Continuing with the scrap Moggy engine. Time to remove the cylinder head.

A simple job I had no trouble with except the usual studs coming out with the nuts. Some mong had sliced through the radiator hoses so that will limit runtime when I get it working unless I cobble together some replacements.

No drama here. No sign of HGF or any other damage. I'll use the head gasket again. I tried turning the engine with the starting handle again but I'll be damned if I can get it to budge. The diesel down the bores hasn't penetrated. Next I'm thinking of warming up the block by pouring increasingly hot water in the water jacket to expand the metal. Don't really want to start thumping the pistons. A couple of valves were stuck open but they easily shifted once I got the head back home.

It wasn't a pretty sight but this is all what I'd expect from a motor that's been standing for decades. It never made it onto the DVLA system - something I am trying to change.

Now to remove the thermostat cover without destroying it. One sharp tap and it was away.

And the thermostat. Already open so probably kaput. Looks like the original. 82 degree rated. Here a Stanley knife and gas bottle came in handy.

After I'd heated it up, which caused it to open some more, it soon yielded. Minimal damage caused but it is no use stuck open. Proper Smiths bellows job too.
I removed and numbered all valves, which are all in good condition with no burning or coke formation. A big clean up and lapping in is all that's needed along with new valve stem seals. If the springs measure up OK I'll re-use those too. It promises to be a good little engine provided I can free up the pots.
