Road trip blues - davidkerryedwards - 06-26-2006 10:15 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.

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.

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.

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.

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.

( 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.

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.

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.
