I have to post this because of your reply posts to the others, you posted here for help, when those who did respond responded you doubted there adivce to the fullest,to me it even sounded like you were saying they were wrong, not that you did just my impression, if your such a competent mechanic why did you ever post here in the first place? just my words here, most of these guys on here know the cars and these cars so well they can tell you how to take it apart piece by piece and name each piece while your doing it, i would ask just for myself give them alittle respect. good luck with the job you have ahead of you the 16 valve engines can be pretty touchy.
