1967 Ford Mustang 289 small block engine. It uses excessive oil, about a quart every 500 miles. The exhaust does not show excessive smoking. I have replaced the valve stem seals. This did not slow the usage down. It has dual exhaust and when running engine sooty oil comes out of the tail pipes.I have run Marvel Mystery oil to try to loosen stuck piston rings. This has not helped.
Any suggestions as what my next step should be to try to stop the oil usage. Thanks
have the same problem?
