A parallel case, from the world of computers (quoted from the
alt.sysadmin.recovery USENET group):

   So I'm waiting around after hours here at BFC, because we've got a bad
   4mm DAT drive attached to the file server in our lab, and the daily and
   weekly backups are therefore suspect. Also the disk drives are making
   that sound which says, "I'm a happy drive. I'm a cheerful drive. I'm
   smiling at you because I'm grinding my spindles into microscopic dust
   and there's not a single thing you can do about it. I'm going to fail.
   I'm going to do it soon. Or later. I'm not telling. Probably soon,
   because I've been chatting with the DAT drive two hops up the SCSI
   chain, and he tells me that he's been ill, so if I fail *now*, you'll
   have no recent backups. That's why I'm happy. I'm in control. I want a
   goat. And candles. Black ones. Pray, human.  Pray that I'm in a good
   mood. PRAY, DAMMIT, ON YOUR KNEES, YOU LIMACEOUS BIT OF MEATWARE!"
   
   I digress.

My solution is never to have one there in the first place. Any
bottleneck in your fuel system should be accessible and serviceable -
especially when you're at sea, in big waves (take my word for that
one...) From my perspective, a filter, or even a strainer, inside a fuel
tank is just plain bad design.

I recall a very experienced cruiser in another group writing up his
ideal tank setup: a large-diameter pickup that goes down to an
indentation in the bottom (yep, it _will_ collect crud. That's what you
want it to do so you can get it out!), with a Lexan access cover on the
side of the tank bolted over a Neoprene gasket so you can both see the
inside and clean out the tank whenever necessary. Add Norm's fuel system
to that, and you can't get any more reliable unless you go with an
electric drive. :)

Re: [Liveaboard] looking for tough engine diagnosis problem (andsolution)

2011-07-11 Thread SteveW
Similar scenario but at least in-shore on the L.I. Sound. I checked 
everything I could see, checked everything else, and was spitting nails by 
the time I limped into a marina on our route which promised a decent diesel 
mechanic. After I described the problem, he asked whether I checked all the 
various filters in the fuel system so of course I answered in the 
affirmative. When he asked about the one at the end of the pick-up tube 
inside the tank the look on my face must have been priceless. I didn't know 
there was one!!!

Fortunately this was on my old boat and the top of the tank was accessible 
with a minimum of bodily contortions. Sure enough, he pulled the tube and 
there was an entire bio-system living in/on that filter. Fifteen minutes 
later, a new filter installed, we fired her up and she ran like a purring 
kitten.

Argh! BTDT, still got the T-shirt. :) Windless passage from Mayaguana to
the Turks and Caicos; the engine runs fine up to 1850RPM, chokes and
dies within 2 minutes of going to 1900. Back off, runs fine.
Normal-seeming fuel flow all the way up to the HP pump... took most of a
day of this before the light in my brain went on.

Just before getting on the banks, I disconnected the fuel line and stuck
it into a 5-gallon diesel jug; used that to get into Sapodilla Bay, with
the engine running just fine. Then, with gritted teeth, I took apart
nearly the entire aft end of the boat I was on to get to the top of the
tank, pulled out the intake tube, and found what I just *knew* I would
find there: an intake filter, packed with algae and other kinds of
accumulated crap. I ranted about it for most of a week. "What kind of a

Someone once said that if you think it sounds like horses, you should
check out whether it is horses first before you go looking for zebras.
So the first thing to check is those things that would be the most

I understand that problem happens when the engine is run under a light
load and never gets to operating temp. Some folks run the engine once a
month at the dock for a short time, then shut it down thinking they are
doing something good. Turns out it is not so good. Battery charging and
refrigeration loads do the same thing. The engine never gets hot enough
to completely burn the fuel and it collects, layer upon layer until .. .

Re: [Liveaboard] looking for tough engine diagnosis problem(andsolution)

2011-07-11 Thread Hugh Barrass (hbarrass)
It seems like all the tough ones are fuel related...

(on a gasoline engine) I had a warped carburetor housing. Started OK,
ran for a long time. Sometimes stalled - never restarted while warm.
Solution - don't use gasoline engines :-)

I had one that was mysterious until I looked directly at the engine
while it was running. Slightly corroded blanking cap (I don't know the
proper word - it fills a hole that would otherwise have a connection
screwed in) in the cooling jacket of the engine. When it was cold or
running smoothly it was fine. Load the engine heavily it would overheat
for a while then settle down - seemingly at a higher running
temperature. When I looked at the engine running I saw a tiny jet of
steam coming out when I started running heavily, after a while it
stopped (I'm still not sure exactly why). Ease off the load & it
stopped. Simple (& cheap) to replace, then everything was OK.

Sailors miss out on all this fun!

Hugh.

Hi All,
I had a similar experience, and after all the angst and anger, and the help
of a really talented diesel man, learned it was a nearly plugged exhaust
water injection elbow.  Turns out that they accumulate soot that cakes onto
the inside, slowly building up until the back pressure builds to the point
the engine loses power and finally stops after a short time running.  It
will readily re-start, then stop again...and so on

Good luck.

Re: [Liveaboard] looking for tough engine diagnosis problem (and solution)

2011-07-11 Thread Alan Lewis

 I had a similar problem last year on my Perkins 4-108.  It was a dirty  
primary filter; now have a vacuum guage on the Racor to monitor flow.  

To check for air in the system, put the end of the fuel return-to-tank line in 
a jar of fuel and look for bubbles.  If none, that's likely not the problem.

Re: [Liveaboard] looking for tough engine diagnosis problem (andsolution)

From: "jim sims" 


Opening up the problem space a bit - ignore the original symptom list.
What is the toughest (engine) diagnosis (and solution) you've had to
deal with?

Thanks a million!
capn jim


Took the words right out of my mouth - I'd thought the original exercise was 
to produce something tough, not solve a hypothetical question as posed by 
Jim...

Skip, no engine problems, cuz still on the hard, fairing the bottom
