PVC for a 76 B21

I added LH 2.2 and the turbo setup from an 88 740 to my 76 242 with the original B21 engine. My PVC is run off of the valve cover as original, should this be sufficient? I haven't noticed any problems yet but I haven't driven it much. I was thinking of possibly adding the system that was originally on the 740 with the little oil catch can that mounts to the block. Will my engine have the little tube that goes into the oil pan? What do you guys think?

No, the block casting doesn't have the boss for the drain tube. The breather box will bolt on but the oil return will be floating in space.

On my 76-block I drilled a little hole and tapped a fitting into the crankcase blockoff so now I vent from both crankcase and valve cover.

That will be ok for the vent. If you're planning to drain oil back into the crankcase, you should have a drain that doesn't see boost pressure, which is why the later engine used a drain that dipped down below the oil level in the sump.
