Hi everybody. New to the forum as a member, been lurking for several months... I have recently picked up a 1976 Chevrolet Pickup that has been sitting for many years (in a carport). Looks like it has been well maintained, but sat up for a long time. From what I can see through the oil filler it looks amazingly clean under the valve covers. I changed the oil first thing with Pennzoil High Mileage 10W40 w/supertech filter just to get it started. The question I have is does anyone have a suggestion to get the thing to stop smoking? Good compression on the 350-only 100K original miles. It smokes alot at startup and just a little after it is warmed up. I am thinking valve seals dried out and maybe a stuck oil ring-smokes alot when pushed real hard too. Any suggestions are welcome!
