I have a 91 acura Integra with 130,000 miles it started burning a lot of oil. I notice it smokes under hard acceleration. It has about 150 lbs on each cylinder when I did a compression test. I have tried several pcv valves on it, but it's still burning oil. About a quart every 300-500 miles. I pulled the intake and noticed a lot of oil inside of it. It has to be coming through a vacuum hose, but why? Please help.
It sound slike you have bad rings. You need to do a wet/dry compression test. That will determine if the rings are bad. It is almost impossible to replace rings in that engine. When it is made the rings are different size and are colored coded for size. Good luck
