Not to make you paranoid, but I started getting mild smoking and did the high and low side catch can thing…then one innocent rip and it was shaking at the next light. I still don’t know exactly what happened, but I suspect cracked ring or bent rod. Piston top looks fine , no wall scoring either.
I woul suggest you borescope with a side camera and check cylinder bore for scores just in case.
Ok. As you all will recall, last summer, melted a piston. Got one from a low mile engine and popped it in. Cylinder itself was unharmed, inspected, etc. Since then, the car drives fine, gets into boost fine BUT (and not always), when going flat out and going into lets say 4th gear, I get a A LOT of oil smoke out the exhaust. This happened at the track once last year.
Flash forward to this year, car is now on a bigger turbo housing but the same setup. More than a few times now, going from a stop and going flat out, once I get high enough up in speeds (100+), I get a HUGE puff of oil smoke, like a lot. Took the car out last night to Morris to have my buddy sit in the car and log (and hopefully run 10s). Ran 11.3@123, way down on power. Huge puff of smoke. No knock. No codes. No hesitation. No timing issues. Everything looks fine. Car never smokes on startup, never smokes on decel, never smokes getting into boost...only when I'm flat out going triple digits.
Took the car over to
SRT41320 for a compression check. All within spec:1: 170
2: 165
3: 170 (this was the bad piston last year)
4: 175
We're gonna do a leak down test next week but if that comes back good....what do I check next? The turbo? Maybe the cartridge is bad? I'm gonna have the tune looked as well but not sure what in the tune would cause that kind of smoke and loss of power (unless the car is overboosting?)
Open to suggestions and thoughts.
If you get pressure in the crankcase, theoretically oil drain back will suffer. Could be you’re overloading the seals and burning it out the exhaust.
You could maybe put a boost/vac gauge on the block just to be sure?

I swapped out to the bigger housing in the Spring....Id hope they're fine but next on the list pending leak down.
How is your drain flange sealed to the turbo?
When the fab guy put my C10 together the first time he used too much RTV between the flange and the turbo and it closed off 1/2 of the drain port - oil would back up and push past the seals when on a long pull.

The Smoking Tire guys have become the absolute most annoying fucks in the automotive reviews world.
Doug DeMuro has gotten to be the most annoying auto person to me. I haven't watched one of his THIS reviews in a while now.
