the car smoked big time. I finally realized the dipstick kept coming out. Replaced with a new one and hasn't happened since. However that was about 6mos. ago and now after adding the JWT Dual-POP and 555 inj. with the low speed stall hose, I have noticed alot of smoke again and only when I back off boost. Gonna have to investigate this again and see what is going on. I am running currently old stock turbos. I might go ahead and change the PCV's as well.
