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 |

On any type 4 engine don't use the freaking cylinder to head metal gaskets as they leak. VW who actually built these engines came out later and said "No".

Do you base your opinion on what "everyone" says to do, or do you base your opinion on personal experience? How many Type IV motors have you built? Have you ever seen any issues with the head gaskets? Have you seen any issues because the head gaskets were left out? My personal experience is I have seen more leaks in the sealing surface because the gaskets were left out. And I have probably built around 200 or so Type IV motors. |
