Despite wise words. - Dave
Despite wise words from those who know better I'm gonna give it a go with the Helicoil next Monday.

The heads' a gonner anyway. I'm sure a seeping gasket would be more obvious than a bit of rust on all 4 plugs so I'm gonna assume that *is* ok.

If the guy fails/wrecks the head I'm down 45 quid. If It succeds I've bought some time - possibly the lifetime of the car before I have to change the head.

If the swarf/floating helicoil kills the engine itself...

Well, I'm hoping aliminium filings against steel valves/pistons etc won't do that...

Anyone with a better plan in the meantime speak up!!!!

Dave, you should not get the filings in the engine if the cutter is well enough greased to retain them. Good luck. We've just had a Metro sump plug done.
