL startup noise
Okay, I need to break this down. I looked in the EPC but I have no idea what I am seeing. I have never messed with an IP so I'd be happy for pointers. :) I pulled the DV cover open at work, scraped all the old silicon tape out. The little metal ring that sits on top of the line is obviously cracked; I assume that is supposed to be like a washer, pushing down the cover of the fuel line, which then (correctly) sits in its little cone in the DV. I don't see how I can get the fuel line apart to replace the little washer. To make the car work this evening, I put on some new silicon tape. I also tried using one of my oil washers, but while it fit it didn't seem to do anything useful, so I took it out lest it decompose into the IP. Will pull out the silicon tape since it's not helping much, if any; had to two-foot high idle it all the way home. To make the car work tomorrow, what can I pick up today? Anything? [Or is that, go outside and fix the 300D... :] Will new o-rings and copper seals fix the fuel line leak? I thought that was for below the DV. Or does that make it not run the fuel up?

Re: [MBZ] OM603/300SDL startup noise
1. Have you changed the little orings on the stem (center bolt) of the oil filter lid recently? 2. Could be the chain tensioner is letting go. If so, the chain probably it tired too. 3. I thought about an injector nailing, but your description sounds like it is all cylinders. 4. Could be compressor/clutch but that usually would not quit after startup 5. Could be starter, but that is a high speed whine. I started the '87 300SDL with the #22 head 7 times after noon today. Four of the times, there was a distinct loudness for a second or two after start. The first time I was at the fuel station, and it literally sounded like a big truck started right next to me. At first I thought it was just an echo, but then it went away. I guessed maybe it was the AC compressor (first warm day, doesn't work anyhow), but I flipped the climate control to EC after lunch and still heard it.

Re: [MBZ] OM603/300SDL startup noise
Forgot to add, that in the case of #2, the tensioner loosing oil pressure, refer to #1: Change the two orings on the oil filter cover stem.

I guess the chain could skip a tooth and I would see lost power; could it skip a few teeth at once and thrash valves? Mainly looking to know if I am likely to get warning before I hear crunching. I'll try to get someone to help start it at lunchtime, maybe I can get a better idea of where the sound is. Thanks everyone! -Tim crossing fingers for the oil rings 3.

Re: [MBZ] OM603/300SDL startup noise
Could be something simple? - like motor mounts got squished or engine assembly is not settled in to running position? Normal motor sounds are being amplified through the body as a result of diminished dampening from motor mounts and other noise dampening mechanisms? mao ___ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

Re: [MBZ] OM603/300SDL startup noise
- Might the starter not be disengaging? Is that really a failure mode for a 603, and how would I be able to tell if that was it? Ours did that once, but I wasn't there. (Wife was.) It wouldn't stop, and started smoking before it finally released itself. It got a new starter shortly thereafter.
