Wow !!! I knew I would get a response to this question but not so many. But the more the better. Cool !! So check it out... I overheated my 04 and don't have too much money to rebuild the complete motor so I did a valve job and now my car is smoking . I'm starting to think the new compression on top is to much for the rings and was wondering if this stuff would clean them so I don't have to tear it all down again . Thanks for all answers.
