This picture makes me pretty happy too. you see it? NOTHING on the floor.

It looks like youtube put the last run video on peoples home pages this morning so for a couple hours I was on my way to becoming a youtuber....for a couple hours anyway

6 has me nervous and 7 in the middle scared

Ok...I need to admit failure on multiple fronts. It looks like 6, 7, 12 are for sure leaking, the WBo2 sensors are giving me BS numbers, a couple drops of oil on the floor, and possibly coolant temp still but not certain.

After sleeping on it the though this morning is copper head gaskets. My current thinking the problem here is that the end cylinders are not supported the same as the inner cylinders which is why the factory composite head gaskets had metal reinforcing on the ends to limit completion in that area which sees about double the force the between cylinders area sees and is no doubt distorting something leading to failure.

The guys using MLS gasket+sealant are having success because MLS is not compressible. They have sealing ridges that act like a spring and a very thin rubber coating to make a seal....but that hasn't been working either, my guess is a bit of the same issue I have....the uneven clamping forces cause just a little too much distortion. So add sealant to the basically incompressible gasket and success.....doesn't seem much different than a much cheaper to 1 off copper gasket+ sealant.

I'm also pondering less torque on the end studs.......

Aren't there two sealing issues ?The cylinder liner and the water ports .I would think that sealant would solve the water ports -The cylinder liner is a bit tougher .

No, its the liners not sealing to the head, which allows coolant into the cylinder. There is nothing to seal the liner to the block so if the liner is not sealer to the head there is coolant in the cylinder

My record keeping is not what it should be....I can not find the drawing for the head gaskets. I did find a hard copy with some markups on it to add missing dimensions....I'll need to check it against the used gaskets just to be sure before trying to order copper gaskets somewhere.

Edit - it looks like cometic makes copper, I'll start with them and it looks like I already cleansed up the old gasket so nothing available to check until I pull the engine apart

I get that .I was reacting to possible perimeter head leak .

That would be a new problem...but new gasket idea would likely come with new problems
