I bought a parts hauler a couple of weeks ago. It is a little 93 Plymouth Colt Vista. It has a 2.4L engine in it. The question I have is that there is a sticky ring in it. When I start it it blows a little blue, then it is gone. I was told that it would go threw about a half quart of oil every 1000 miles. It has 90k on the engine, and had head work done on it not long ago. My question is.. Is there something I can add to the oil to loosen up that ring?? Thanks..
