MasAyinde Posted May 12, 2016 Author Share Posted May 12, 2016 I disassembled it and reassembled it, and apparently that process has a history of going wrong. I think something inside is seized. Link to comment Share on other sites More sharing options...
FJuan Posted May 12, 2016 Share Posted May 12, 2016 Most of the time when the AVCS is defective it would throw the P0011 or P0022 depending on which side. My wife's balls are delicious. Link to comment Share on other sites More sharing options...
xt2005bonbon Posted May 12, 2016 Share Posted May 12, 2016 I remember way way back somebody posting about a small piece that broke inside that cam gear and got it stuck. Link to comment Share on other sites More sharing options...
FJuan Posted May 12, 2016 Share Posted May 12, 2016 I remember way way back somebody posting about a small piece that broke inside that cam gear and got it stuck. I damaged my driver side cam gear during my install. Car ran fine while driving, but would idle a little rough. Then got the P0022 code, that's when I discovered the cam gear was damaged.

MasAyinde Posted May 12, 2016 Author Share Posted May 12, 2016 Most of the time when the AVCS is defective it would throw the P0011 or P0022 depending on which side. Ordinarily it would, but right now it's defective and there's no code, so I'm kind of at a loss besides this. I damaged my driver side cam gear during my install.

FJuan Posted May 12, 2016 Share Posted May 12, 2016 How long were you driving around before the CEL? It took about 10 mins of driving (break in) after the motor was in. All it took was a few stop and goes for the ECU to detect the rough idle. My wife's balls are delicious. Link to comment Share on other sites More sharing options...
MasAyinde Posted May 12, 2016 Author Share Posted May 12, 2016 Hit the AVCS gear with a rubber mallet as best I could with the radiator in the way. Max advance went from 2* to 7*. I think that might be the ticket. Link to comment Share on other sites More sharing options...
FJuan Posted May 12, 2016 Share Posted May 12, 2016 After you corrected the timing belt, did you drive it around until IAM was at 1.0? Just trying to figure out myself before you have to go spend another $150 +/- on a new cam gear. My wife's balls are delicious. Link to comment Share on other sites More sharing options...
MasAyinde Posted May 12, 2016 Author Share Posted May 12, 2016 I actually loaded a map with initial IAM of 1.0. I had a feeling that if it was a seized gear, hitting it with a rubber mallet would make a difference, and it did Link to comment Share on other sites More sharing options...
FJuan Posted May 12, 2016 Share Posted May 12, 2016 Ok, let's hope that fixes the issue. My wife's balls are delicious. Link to comment Share on other sites More sharing options...
MasAyinde Posted May 17, 2016 Author Share Posted May 17, 2016 Decided to take the plunge and rebuild my AVCS gear carefully. Advance is now up to 44* on the left side and 13 on the right, but naturally I messed up the timing again. Oh well, gotta take the belt off again but at least my AVCS issue has been fixed.

FJuan Posted May 17, 2016 Share Posted May 17, 2016 Good to hear, and I hate the timing belt on these motors, such a PITA!! My wife's balls are delicious. Link to comment Share on other sites More sharing options...
MasAyinde Posted May 17, 2016 Author Share Posted May 17, 2016 At least my belt still has the timing lines on it so it should be easier. I was just a little rushed. Good to know that my car will be fully operational for the 10+ hours of driving I have planned this weekend. Link to comment Share on other sites More sharing options...

FJuan Posted May 17, 2016 Share Posted May 17, 2016 My guess was sludge build up in the AVCS. My wife's balls are delicious. Link to comment Share on other sites More sharing options...
MasAyinde Posted May 17, 2016 Author Share Posted May 17, 2016 Actually, I am confused. How do you come to the conclusion that now the AVCS gear is working? The left AVCS that was previously maxing out at 7* is now advancing fully to 44* and it follows the configured values in the map. Link to comment Share on other sites More sharing options...
MasAyinde Posted May 19, 2016 Author Share Posted May 19, 2016 AVCS right advance: 43* AVCS left advance: 44* Damn dirty AVCS gear!! All that trouble for a little bit of gunk blocking the gear. Also, did the timing last night and it is now the most on I have ever done for a timing belt job. I'm talking still lining up perfectly after idling for 2 minutes.

fahr_side Posted May 19, 2016 Share Posted May 19, 2016 Left is stuck at 0, going to 1 and 2 every now and then, seemingly randomly. AVCS right advance: 43* AVCS left advance: 44* Just FYI, resonance in the belt, a little slop in the AVCS gear etc. will have the cam positions move by 1 or 2 degrees every now and then. Even a completely dead AVCS system will show 1 or 2* cam advance angle change with the engine running. Obligatory '[URL="http://legacygt.com/forums/showthread.php/2008-gh8-238668.html?t=238668"]build thread[/URL]' Increased capacity to 2.7 liters, still turbo, but no longer need spark plugs.

xt2005bonbon Posted May 19, 2016 Share Posted May 19, 2016 It's interesting cause both of my cars never get that much advance. Max advance on each side is like 11. All in the tune I guess.. Link to comment Share on other sites More sharing options...
MasAyinde Posted May 19, 2016 Author Share Posted May 19, 2016 Willing to upload your tune? I use a variation of the Mickey D stage 2 WRX tune I found on the RR forums. I have a VF52 so I created a hybrid map. Link to comment Share on other sites More sharing options...
xt2005bonbon Posted May 19, 2016 Share Posted May 19, 2016 Mike @ tuningalliance did them. So I may not upload them . Now that I think about it, maybe we're both seeing about the same amount of advance: my 'overall' timing variable shows while cruising a max of 49 deg, while each AVCS shows 0 deg. On a different note, you may want to help that guy. Different engine but kinna similar codes.. Can someone please advise to me which solenoids are my (ocv,vvt, avcs). It looks like I have 4. I've been throwing cel for P0021-camshaft position timing over advanced bank two P0018-crankshaft position-camshaft position correlation bank2 sensorA P0016-crankshaft position - camshaft position correlation bank1 sensorA P0011-intake(A) camshaft position timing-over advanced(Bank1) Also randomly throws cel for misfire on all 6 without these codes. http://estore.subarupartswarehouse.com/images/parts/subaru/fullsize/B13_00601176.png Link to comment Share on other sites More sharing options...

Mike @ tuningalliance did them. So I may not upload them . Yeah, that's why. The stock tune on the '07+ calls for around 40deg advance in the low-load/low-RPM region: http://legacygt.com/forums/showpost.php?p=5030757&postcount=76 See covertrussian's findings on AVCS tuning: http://legacygt.com/forums/showpost.php?p=5027119&postcount=70 Link to comment Share on other sites More sharing options...
