Thread: blown turbo?

Hey guys got an issue with my 1993 sentra that has an avenir in it.
I bought it and the kid said the turbo seals were blown. At idle it's fine and doesn't smoke , light driving fine doesn't smoke. When getting into boost it holds boost but when you decelerate or some to a stop it smokes alot and it's a blueish white and smells like burning oil.

I purchased a used t25 and swapped it out but I'm having the same issues.

Is it possible both turbos are blown?

Could the oil be leaking somehwere else ?
What's the best way to diagnose this issue?

Check pcv valve & make sure none of your lines/hoses are kinked. Mine smoked once coming to a stop when the line off the IC to the crankcase was kinked.

B

Pcv valve seemed good. The oem catch can is deleted and the hose going between there now seems kinked. I wonder if that could do it ?

Blown oil ring on the turbo will smoke as oil pressure goes up. The higher the RPM the worse it should get.

The car isn't on the road so it's hard to test drive it. But when I go into boost it doesn't really smoke. If I go from one stop sign to next and get in it and stop at the 2nd stop sign I'll have a big cloud of smoke

@blkb13 give this a read

2nd one is of reving it and letting it go . (Car was fully warm at this point)

I change new turbo and still smoked found out my oil return hose looked like a z shape instead on an s smooth shape fixed put new hose and Smooth it out 0 smoke after that!

I'll double check that but if I recall correctly the return was fine and straight. And all the o ttr her lines are hard lines
