I have a 1967 Ford Mustang 289 2bbl. Engine. It uses excessive oil. I have replaced valve stem seals. I ran a vacuum test on it and I have 20.5 inches of vacuum and the pointer on the gauge does not move or bounce with the car idling. I can speed the engine up and vacuum goes up a couple inches, still the needle on the gauge does not bouncing and then when I let off the gas the vacuum drops to 17 inches momentarily and then returns and holds at 20.5 inches of vacuum. There are no external oil leaks on engine. Ran a compression test on it and the readings range from 137 to 161 pounds. The engine has to be burning it but I see no tell tell smoke from the exhaust. I know the engine is old but I do not see what could be wrong with good vacuum test and fairly good compression test. Any ideas out there? :(
have the same problem?
