there is also some liguid that come out of the BOV could be a oil, coolent and dirt all mixed together its hard to tell it never ever makes blue smoke other than after a slow shift then as soon as ur on the gas it makes a big puff of smoke. Only at higher rmp;s to it seems im probaly gunna pull it appart tonight and maybe change out the turbo… ---

i was told if i add a little bit of oil in the cyliners with low compresion then do a compresson test for that cylinder and if the compression goes up its bottom end related and thats exactly wat happened but i dunt know how accurate this is with diagnosing the problem ---

If you do a wet compression test which is when you put oil in the cylinder and the compression goes up compared to the dry test it means your rings are leaking. Doing that just rules out that it’s not a valve problem. ---

Doing that just rules out that it’s not a valve problem. Thats wat i did compression goes to normal so i am assuming its bottom end i already pulled the motor out and i am either buying another one from speedtech or getting mine re-ringed ---

probably cheaper to fix yours, condering you can do the disassembly / assembly yourself. ---
