rob-2 Posted January 27, 2014 Share Posted January 27, 2014 Low compression, bet those two are bust. Happened to me and it required a rebuild. Link to comment Share on other sites More sharing options...
LatentWagen Posted January 27, 2014 Share Posted January 27, 2014 Could be oil control valve on that side, or intake manifold gaskets. Check the misfire threads. If it's actually running well above idle/1000rpm, it probably isn't rebuild time, yet... LW's spec. B / YT / IG Link to comment Share on other sites More sharing options...

rob-2 Posted January 27, 2014 Share Posted January 27, 2014 Stop driving the dam thing. If you haven't ruined the motor yet you're going to! Link to comment Share on other sites More sharing options...
Max Capacity Posted January 27, 2014 Share Posted January 27, 2014 P0021 and P0011 are normally a bad sign. Pull the drivers side OCV and make sure its clean and slides easy. You may also want to check the banjo filter on the rear top of passenger side head. I have both banjos on my new engine removed in my 05 After I got both those codes my turbo went soon after. check the DIY's. A can of engine flush and a couple quick oil changes may be a good idea too. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it. Engine Build - Click Here Link to comment Share on other sites More sharing options...
Bbc84 Posted January 28, 2014 Share Posted January 28, 2014 I had cyl 2 and 4 random misfire for a while that I never could figure out on my beater, when I finally took it to a shop they also found p0021 as well along with misfire codes. turns out previous owner of my car had timing belt done wrong, one of the cam sprocket on drivers side was off by 3 teeth.

Cptxbig Posted January 28, 2014 Author Share Posted January 28, 2014 No shit I just had my timing done and then this all started I'm gonna have them check that again thanks Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
lee07 Posted January 28, 2014 Share Posted January 28, 2014 If not, have them do a leak down down test so you can rule out valves and piston rings Link to comment Share on other sites More sharing options...
Cptxbig Posted January 28, 2014 Author Share Posted January 28, 2014 They did a dye test I to check if it was the head would that be the same test for the leak Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
LatentWagen Posted January 28, 2014 Share Posted January 28, 2014 If we're talking about the same test, the "dye test" is for a head gasket leak. If that test were going to be positive, you'd know it already. Smoke, overheating, oil in coolant/coolant in oil, etc. As said before, have them do a compression and leakdown test. You're looking for evidence of low compression (could be piston or piston ring damage), or a leaking head due to sticking/bent/burnt/broken valves. LW's spec.
