I'm getting everything together for my cam swap while Im in there im going to change the o ring cause my oil pressure is alittle off right now from the last cam swap and o ring that was installed.

What color o ring will give menthe best oil psi? I remember reading about stacking them to get more psi but idk how safe that is.

Haven't heard of stacking them. The clearance is so slight that I wouldn't think there was room

Good info:

I don't think it will fit with two orings If you don't damage the o-ring I would think it should seal fine.

You fit the oring to the pickup tube type, not necessarily the oil pump.

Thank you for that link Rick, has the part number and all the info I needed. And I wasn't planing on stacking them I just heard it somewhere and wanted to see if you guys had ever heard of it being done.

I think you are talking about stacking washers in the oil pump bypass valve under the spring to up the pressure.
