Help me identify this 12H-T Oil Pump (1 Viewer)

Hi 60 Series lovers!

I have bought an Oil pump for Land Cruiser 60 series' 2H/12H-T recently.

Could you please have a look at these enclosed 2 pictures.

I have made a side-by-side comparison of the brand new Oil pump (the clearer, cleaner one in the picture) against the old one I have just removed from my 12H-T engine (the darker, dirtier one in the picture). I have noticed a slight difference that I am pointing my finger to in the pictures. My former Oil pump has a hole that the new one doesn't have. Any chance I get some guidance and advice, please before I make any risky replacement? Or should I just drill the same "hole" to the new?

Thanks in advance
Regards

Thanks, that's exactly what I am trying to understand. I am watching a youtube video right now on the replacement of the Oil pump, the old one has a hole the new one doesn't. Yet, the mechanics are still replacing it directly. Regards

its the hole for high oil pressure relief, in the new ones the pressure is being relieved internally so no problems there

Thanks a lot! I can now be happy with my recent purchase and future replacement

I couldn't get the oil pump gears in Nepal, so I replaced the whole housing like you. The oil pressure has definitely increased.

"The oil pressure has definitely increased.".... Is it a bad or good thing?
