I should’ve taken the time to do this when the heads were off. The set screw would’ve been so easy. Maybe if I’m careful, I can grind the helicoil away (catch the filings with a towel), rap the hole, spin the oil pump a little with a drill to flush the hole while being careful to catch those chips.
Hey, do you know of any valve covers that might work? The stamped steel chrome covers I have don’t look that nice and don’t seal that well.
