Well, following on from my first post,regarding the broken fin and buggered helicoil.Thanks for the answers guys, should get that sorted ok. However I then proceeded to remove the head, engine is still in frame, I foolishly thought I might sort out the helicoil and put her back together. It seems the cock that buggered the helicoil has also been playing elsewhere!! :oops:

Nothing that can't be fixed though.
Cam cap can be re-used, Just remove the bridge and use as two seperate caps.
Mark them so they go back in their original positions and all will be ok.
They were only made in one piece for ease of manufacture etc.

There's nothing like finding a use for those odd roofing bolts laying around.Some people should have their tools confiscated.

Thanks for that info ZED I would never have thought of that but it does make good sense. Looks like I'll be stripping the bloody lot now as I just don't know what other surprises may be in store down below :ghostface

Zed1015, whereas I agree the cap can be reused... What do you mean by "remove the bridge" on the #2 cam cap? I would have thought that the white metal bearing would have more support and stability without the removal of the broken joining bridge.

In 99% of cases these caps break as a direct result of an incompetant enthusiast.
Any extra support provided by the bridge is negligable and not needed.
Taking the broken material back and leaving a small protruding rib the same width as the thickness of the bridge instead of removing it entirely would make the most of any possible advantage (Leaving material on any wider than the thickness won't make a difference)
There is enough cross sectional area in the cap to perform it's normal function without any extra support.
This is backed up by the fact that the caps always break parallel to the bearing saddle and not across it ( Except in cases of extreme hamfisted bodgery, in which case the perpertrator should have their hands chopped off )
