thisheregirafFe Posted August 13, 2013 Share Posted August 13, 2013 so as title says i'm getting some wonky AVCS in. numbers. right side appears to be working just fine, but the left is pegged at zero and won't budge. no drivability issues, no stalling, no funky idle, no power loss, no CEL. any ideas on that one? is it just not communicating correctly? any advice would certainly be appreciated... i can put anything i want down here?!

Underdog Posted August 13, 2013 Share Posted August 13, 2013 If it is calling for VVT advance and the AVCS isn't moving then there is either an issue with the electrical signal going to the OCV (which would cause a code immediately) or with the hydraulic circuit (which can take two consecutive driving cycles to trigger a CEL). Crack the banjo bolt open at the OCV with the car idling to make sure there is good oil pressure. If you are getting sufficient oil there then the filter isn't clogged. At that point I would try replacing the cam gear since the internal mechanism may be stuck. You could also disassemble the gear; I did a walkthrough on that a few years ago for a similar problem.

Massautowerks Posted August 13, 2013 Share Posted August 13, 2013 Wouldnt a OCV cause this also? I had a similar issue but the vehicle was throwing out a CEL, replaced both valves and it was solved. No drivebility issues either but the left side was definitely not working(checked with accessport) Here is where I purchased mine from: http://shop.bostonmotorsports.com/Subaru-Oil-Control-Valve-05-09-LGT_p_2002.html Link to comment Share on other sites More sharing options...
Underdog Posted August 13, 2013 Share Posted August 13, 2013 Yes - an OCV could cause this, and would throw P0011/P0021 (depending on the side). The Crimson Dynamo Link to comment Share on other sites More sharing options...
thisheregirafFe Posted August 13, 2013 Author Share Posted August 13, 2013 well there's yer problem right there... good god. somehow i must've snapped the ocv relay right off. i swear to god. sooo, given it's the left side, am i going to starve anything of oil? it's already been on the dyno and 50 miles back/forth to work like this... edit: i still don't get how this doesn't throw a CEL i can put anything i want down here?!

-Samurai- Posted August 18, 2013 Share Posted August 18, 2013 I would have sold it to ya for 50 free shipping lol. But glad you were able to find the problem quickly anyways. Link to comment Share on other sites More sharing options...
