How much damage could have bee
How much damage could have been done if my engine was not pumping oil strong enough. I heard a scraping noise for a few seconds so I shut down. It started right up and ran fine but at 3000 rpm's it sounded bad. It happened for a few seconds about 3 times over a 10 day period while testing and troubleshooting maybe a total of 10 seconds or less. There was no tapping and it runs great at lower RPM's. Could the wrong oil or filter do this. The other engine is fine. Both engines' oil changed at the same time. Also rund hot when this happens.
