Rocker cover bolt seized
Staple balls - 27/3/09 at 06:28 PM

Right, about 4 years ago I refitted the rocker cover on my pinto with handy bolts.

Turns out one of them (a countersinky one) wasn't stainless.

Needless to say, it's rusted to buggery, and I have no way to get it out.

Suggestions?

What sort of bolt is it? Hex head?

If you can weld a bar to it as a lever it'll come out. The heat shock should losen the rust and will give you something to pull on to get it undone

Yup, that's what I was thinking, but y'know ask the experts

A sharp strike with a hammer also gets things moving and dousing with penetrating oil.

If worse come you worse and it shears off it not the end of the world, grind the top flat, dot in the middle and drill out, just watch the swarf and grindings stay outside the engine.

As said a few clouts with a hammer and drift directly on the top should help . If it shears then weld a nut onto the remains if you can. The heat will help to shift it. Having seen loads of peoples attempts to drill out broken bolts I would suggest practice on something scrap before trying on your head. Do not try Easiout extractors , the best place for them is in the bin.

Piss, that's well stuck.

Some caress with hammer and drift got me nowhere

Welded a nut onto the head, broke a spanner and crushed the nut.

Will try a bigger nut tomorrow, maybe stick a bolt into it to stop it crushing.

what fun.

M12 nut welded to the remains of the bolt (and filled with weld) did the job nicely.

FFS for a 6mm bolt???? what the hell did you put it in with?? Loctite and welding??

Glad you got it out though.

That's the thing, it was barely done up originally and had some copperslip on.

Still, beat the bastid

Lol!

It's not even 6mm is it? Rocker cover are 4mm tops I'd have thought.

That's a bit unfair, they probably keep the spark eroding places in business
