ok so I have a situation where I am getting blowby into my coolant. I checked the heads and jug decks for flat.....good there. aside from a cracked cyl, or bad head gasket, where else could I be getting exhaust in the coolant? it seems to me that I have no reason to go deeper than the jugs as it is for sure burned fuel in the coolant.

also, does anyone have a template for a test plate for AC 900 jugs?

Check your base gaskets. Could be leaking into the coolant jacket.

I thought of the base set too, but the fact that I am getting burned fuel in the coolant makes me think it mst be at least as high as the exhaust port.....no? is there exhaust pressure down at the base.....I was thinking it would be pretty much vacuum down there.
