is my engine blown ?

[thilaksharma]

i drive a car with 4g63t VR4 , equivalent to the 1g
t04e turbo , 560cc injectors , standalone ecu.

recently i had a overboost , everysince then i have white smoke from my exhaust
i noticed oil leak from the turbine housing and also the compressor housing
i sent the turbo to get it repaired , replaced all the bearings , bush and seals
got my turbo back , plugged it in, and still i get white smoke.
and i opened my intercooler and found that there is sooo much of oil in it, its just dripping oil. bout 50ml of oil.

i did a compression check i got my results
dry test : 100 100 80 100
wet test : 160 170 110 160

guys, what can u assume from this.

i did not have time to go under the car yet, but i suspect the oil return line for the turbo is clogged up , what else can it be ? is the compression diffrence so much to conclude that it is a blown piston , or is it a worn piston ring

White smoke is generally coolant. Sounds like a blown head gasket to me. This could also make your compression numbers off. As far as the oil in the intercooler that is more than likely from the turbo when it was blown. With the bad seals it was pushing oil out the j-pipe to the LICP and circulating it through the intercooler system. So I am pretty sure your motor is ok. Just a blown head gasket.

I agree. Blown head gasket. White smoke usually means coolant. I don't think the oil return line is clogged, but I would chech anyway, it couldn't hurt.

but the thing is that i do not use COOLANT at all
i am on plain water because denso has a warranty void for my new radiator if i used any coolant
