All right, speaking of waterboxer head gasket jobs. Anybody run into this :

2.1 engine, the outer rubber 'water gasket' on the left side started leaking about two months after a full valve and head gasket job to both sides.

I measure how thick the water gasket is - it's 3.7 mm. I measure what the gap is between the head and the block - I get the same thing...3.7 to 3.8 mm ...in other words the rubber gasket wasn't being compressed at all.

I figure I need half a mm less gap between the block and head, to compress the rubber water gasket about that much, a half mm.

I measure the thickness of the metal rings that seal the head to the barrels...they're 1 mm thick. I dig around in my old gaskets and find new metal rings that are ....magically....just what I needed - one half mm thick.

It put it all back together.....using the same new-near rubber water gasket cleaned up nicely, and my fav Toyota black silicone sealant. 'All fixed now' ( And now I wonder about the other side of course - but it seems fine., The van is at Burning Man now too. ) So anyone ever run into this before - that the metal sealing rings come in two thicknesses...., Or ?? Thanx, Scott
