Installation instructions:
- Remove original oil pump bypass bolt and washer from the top of the oil pump. Make sure that the spring and plunger stay inside the pump and that they move freely in the bore.
- Clean new adjustable bypass.
- Install new adjustable bypass in oil pump using a 22mm wrench (7/8" will also work). Make sure the new copper washer is installed between oil pump and new adjustable bypass.
- Start engine and inspect for oil leaks.
Adjustment:
The adjustable bypass is designed to increase oil pressure. This part will not decrease the factory oil pressure. LC Engineering recommends adjusting your oil pressure to get a minimum of 10psi per 1,000 rpm. For example if you run your engine to 7,000 rpm you will need at least 70psi oil pressure. Do not adjust too much oil pressure into your engine; there is no need to run 90-100psi in your 22R/RE engine.
- To increase oil pressure, loosen the 15mm nylock jam nut while holding the 5mm allen screw in place.
- Adjust the allen screw 1 full turn clockwise and then tighten 15mm jam nut while holding the allen screw in place.
- Test oil pressure and re-adjust as needed

Excellent product!!
I was not able to find a high pressure oil pump anywhere and found this adjustable oil pump bypass from LCE!! Shipping was fast and product was easy to install and works amazing. I was able to bump up my oil pressure at idle and for my needs it actually was better than getting the high pressure oil pump. I highly recommend this product by LCE!!

Product 20R/22R/22RE/22RTE Adjustable Oil Pump Byp
This works great. I was having low oil pressure on the new motor at low rpms. This allows you to adjust the pressure with just a couple of turns of the Allen wrench. Super happy with it and easy to install.

Genius
I'll be buying one for every rig I have. I'd say it's a must if building for a turbo.

It does increase oil pressure
This part will definitely increase your oil pressure across the board. I’m very pleased with how it functions and how easy it was to install and adjust the oil pressure.
