I have a stock b20 turboed via a greddy kit. Its intercooled, running a zdyne gold, walbro pump, and 440 injectors. I run it at 10 psi and barely ever go over 6k rpms.

However it has started smoking oil. It started only when i would shift, now its especially bad when i let off of teh pedal.

I yanked the plugs and took some photos, does it look like a ring/valve problem to you? Or did i fubar the turbo possibly?
(if the photos do not work, please let me know)

Hard to tell by plugs alone. Do a compression test and tell us the results.

 

well it your Zdyne GOLD tunned?

I seem that your running a lot more richer than normal. Are you sure that it's a cloud of black smoke and not grayish/white?

Did you put too much oil in the motor, causing some oil to slip past the rings and enter the cc?

 

I would guess my tune for the zdyne is rather crude. I have never been able to find a reliable b20 tune. It has worked for a few months rather decently. I have built the tune off of a stock pr4 tune

Im confident that it is a blue smoke and it smells like oil. Im just wondering if its the turbo.

 

i would say an easy way to test if its the turbo could be to take off the downpipe and see if there is oil, or oil residue, thats what i had to do for mine

 

Did compression check and #1 and #3 = 185. #2 and #4 = 195. What does that tell me? Should i look into the turbo?

 

yeah i would, those are the exact signs i had, like i said take off the down pipe, you can tell FOR SURE that if there is oil in that area, it is definately your turbo

 

The pictures dont work for me.... Take off the DP and see if there is oil residue...

so did you take off the downpipe or find anything else out???
got an update???
