Jimmye212 Posted July 17, 2017 Share Posted July 17, 2017 So I have a pretty big problem here. I have a stage 2 09 GT 5eat with 130k miles on the engine and 160k on the body. Last night I overboosted bad in first gear, and afterwards I noticed a lot of oil being spit out of my gfb blow off valve. Basically I'm wondering if it's blown turbo seals or a cracked ring land. I checked the turbo on the downpipe side and there isn't really any shaft play. The only reason why I think it isn't a cracked ring land is because my engine was apart 10k miles ago for head gaskets, and my mechanic said that the pistons were very tight in the cylinders and in good shape. Thanks for any help. Link to comment Share on other sites More sharing options...
