2.5D leaking at head gasket area:

Yet another chapter in the unending saga of my 110/2.5D engine swap...

Got the engine back together after replacing a piston with a broken ring. All set, oil in, water in...what's that noise?

Water running in volumes from the join between head and block at the back right.

BUGGER! BUGGERBUGGERBUGGER!

So, off with the head (again!) to find a perfect head gasket and nothing obstructing the seating.

Howwever, I did notice at the point of the leak a core plug which had been previously covered completely by the old head gasket but was not by the new Payen gasket. What engineering genius puts core plugs on a block/head mating surface?

So, I suspect given the volumes of water that were coming out of the leak and its position that this core plug was bad. I am...annoyed.

Question for the assemblage is this - how likely is it I've found the issue - has anyone ever seen this - and is this just a common 18MM core plug or is there some insane reason i should buy rel LR one...

Right about now a Jeep is starting to look VERY good...

I had same thing when I first put mine together but it was down to me not tightening the bolts down gradually. I hope it is just the core plug, it is a good sturdy engine.
