Re: Need advise on Isolator/Intake repair..
I checked today for the hole in the 5 o'clock position inside the valve cover and could not see one. I have the black valve cover; most have described the replacement as a silver cover. I have not taken off the intake cover to see if a previous repair has been done. I guess that will be required to be for sure.
1. Can someone tell me exactly where the knock comes from? What is hitting?
2. I can find no external air leak causing the 171/174. Is the leak internal? And will the isolator bolt correct the CEL code? Other than the knock and the light, the van runs smooth.
thanks, JoeJWill
