Default need some help...any ideas?

the car is an 06sti with 17k on it. I took the car to th dealer at 12k because after a group drive it was smoking at start up the next day. I am not talkin a little smoke, but filled up my 3 car garage, driveway, and was goin down the sidewalk amount of smoke. The dealer said "no problem found." Am i surprised, hell yes i am am! At the time all i had was a tbe, cf driveshaft, and Cobb AP. I just installed my new set up, Frank50, pe 850 injectors, pump, aps cai, aps turbo inlet, aps dr525, and drove to the dyno...15 miles.When doing my aps inlet, you have to remove the pcv crossover pipe from the drivers side (left) head, oil poured out of it. Put the car on the dyno and the spark kept getting blown out half way through the tune. Pulled car off dyno drove home, on a safe map. Pulled plugs and corrected the gap, from .030 to .026. I also notice that my oil catch can has about 1/4" of oil in it, so remove it and run with out. Of course i reconnected the hoses to the appropriate places. 2 weeks later the tuner comes back to town and i get back on the rollers. The car is doing weird *****. Tuner can't get the timing to go past 12 degrees, should be able to handle 18-20 degress of timing, but the ecu keeps pulling timing after 12. Then a purge control nipple breaks off, the one on the front of the manifold..right next to the engine harness part that goes over the turbo inlet. So off the rollers it comes, again. Now the car is puking oil out of my bov (hks ssq). The car has had a half a tank of gas through it since the last oil change, (did right before 2nd trip to dyno,) and is low on oil. It is about 1/4 of the way between low and full on the dipstick...on the low side. The dealer has pretty much told me to pack sand, even though the problem occured before goin big. I have a total of 1 tank of gas through the car with the new set up. The car also does not run smooth sometimes, erratic idle and stumbling. Other times, smooth. I am gonna try and do a compression test today, but i gotta take my girl out for valentines dinner. Any help would be appreciated. Right about now, i wanna blow my head off... this sucks. I am leaning towards bad ring lands. what do you think?

If you're lucky: just broken ringland(s).

Based on the amount of time you've had said problem coupled with the fact that you hit it with a decent-sized turbo while it was crippled I'd say be ready for some fairly extensive valvetrain damage as well.

This is going to be pricey.

Sorry.

Oh, btw .. there is no cel on either. Usually it comes on with a misfire when something like this happens.

tell me about it... if it comes apart, i am going with new piston/ring set, clutch, cams, and getting the heads ported. I really don't want to spend the money right now, so the credit card might get some unwanted abuse.

I can't believe your tuner continued the tune with the motor so obviously hurt. Won't hold timing, rough idle, continuous misfires, puking oil...sheesh, how many "stop signals" does a guy need?

Yeah, this all sounds really familiar. Broken ring lands at the least.

I just talked to the dealer...they may be willing to do some kind of 1 time good will repair...or at least help with the repair, due to my sevice records and previous problem noted in my records. I wont find out till prolly next week, so i will update from that point

when on the dyno, it did not misfire and would idle just fine. he was just making sure that it wasn't the tune before he quit.

Oh, OK - just puking oil and wouldn't hold timing (because of there being more oil in the jug than fuel/air).

Regardless, if your dealer will pop for a new motor with the mods you already had on the car, you are one lucky guy. Our dealers around here? You breathe the words "ECU reflash" and it's all over. Let us know if they help you out. Mod friendly dealers are not easy to find.
