white smoke after I release the throttle

[HVAC SuperTech]

Hey everyone. I noticed today while driving, that I had a bit more white smoke out of my tail pipe than usual. Its usually more at idle, but sometimes when I jump on the throttle, it starts out white, goes to grey quickly, and then BLACK. I know the blacks good, and so is grey. I was wondering, my truck has 257K on it, and maybe the FPR spring is weak? and causing the FP to be low? I checked it before and I was sitting at 48 PSI when I nailed it. My turbo is going south, and it makes a very high pitch whistle or noise when I really push the truck. I am in need of a rebuild and I did see some oil comming from the 2 halves of the turbo, next to the pedistal mounting bolts. I smell oil in the exhaust pipe too. so I am assuming that most of the smoke is comming from the turbo spitting the oil. Am I correct? I am gonna do the BB on the FPR spring tommorow and see if it helps.

Might want to consider a compression test. Could be coolant leaking into the cylinders or worn rings.

ok, I aalso trying to remember a test someone told me. Something about having the truck warmed up real good, and removing something on the air intake hoses, and taking the oil filler cap off to see if I had blow by or something? You know of this test Vital?

I notice I am losing a small amount of coolant somewhere, but I saw that I did have a leak next to the t-stat housing. replaced the fatory spring clamp with a wormgear and it fixed the leak.....

Think I should still try the BB mod? or not worth the time?

[vitalidle]

Yeah but your supposed to have special cap with an orfice and a gauge that reads inches of water. I don't know how you could tell other then pulling the oil fill cap and run it and see how much oil comes out or blows by.

[vitalidle]

I guess if it was me I would wait on the mods till you got it running right

[HVAC SuperTech]

yeah, I was thinking the white smoke could be a fuel delivery problem...heard of that too.

[vitalidle]

yeah but its usually blueish white or blue smoke if its a fuel starved. I would do a compression test just to make sure it can't hurt

Thanks man...I'll have that checked...
