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 |

I beleive they left them out because of the hydraulic lifters needing more oil than the solid lifter engines. They changed the casting for the Buses with hyd lifters.
They probably figured out they didnt need it. Most of the race engine builders I know prefer that case. One less thing to fail. The worst that can happen: more oil in the heads under sustained high RPM driving. B |
