F22A6 Head bolt problem

[pupildel]

I Have a F22A6 that I wanted to rebuild. buy 4 of the heaD are stripl. and i cant get them out I have extraction tools and it end up just breaking. I try drilling it out and drill bit dont do crap. try blow torching it also no luck. those 4 bolt will not give (the 4 bolt are strip on the head part of the bolt)


what else can it try.....i might jus be selling the motor if those bolt dont come out

I assume you tried soaking it in a strong solvent / penetrating lubricant for a few days? Soaking it for a few days and then blasting it with some heat, and then finally removing it with an extraction tool should be all you need. Try tapping/knocking on the bolt / block where it's stuck while it soaks and while you try to extract it.

I'm not sure where it's stuck, but I assume that too much localized heat on your block could be a bad thing...

I had the same problem with mine. I never had any luck and I just used the engine as a core for an H22A. If you get the bolts out, great. If not, don't sell your problem to someone else. Unless of course you're telling them why youre selling it.

had this problem with a badly overheated f22. i ended up using a die grinder and cutting a slot through the head. you need to relieve the pressure underneath head bolt.

when i did that to mine, it actually popped.

^ done that for a fly wheel bolt lol worked nicely.

idk if this would work but maybe you can cut some of the head off two or three sides of the bolt and try using a different socket?

and make sure the drill bit your using is for metal and while your drilling make sure its got oil on it, that would keep it cool and possibly from breaking it.

i use an electrical impact hammer now, makes it so much easier!!

good luck man.
