GC engine case ?

[cary]

I have a GC xxxxxx engine case that I might use on my 2.0 rebuild. But after examining it, it doesn't have the lateral oil pressure relief piston above the #1 lifters.
What exactly does that piston do ? Will it be ok without it ?

[Jake Raby]

It may be a GE case..... the only engines that did not have the relief were Hydraulic from the factory

Actually, a lot of the 73+ 914 engines did not have that relief. Cary, your GC is from a 75-76 2.0 914 or a 76 912E.

Never seen one yet that did not have the provision for it...... Even my 912E engine has it, and that case is exacting a GC for a 914.

Oh well, guess I'm not well informed on these engines!

GC 003700 .............from memory here at work.
So I'm ok to proceed, I take it ?

Thanks for the great video, Jake. I'm going step by step.
Enjoying your smiling face ............... LOL

Full steam ahead...

No, no, Jake. That's not what he said. It just isn't machined and the pressure relief valve installed. I have a GC case that I'm saving. It's just as Dave said. The boss is there, but no valve prep.

Yep, boss is cast into the case. But not drilled and tapped.
