recently i changed my leaking header gaskets and motor mounts. upon driving home i got small pop follow by a blue smoke and bluish green oily fluid on the passenger side fire wall. i heard it dripping. but no visual. i have no overheating fluid lose however i noticed my a/c line rubbing the header and my a/c not doing its thing. im partially knowledgable with cars and not afraid to dig into it. can anyone give inputs on to trouble shoot this? i lived within 5 miles from where i did the work.
