On my 67 Lemans I have a 455 out of a 72 Grand Ville that the previous owner put in. The motor is stock w/ 60,000 miles on it . The other night I was turning it 4,000 rpm's and then the oil pressure at idle went from 35 or so to 10 or so. Any Ideas?

First get another pressure gage and check it against the one you have. You'd really hate to pull your engine and find out the gage went bad (and they can do that).
If it really shows 10 psi at 4000 rpm and the oil level is normal then you've either got a pump that went bad or you have developed some serious clearance openings in the engine. In either case you had better tear into it. YTou don't want to drive it under those conditions. |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
