Thread: 1970 Chevy V8 oil usage

Yep, the rings didn't seat. Warm it up, and run it at 2500 RPM for a while, it will probably make visible smoke then. Or run it at highway speeds, then let of the gas until you are down to 30 or so. Boot the gas and watch out back, a big puff of smoke means bad rings. Either live with it, or re-ring it and break it in right. BTW, what oil are you running? Synthetics won't let the rings seat. Break-in should always be done on dinosaur lube.

The car does not have any visible smoke, runs fine, there are no leaks. Does this still mean the rings have not seated. I purchased the car with 1500 miles on the engine and then drove it back to my state across country, which was another 1400 mile road trip. I am using regular old Penzoil 10-W40.
