The plan today was to make up some temporary radiator hoses to get it running.

Managed to hack out the broken fitting, will buy a new water pump anyway but wanted to do some testing today.

Hacked:

I then found a fitting that worked, put some rtv in it since the threads were damaged. Again, just temporary.

I was going to block off the hose since it is just for the heater But thought I should loop it to the other end. Pulled off the hose from the intake manifold and found it was completely blocked with white powder. It was rock solid, had to drill it out.

Ended up having to take the intake manifold off and found it was blocked in the head too. I must be some kind of long term reaction with the brass fitting?

That oval recess above the stud in the centre is meant to be open and is blocked with more white powder. This stuff came out easy though. Can now see into the head with no blockage.

Need to buy a new intake manifold gasket now.

Checked out the intake ports and they look  like they could really do with some basic porting. It’s not even uniformly round lol.

I’ll compare the gasket to the intake port and manifold runners to see.
