Don't know if this will help, but i've taken a log of my OCV & AVCS activity... Here's the link: OCV & AVCS Log

If the link doesn't work please let me know and i'll try and host it elsewhere.

Got tuned this past saturday. CEL's came back, and left, and came back, and left again and came back again... This is getting incredably frustrating...

Found the source of my CEL's, turns out the guys at machineworldNY.com royally messed up my heads (cut the valves wrong, messed up the valve seats, glass beaded the heads, didn't remove all the glass beads), and a leak down showed pretty much all of my intake valves severely leaking.

I got the same issue, I hear it every once in a while.

I got the same crappy problem with the idle being choppy and stalling, but im going to search for any vacuum leaks that I may have, have a good idea of where it might be.

The weird thing is that I am also throwing timing codes and checked and even re-did my timing belt twice and all is good there. If cams have anything to do with then a tune is in order, even though I just start it from every once in a while since I am waiting on more parts to come in.

I had this issue....

(both codes at once) First removed the AVCS screens, CEL came back.

btw - I highly recommend buying new $2 copper gaskets if removing the AVCS screens as the old ones will be pretty deformed and may not seal properly.

Final fix - changed the oil to some fresh oil... good to go.

The best advice I can give...when the CEL comes on, get the codes pulled ASAP. If the codes are p0011 and p0021, change your oil and oil filter ASAP.

These codes popped up on me over the weekend. I seriously doubted the timing, as I just recently had the belt replaced, as well as the pulley kit (this was about 5,000 miles ago). I changed the oil and filter, and within about 25 miles of driving, the CEL cleared on it's own. I had been running Royal Purple, but after reading post after post about how that stuff is crap, and my recent experience, I have switched to Castrol EDGE (formerly Castrol Syntec). I plan on changing again after about 1,500 miles, just to get out any extra crap that may be in the car, and start new.

I've read several places where people have lost turbos and engines, and can't help but wonder how long they drove around with the CEL on and these codes. This is why I can't stress enough, get the codes pulled ASAP when the CEL comes on. AutoZone does it for free. I also found out my usual mechanic will also pull codes for me free of charge, as well as help me decipher what they mean.

07 STI threw these codes so I came here and started reading.

Just got back from deployment, the car had gone 6k miles w/o oil change so I ran to a sit in your car place and had it changed as soon as I found out. 3 weeks later the codes pop. After some reading I decide to change the oil and I find the drain plug 1/2 a turn loose and the oil filter on tight enough that it took 10 minutes and 2 busted knuckles to remove. It was around a quart low.

I cleared the codes with accessport (I use stage 1 car is unmodded otherwise) and they have not returned. problem is I am pretty sure the turbo is going out now. I drove it about 2 miles after oil change and warming it up and it had severely reduced boost and I can definately hear noises that I have never heard before. I am somewhat loathe to blame the oil change place totally since blown turbo's seem to be pretty common on '07.



I think at this point I am just going to have it towed into the dealership.

I've got the p0021 code as of right now, and I've had it for quite some time. I have removed the OCV filters and even replaced the driver's side AVCS solenoid with no luck. Pulled my timing covers off last night and the timing is dead on. I found a thread on the legacy forum of a guy with the same issue as me.

http://legacygt.com/forums/showthrea...em-131462.html

As far as oil goes, I run asmoil 5w-30 in the winter and 10w-30 in the summer and am not burning any oil at all. The car runs smoothly, no stalling, regular idling, perfect gas mileage and no loss in power. After reading that thread I think its time to pull that cam gear off and check to see if there are any issues.

I am at the final stage of my battle ... after 2 years of fighting and nearly 5 to 6K spent on repairs I can not shake the P0001 code from my subaru. I have had one of my cams replace, heads gaskets done, heads completely reworked, timing belt, new turbo, new oil control valves, all the technical service bulletins done, too many short interval oil changes to mention along with oil system cleanings. After all of that work the longest the code went away was for a month and is now back again in all it's crappy idle stalling glory.

The only option I can see now is simply pulling the engine and replacing it. Based on one of the other comments I will do a leak down test before scrapping the engine just to see if one of the shops did crappy work.

I have learned two things from all of this ... I will only run synthetic oil in turbo charged subarus and if the p0001 code shows up on any of my future vehicles I will get rid of the vehicle that very day.

I would not wish this code on my worst enemy.

How many times have the heads been decked? The guys at area1320 found the thickness of the head gasket plays a big roll in the appearance of this code, they found that heads that were decked once or more, although within spec, were still shaved down enough to cause this code. IIRC they fixed it by switching to thicker .045 gaskets and that cured the problem on an STi that was having trouble with this code.

Here's a link to the thread: http://forums.nasioc.com/forums/show....php?t=2115862

Thanks g00fy! The heads have only been decked once to my knowledge. Do you think a leak down test would show this head gasket issue? I am sending it down to the local subaru dealership to have the leakdown test done next week. Any other suggestions or information from anyone will gladly be taken.

I don't believe a leakdown test would show whether or not your having this specific gasket thickness issue, it seems it's one of those things where you just gotta give it a shot and hope for the best. But good luck with it man, I know how it feels to be plagued with problems, I've been having nothing but problems with my forester build for the past 3 years.

For guys with p0011/0021 if you have changed or cleaned the ocv, removed the oil screen. You guys might have to open up the cam gear unless you replace them, to do so you'll need a t30 torx plus 5 point bit, preferably with a 3/8 drive and then you can take it apart and clean it, trust me it works.

Unhappy 08+ STI 60k miles Cobb Stage 1

Hey guys, I really don't know what else to do, I recently rebuilted turbo because I saw smoke, and I checked that it has shaft play. I drove maximum of 200 miles and I got random misfire code in cylinder 4, I cleared the code and same day, after a bit of more driving, I got code P0011. Today I removed downpipe, and knowtised that I have turbo shaft play again. I removed intercooler, and there was oil in it. After I removed turbo of my car completely, I removed shaft and I saw few cracks on copper bearing, and shaft looked like it was under high temperature or friction, because it was all blue on the part where bearing goes.I later removed banjo filter from turbo feed line, and I can say that it was too dirty.****Note: before doing all thins I make sure that turbo feed line was not clothed up, I turned car few times, and oil went from it, so I don't think I was not getting any oil into my turbo*** Can someone help me with this issue, I will greatly appreciate it.

How do I know if the belt has or hasn't skipped any?
