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 |

Thanks Len. I do have a shim at the base. Would it be correct to assume that the base shim and the head gasket created a 1mm or less deck height on a stock engine? If so, I will need to calculate how thick the base gasket should be to be under 1mm at the head. Have you been through this? If so what shim thickness did you choose? I’ve read that stacking shims is not the best way to create the needed space.
Thanks for your help. Jack |
