I would not have thought a gasket leak would have caused HG failure, but it's possible I suppose. Running lean on one cyl, detonation/heat frying something?

The other thing that occurs to me is does it have a water heated inlet manifold, like some 164s and 240s?

If so, there could be a different link between your gasket change and the overheating. Maybe the new gasket was faulty, or slightly the wrong spec, and blocked a water-way through the manifold? Maybe it had one of those pre-cut "holes" where you have to push out a bit of the gasket before fitting; may not have been done?

Dry I'm afraid, John.

Will go up Saturday to suss out the heater. It's not the end of the world to change one, just bloody fiddly.

As to the compressing problem, maybe we should run the h/c test AFTER it cooks up the next time, what d'you think?

Thanks again, Nick.
