I need to remove the heads off of a newly rebuilt engine (4-cylinder) I built (never run). They have already been torqued. Are the head gaskets and gasket between the cylinder and block, compression gaskets that should be thrown away (i.e., replaced with new one) after I untorque the heads?
The head gaskets will be easy to replace. But I'd have to pull the cylinders to replace the ones between them and the block. |

i could be wrong but what i see is a deformed gasket from improper torquing sequence, not a gasket failure. looks like one side was over tightened causing the gasket to deform. you can see the result.

Look pal, DIY's come here for advise. There are a host of professionals in various specific fields that apply directly to some of these questions who help our fellow 914 lovers. In this particular case the O.P.'s question related to a very specific apect of an engine build. This issue was addressed by VW 40 years ago. It's actually settled technology. And as if that weren't enough, at least 3 engine professionals - myself included -with well over 50 years of combined T4 engine experience chimed in to help advise the O.P. I have no problem with your disagreeing with me. I really don't care. But you do a diservice to the O.P. and others tryiing to learn when you argue from a position of ignorance. You've done this on other threads as well and have exhibited the kind of behavior that contributes to the spread of misinformation that the internet has, sadly, become famous for. I know a lot of professional aircooled VW engine builders, and not a single one of them uses head gaskets on a typical build. Are you the one professional exception, or just an internet troll? That's a rhetorical question. Based on your technical postitions, I already know the answer. |
