Block of BS oil hole with bearing or let the oil flow?!?!

[SnowBird]

Just rebuilding my engine and I currently have the bearing blocking the oil hole, and I keep hearing its good and bad. My pump is the OEM with 136K. My question is, should I leave it blocked off and port my oil relief valve, or should I unblock it and then risk the chance of pressure being too low? And I am running a catch can.

Unblocking is putting a hole in the oil galley. Port the pressure relief if your worried about too much oil pressure.

hypotetically lets say i messed up the inside surface of my block off bearing that wouldnt cause any ill effects since nothings going to be running on it i didnt mess up my bearing i took out and was thinking about just putting the old bearing back in and putting the hole so that its not over the oiling port

To avoid crazy oil pressure issues i use a stubshaft for the oil pump and leave the other shaft in with no belt. No balance shaft belt or bearing problems, and no 130psi of oil pressure. The best of both worlds.

Honestly, you should be replacing your oil pump if you're rebuilding your motor anyway. Cheap insurance, IMO.

why do you leave the shaft in that just sounds like a bad idea

It wont hurt anything its just sitting there! I know the next time I do a 4g63 I will leave the front shaft in and just order the stubby for the rear!

It's a couple pounds off the frontend of your car. Toss it.

Exactly thats what i did, get that excess weight out of there.

I just cut the shaft off and weld the hole shut.
