Showing results for tags 'throttle body adapter'.
Finally made it to a junk yard and found a 3300 with a decent vacuum port (the plastic part that sits atop the throttle body adapter). My Reatta came with one that had a couple flanges broken off and I've had doubts that the jimmied tube connections were really airtight. My question: Should some kind of sealant or adhesive or gasket go between the plastic part and the metal adapter body? The one on my car seemed to have a sealant, but the one on the junker didn't. Is a good silicon adhesive enough to make it an airtight and heatproof connection? Thanks!
