Issue with sr20, white smoke/ oil smell from exhaust - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So I've been having some issues with my car, the main things you need to know are

-SR20DE rwd with a garrett m24 turbo, don't know what exact model
-s15 side mount intercooler
-air intake with pod filter
-past owner said upgraded hg
-turbo pushing 10psi, though im not sure, since theres no boost gauge -_-

so symptoms are lots of white smoke blowing from exhaust, oily smell from exhaust,grinding kind of noise(maybe the turbo).

video of it you should really watch - if you listen carefully theres a grinding kind of noise

be really helpful if you guys can tell me what is wrong.

Check inside one of the post-turbo intake pipes for an oily residue.

felt cold, didn't really smell like anything, though i don't actually remember that well about it. could try idling it again outside

rent a pressure tester for the radiator
perform a leakdown test
perform a compression test

that should get you started, narrows it down quite a bit.

other notes:
looks like an oem turbo to me.
Check to see if the water lines are hooked up to the turbo. If you notice there are no water lines, then you have solved your mystery (stock turbo without water lines is ruined quickly).

90% Sure that you turbo is toast, well the seals anyway. If its the factory T25 you can rebuild or buy a another one here.

You really need to do a compression test to be sure.

yeah I'll do some more testing and etc. Doesn't a blown turbo smoke more when idling and when driving not as much.
