Hey guys, for a while now my Mustang has been pushin some blue smoke out of the tailpipes. It does it on hard acceleration, or coasting down a hill when i get back on the gas. I'm thinking it might be valve seals, but at the same time I wonder if it could be rings ( hoping not). I compression tested it, 125-140 on all 8, motor seems to run fine other than this issue. Are these engines known for toasting rings? I'm honestly not sure how many miles are on the engine, its definetly not original though. Any help would be appreciated!!
Thanks!!
Thanks!!
