So my DT project, got the engine off the frame. Had really low compression and was filthy. Cleaning it off, I was about to start opening the engine to inspect inside. Nearly every screw on the engine is stripped the F out. I see lots of people drilling stripped screws with screw extractor kits. Has anyone used these before on engines? Any advice or tips as to which kit to buy and how to use? Is there a better method of removal? Thanks in advance!
