Just finished the top end job on my '93 LS after a blow head gasket. Thanks so much for the valuable information! I have it all back together and running, but I have a loud tapping noise coming from the right front side of the motor. Any idea what it could be? I had the heads machined, so I'm comfortable everything is OK there. I understand that the valves are self adjusting, right?
I bought the car needing work, so I'm not sure if this tapping noise is normal or not. It runs ok, but I haven't run it more than a few minutes so far. Should I warm it up real well and see what happens?
