We've been careful to follow the 5 minute idle regimen on start/stop but who knows what was done before we got it. Thanks for the good info; it really makes sense. I'll check it out and report back.

Believe I do - haven't used it in a while. If push comes to shove I can always improvise. Could that be a source of oil coming past the seal on the exhaust side? If it turns out the turbo needs work is it reasonable to have it done or just toss it? I watched it the other day after shut down...

Ken, As I recall there was no end play on the turbine shaft, but I'll check it again when I get the time. Put Dad in the hosp. with CHF at age 97 so things are a bit busy right now. Still need to follow up on Bjorn's suggestion of checking the flame heater. Thanks for the help.

Good idea (s). I'll check out the flame heater today. I've never switched it on so it shouldn't be leaking but wierdness seems to be the order... I guess at this point about all that's left is pump timing and the pump itself. All this would be much easier if I were getting black smoke!

Currently, the Master Cylinder vent is disconnected from the MC cap. There is what appears to be a vent tube that tees into the road draft tube (crankcase vent); is that what you're referring to?

OK, took the air intake off the turbo and verified the wheel will turn freely. Cranked 'er up and the turbo is spinning. Shut 'er down and watched the turbo coast to a stop. At idle everything is fine - just a wisp of thin blue smoke as it warms up. AT 1100 RPM throttle setting oil is...

Filter was/is clean as we replaced it just to be sure. Also ran the engine with the intake disconnected from the turbo inlet - no change. Have not watched the vanes turn while running yet but have turned the air side manually. Turns smooth but has some drag sort of like tight seals. Will not...

OK, I sent the injectors to the shop for cleaning/testing and checked the compression while they out; 500 lbs +/- 10 on all cylinders. Other than a thin bit of light blue oil smoke, the engine does not smoke at any RPM UNTIL you hit the throttle. The size of the grey/white smoke cloud is...

Thanks Will, I'll try those this evening. I just got the nozzles back from the shop so hopefully the pintle is not an issue. Bled air out of the secondary filter bleed with engine running - can't see bubbles in the nozzle bleed return line anymore. Lift pump seems to be ok but haven't...

I guess I'm having trouble getting my gasoline mind around diesel concepts! Since there is no throttle plate, manifold pressure is essentially ambient pressure. When you add a Turbo you are boosting ambient to some positive pressure. Seems like the higher the engine RPM, the more exhaust flow...

There's no white smoke at any throttle setting, just on rapid acceleration (a blip on the throttle will do it). Coolant is clear, no bubbles. Oil OK. Still wondering about the boost pressure - Shouldn't there be at least a few psi on the intake manifold at idle and go up with RPM? The smoke...

I know this has been addressed somewhere not too long ago but danged if I can find it! Been chasing down the source of slobbering and HUGE clouds of white smoke on acceleration - the harder the acceleration, the larger the cloud! Had fuel injectors cleaned, set etc. - no change...
