There should not have been ANY head gaskets.
Inspect the head carefully.That breach of the gasket probably wore away some of the mating surface. If it is not too bad, the heads can be machined to get a new surface. That will raise your CR if you do not shim under the jugs the amount that was machined off. Stu |

Stu I disagree with you, and I've been building T4 engines professionally since 1973. With the exception of the VW 2.0 engines with the redesigned heads (covered buy the TSB), I always install the head gaskets per the factory service manual. Jake Raby builds them without. He has a different view on the subject, and that's fine with me. Doesn't change either my experience or my opinion. The Cap'n |
