This roadtrip is turning into a sequence of mechanical problems. After we got
the idler
pulley repaired in MO, we made it to WV when the crossover pipe (a second rate
flexible
pipe) failed. FMCA road service sent out a mechanic who removed the broken end
and re
attached it. We got down the road 40 miles and it failed again,. I reattached
it myself and
we limped into Cumberland MD on Saturday where we waited until this morning(in a
shopping mall parking lot) for an exhaust shop to open. Jim's transmissionn and
exhaust
did an excellent quick job and we were on the road by 11am. A mile down the
road the
engine quit suddenly at 60mph. Pulled over, restarted it and set off again.
this happened
three times in 5 miles. I called FMCA road service again since it was dangerous
to drive
since we lost power steering when the engine quit. Were towed to Keyser WV
($431--buy
road service!) where we are currently in a motel. The current diagnosis is that
when the
crossover pipe failed it sooted up the air cleaner resulting in very high vacuum
in the
intake which sucked down a rubber hose cutting off all air flow to the engine
and shutting
it down. We're waiting for a new air filter to arrive by UPS tomorrow. I had
thought the
turbo was failing and seizing up, so if this diagnosis is correct, it's a much
more simple
fix. The diagnosis makes a fair amount of sense since the shut down problems
occured
after the crossover pipe was properly fixed with a solid pipe which would make
the turbo
operate more efficiently than the loosely attached prior repair.
We hope to make it to DC sometime this summer and then have a less eventful
journey up
to NYC, Montreal, and back to Denver.
If anyone has any better diagnoses, jump in. The air filter is within a couple
of feet of the
ccrossover pipe and it was completely black when removed. Apart from a turbo
failing, I
can't think of any other explanation. It definitely had fuel since the max fuel
light was on
when it happened and it shot out lots of gray smoke upon start up. The only
other thing
that could seem to cause a diesel to stop running is lack of compression, lack
of timing, or
lack of air.

Crossover pipe takes the exhaust from one manifold over to join up with the
exhaust from
the other. In my case it takes the right exhaust over to the left side where
both power the
turbo. It broke on the left side right near the intake for the air cleaner
which is in front of
the left wheel. I had to drive it a couple of miles to an exit and it was
spewing huge clouds
of black smoke because the turbo was barely turning since the exhaust from both
sides
was following the path of least resistance which was out of the broken pipe
instead of thru
the turbo. Without the turbo'd air it was way overfueled for the amount of air
it was
getting.
By the way, it is probably worth noting that the crossover pipe had probably
cracked
before it broke resulting in less air and I had noticed the egt's were running
about 150
degrees hotter than normal. They could get over 1200 degrees if I wasn't
careful on a
steep hill. This tells me a richer or overfueled engine could have dangerous
EGT levels
pretty easily.

I think if it was an air issue you would see major black smoke out
the pipe. Why don't you run a 12 GA wire from a hot spot directly to
the Fuel shutoff (past the cockpit for removal on shut down). This
will rule out the fs power but not the FS solenoid.
If I was in MD waiting for UPS My bus would be towed bayside with
crab traps tied to the bumper and with in reach of Silverqueen corn
and Md cantaloupe

I thought about the solenoid last night. I wasn't looking at the exhaust when
it shut down
but one time the max fuel light was on when it happened. However, it put out
clouds of
grey smoke when I started it up each time, which seems to indicate there was a
lot of fuel
in the engine. I'll buy a coil of wire this morning to try this out should the
air filter not
solve it. It is certainly acting as if I turned the key off.
As far as the general issue of putting o ut a lot of black smoke with a plugged
air filter, I
think the theory is that since the engine is turbocharged, the sucking effect of
the turbo is
overcoming the plugged filter to some degree, pulling thru a decent amount of
air until its
power collapses a rubber hose section of the air delivery pipe. Lucky for me (I
think), the
shop where it now sits had another truck come thru there this spring with
precisely the
same problem caused by a small underhood exhaust leak sooting up the air filter.

Chris:
I think it might be a good idea to start a data file which reported what
mechanical failures
have happened to forum members when on the road. It might show a pattern from
which
we could learn. In my case, I was not aware of any issues with the idler pulley
before we
left home. I had looked at the crossover pipe and thought a flexible pipe was
inappropriate and put it on the back burner for replacement. There was no
indication it
was about to fail, I just didn't like the idea of flexible pipe. I assumed the
cat dealer
installed it when the engine was replaced so I was also deferring to their
judgment.
The 3208 CAT service manual does provide recommended routine replacement times
for
various parts to avoid inconvenient failures. I'll have to check on the idler
pulley lifespan.
In may case, I'm not entirely sure what was replaced when a reman'd engine was
installed
25k ago.

Kerry, The Flexpipe you are talking about runs from engine part to
engine part and a solid pipe woud do. ( I am sure you know, just
wanted to point out to others) There is a need for flex pipe section
in the exhaust system between the bushing mounted diesel engine and
the solid frame mounted tail and stack pipes. the flex section
takes up the engine torque roll and frame twist and keeps the
manifolds, pipes and brackets from tweeking and cracking
I kept snapping pipes on a truck untill it was found that the flex
section was parallel to the torque roll and would not provide any
give. I added a flex on a section that was on an angle to the engine
axis to correct the problem.

Yes, that piece of flex is important, although the 3208 does not
shake rattle and roll as much as the 5 cylinder in my Mercedes. I
think when the new engine was installed, the installer used flex
pipe because he didn't have access to an exhaust pipe bender.
Still waiting for the air filter to be delivered and it does not
look promising today. However, we are seeing places we had never
planned to see. We even saw the Great Race arrive in Cumberland on
Sunday. Very cool group of old cars.

Keep in mind Kerry has an aftermarket turbo conversion applied to a NA 210 hp.
I suspect there is a fair bit of "custom" work done to the coach that
complicates maintenance issues when they arise.
Fresh properly adjusted belts,new hoses, proper cooling system ph level and a
clean fuel system are the best ways to stay off the side of the road.

the other. In my case it takes the right exhaust over to the left side where
both power the
turbo. It broke on the left side right near the intake for the air cleaner
which is in front of
the left wheel. I had to drive it a couple of miles to an exit and it was
spewing huge clouds
of black smoke because the turbo was barely turning since the exhaust from
both sides
was following the path of least resistance which was out of the broken pipe
instead of thru
the turbo. Without the turbo'd air it was way overfueled for the amount of air
it was
getting.
By the way, it is probably worth noting that the crossover pipe had probably
cracked
before it broke resulting in less air and I had noticed the egt's were running
about 150
degrees hotter than normal. They could get over 1200 degrees if I wasn't
careful on a
steep hill. This tells me a richer or overfueled engine could have dangerous
EGT levels
pretty easily.
