mkee87 Posted February 12, 2015 Share Posted February 12, 2015 I've been having issues with a rough idle and stalling in stop and go traffic. I logged to see if anything looks queer and my acvs looks all out of wack to me. Any opinions will be greatly appreciated. https://docs.google.com/spreadsheets/d/1bVQ7zciY204E48aUGmbPB2i8c_oArKZCUirqXDYcAs4/edit?usp=sharing Link to comment Share on other sites More sharing options...
xt2005bonbon Posted February 12, 2015 Share Posted February 12, 2015 I think that is correct. They do look out of sync. From what I understand, they should always be within 1-3 deg of each other at all times. One of them is doing its own thing here. Probably time to clean them up, or replace them.

mkee87 Posted February 13, 2015 Author Share Posted February 13, 2015 I took them out and inspected them. Both of them move smoothly and weren't gunked up at all. The passenger side one didn't want to come out at all though. Link to comment Share on other sites More sharing options...
xt2005bonbon Posted February 13, 2015 Share Posted February 13, 2015 Yeah passenger side is pain to take out from what I understand. Then I think you should also inspect the banjo bolts that are notorious to get clogged. There is one on the driver side closed to the OCV right behind the timing belt cover. And the other one is bolted on the passenger side head closed to the turbo. passenger side: http://legacygt.com/forums/attachment.php?attachmentid=65157&d=1237512742 driver side: I finally got around to pulling both of the Banjo filter bolts. The turbo one was about 50% plugged. And the driver side ACVS unit was 25% plugged. Pic. of turbo Banjo filter. Over 73k on my GT http://i99.photobucket.com/albums/l293/HAMMERDOWNGT/Subaru/0812072233.jpg http://i99.photobucket.com/albums/l293/HAMMERDOWNGT/Subaru/0812072235.jpg I stated this earlier. http://legacygt.com/forums/showpost....7&postcount=44 But change my mind. Do to my oil\filter change history. I put new filter bolts in to see if the clogging took place more in the first 30k Mobil1\Fram or the last 43k, using Amsoil oil\filer. The driver side Banjo filter bolt is right behind the top cam pulley cover. http://i99.photobucket.com/albums/l293/HAMMERDOWNGT/Subaru/0813071900a.jpg http://i99.photobucket.com/albums/l293/HAMMERDOWNGT/Subaru/0813071900.jpg To remove this bolt. You have two options. 1) Pull everything of the front driver side of the motor to pull that cam pulley. So you can remove the rear cam belt cover. To have room the remove the banjo filter bolt. 2) This is what I came up with to service this bolt, without doing #1 above. Make sure the engine compartment is still warm. Plastic bends better when warm. Need to remove the AC bracket by the oil dipstick, unbolt the dipstick ( if you choose to remove the dipstick for more room. Put a oil drain pan to catch the oil that will leak out of the dipstick tube.) To make room for a cut tool ( I use a dermal with pen attachment & 1\8 in. milling bit.) To remove the tit off the head of the banjo bolt. Then using 17mm wrench to break it free. Unbolt the other end of the AVCS oil supply line. Now the fun begins. Once the filter bolt broken free. Than take a old 17mm box end wrench & grind it down to 3\16 thick & unscrew. Or try this http://www.sears.com/craftsman-7pc-h...blockType=G212 Use a pry bar to move back the rear cam belt cover. Remove filter bolt & line together. Clean up the head of the bolt. I ground it down between 1\8"- 3\16". http://i99.photobucket.com/albums/l293/HAMMERDOWNGT/Subaru/0815071950.jpg http://i99.photobucket.com/albums/l293/HAMMERDOWNGT/Subaru/0815072338.jpg Quote: Originally Posted by HAMMER DOWN http://legacygt.com/forums/skynetim/buttons/viewpost.gif This would be me:p:). 2 microns filtration, 15k OCI, Cobbs stage 1 93 tune, 16.2 psi. of max boost & 169k+miles on the original motor & turbo. Took the original ones out at 73k. Another 4k I will have 100k on this set of banjo filter bolts. Then I will inspect & if all is fine. I will leave them out. If I have crap in them. I but new ones in & change them out every 100k. Mike Link to comment Share on other sites More sharing options...
MrTris Posted February 13, 2015 Share Posted February 13, 2015 Where'd you get the picture of the cool cutaway motor? Link to comment Share on other sites More sharing options...
xt2005bonbon Posted February 13, 2015 Share Posted February 13, 2015 Where'd you get the picture of the cool cutaway motor? Can't remember. I found it maybe three years ago to help others figure out where the banjo bolt is located. It's a nice picture. Link to comment Share on other sites More sharing options...
mkee87 Posted February 13, 2015 Author Share Posted February 13, 2015 So based on my log which one do you think needs the replacement? I was only able to buy one. Link to comment Share on other sites More sharing options...
xt2005bonbon Posted February 13, 2015 Share Posted February 13, 2015 Not sure at this point. Maybe you should do an 'acceleration' type log, an idle log, and a cruise log. Then post them here. Link to comment Share on other sites More sharing options...
