Tough recovery

[Mark3395]

Picked up a deuce at Ft. Sheridan and got it exactly out of the motor pool before it ran out of fuel. Jump at the batteries didn't work so I plugged a couple screwdrivers into the slave cable recepticle to jump it. Fuel leaks,rain, no driver's window latch, onset of dark, Chicago area traffic in the rain, and did I mention rain?

But the truck ran like a striped-assed ape dragging 13,000 lbs. 80 miles down the road in the rain (did I mention that?) heard a screech that sounded like a belt slipping.

50 miles further the truck started smoking badly but it was made more comfortable by the turbo whiine, which disappeared. Looked like an M60 laying smoke.

Thought that the injector tips might have been damaged by water from the rain, but the cap was on just fine. Don't figure that started the smoking.

Am thinking the turbo froze up and choked off the supply of air. Does that make sense?

It's stopped raining for now. Think I'll salvage a turbo from a parts truck.

If the turbo fails, it will smoke a LOT. Lets see... I lost one on a Detroit engine once & it used a couple of gallons of engine oil, in just a couple of miles. The lube oil for the turbo went into the air intake manifold - so it burned that too. They don't have seals, but close tolerance bushings. When they go, lube spills, usually, into the intake side, due to the negative pressure. That is the good part. The impeller can shave metal from the snail housing, or worse, loose vanes from the impeller that can cause a sever digestive upset!

Hope your worst experience was the rain.

If you heard "the squeel" then that turbo is junk.That was the sound of aluminum impellers grinding on the housing at 100,000rpm.Only thing saveable is the center section now.
