Max Capacity Posted June 14, 2016 Share Posted June 14, 2016 I'm guessing we're looking for compression test results next ? Normally #2 or #4 are the ones with issues... Has the car always been on the stock MAP ? 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

lgtlongroof Posted June 19, 2016 Author Share Posted June 19, 2016 Hey Max capacity, we did #1 60lbs and #3 100lbs, didnt do the other side. At this point i'm looking at rebuilding the engine. MAP is stock along w/ rest of car. I just bought it 3 months ago from a place in Iowa(live in Wis) put 3k miles on it and don't beat on it. The only other thing i know is that #1 plug was NGK and different from #3 plug. So i'm thinking someone knew about the low squeeze etc and tried to make it work to sell. Oh well got a good deal on car and will keep. Thanks for your input and take care JA. Link to comment Share on other sites More sharing options...
