I have read that the efr guys have gone threw this wondering if the GtX guys too. Oil smell threw ac when at stop .I'm thinking its gotta be this. I have searched low and high not a drip of oil. Compression test solid 175 across all 4 . No smoke or smell at start up . Just after I've been driving and come to full stop. Any input. Running catch cans and PVC plate .any suggestions?
