Yep 100% agree. I would be lining up a new head without question.

If the gasket had broken else where I would have water in the oil.
Its not cost effective to replace the gasket Ive had quotes from
$6k-$10K , Cheaper to replace the motor as Mudski said

Dont you think its a motor out job to replace the head
then you have to changeover most of the gear, probably
a bit of machining I dont know

No. Can be done in situ. Sure it would be easier with it out but no machining required.

6-10k to replace a head is crap. More like 6-10k for drive in drive out engine replacement.

For someone who goes on about being in the industry ypu surely could get the head replaced for 2k or less. 3k at the most.

I've done it before on a surf, at home and for under $2k new head and all bits and pieces. Then I was told that my overheating was due to a crack in the block. Got a reconditioned bottom end for $3k and it still overheated, then I sold it.

Sorry mate, but I really don't know what else to say.

This is why I didn't want another diesel, especially one that is prone let go.

I'm happy with my gas blower, cheap to run and strong as nails.

That is why the cooling system is pressurizing,
I have not blown the gasket between the water channel and a oil line , as Id have water in oil
which I dont.

You seem to be like a cartoon character who has run out of hands trying to plug the leaks, stop one and another starts.
Not much help I know, just feel you are not in the right area to find whats wrong, fixing the result not the cause.

Lucky guess...
At least you have found it now.
