I think i saw a W2 that had a crack down there too. Torquing down on a bad head gasket or piston interference? Try some blue devil block sealer. Stuff works.
I agree. There are a lot of good things on the market that will take care of that. Even K&W has some new formulated stuff out. Some of the Blue Devil brand products offer a money back guarantee, so keep the container. It has the information right on the label.
