I'm about to remove the head from my engine and I'm a bit concerned about the 2 cylinder head bolts. They look like they're waiting to snap! Anyone got any advice on removing them please?
Thanks,
Rod

Just don't do it tonight, Friday the 13th and all that...... They're bound to snap. Wait till tomorrow.

My tacho housing bolt is as stuck as a very stuck thing but I am confident it will move with a blowtorch and some patience.

I`ll let you know when..........................

.....................it`s snapped :cry:

is heatingthe answer? bolts will be steel but engine is aluminium alloy - the latter will expand more than steel when heated thus making it tighter?

run a scriber between bolt/head interface and apply penetrating fluid - not ~WD40. aloow to soak. the fluid may lubricate the bolt head as you undo it.

.... but chances are it will snap if it looks like its gonna

Thanks for the advice, I gave them a little tweak and they came out easy. Maybe it was the leaky cam cover that kept them all nice and oily!

Anyway, I'm going to switch to a project from now - looks like its going to be a long one.

Cheers,
