Now at most engine speeds above an idle the truck is pushing oil out the top of the dipstick tube. The tube is on the pass side and the engine is out of an 89 truck. It coated the pass side of the engine, headers, frame, and everything with a coat of oil. Ive replaced the PCV valve and made sure the dipstick is all the way in the tube. What else could be causing it to do this? It pushed a quart of oil out in around 2.5miles. WHat can i check now?
