I have a '76 2.0 with GC case. There is no oil pressure relief valve in the case. The one between the pushrod tubes at cylinder 1. Just a deep hole, as cast.
So how exactly did VW handle oil pressure relief in this case? The engine ran just fine, and extremely reliably for 98000 miles, which is when I tore it down to rebuild it. Jim |

The way it works is that the valve at the front end of the motor does the work. Instead of having one valve at the "end" of the system that opens up when pressure gets too high, and another one at the "beginning" of the system that does approximately the same thing, they just went with the one at the beginning. That's the one that is covered by that plug with the large slot in the end...
