Seized RV8 Head Bolt
Discussion
Folks, currently stripping a RV8 and I've come a cross a real show stopper. The head bolt next to the exhaust port of no 8 cyl is seized solid. I've tried impact driver, air impact wrench, 3/4" drive bar and scaffold pipe and even attempted drilling out the head but I'm just er...polishing the head of the bolt.
Any ideas? I'm trying to avoid heat to avoid warping anything.
Regards
Iain

If you mean you've rounded it off you might as well grind the head off the bolt and then once you've got the cylinder head off the engine you can get medieval on the exposed length.Cheers folks, finally got the damn thing out using a 15mm impact bit (on what was originally a 16mm head). We used a combination of swearing, distraction methods, bribery and managed to avoid using heat.
Worryingly turned the engine upside down, removed the sump and there's only one bolt holding the oil pickup on, and that was loose by about 5mm. I'm thinking a monkey has been playing with this one in the past. Anyway onwards with the rebuilt and a bit of TLC!

Chassis 33,that is a common problem,i would recommend using blue thread lock on refitting of said pipe or staking & even lockwire the bolts heads Worryingly turned the engine upside down, removed the sump and there's only one bolt holding the oil pickup on, and that was loose by about 5mm.
