Default Re: Suggestions for removing seized cover bolts??

yeah, an impact driver is great, but on a lot of bolts i've seen, it's too late for that. there's nothing for the bit to grab onto.

the drill method is simple, and the phillips head bolts help to center the bit. it takes about 30 seconds to drill through the head, and as long as you don't go too big on the drill bit, you won't damage the cover.

there's plenty of threads to grab onto after the cover's off, they're not flush with the engine at all.

this method is a last resort, but if you're gonna replace the bolts anyway, it's quick and easy.

the best method is prevention. replace all the bolts on a brand new engine, use anti-seize on all of them, and you'll never have a problem.
