Hello,
I had leaking pushrod tube seals and dropped the engine to make the job easier. I decided to pull the heads to check condition. I’ve done quite a bit of reading about whether or not gaskets should be used between the cylinder and case and between the cylinder and head. Some posters point to a service bulletin stating not to use gaskets. I have metal spacers/gaskets between the heads and cylinders. I think this engine has been rebuilt once before I got it. It runs well but it’s not as quick as another 914 2.0 I had years ago. Maybe the other car had higher compression and no gasket? I’m wondering if this metal gasket should be there. I haven’t checked for a gasket between the cylinder and case. My 356 has a thin copper gasket between the cylinder and case. Can anyone shed some light in this? Thanks in advance, Jack |

You have opened a can of worms with that question.
Lots of people say to leave the gaskets out because of a technical bulletin issued around 78 or 79 that says to. But the bulletin never mentions the 914 at all. They say to lap them like you would do for valves. I don't do that. I use the head gaskets. I cannot see how anyone other than a professional engine builder would be able to lap the cylinders into the heads and get the deck height to within .001. You certainly can't do it in a home garage. So one cylinder will be tighter than the other when that side is assembled. I have never had an issue in the 35 years I have been working on these cars. Clay |
