I have a aftermarket high pressure oil relief valve, when looking at it compared to the OEM it looks like same size piston, all holes look the same, etc...
But when comparing spring tension the OEM valve spring is a lot stiffer than the aftermarket.
I know there is more into the design of the aftermarket one than just spring pressure, but the pistons seem to be the same size.
Anyone else ever compare aftermarket valve against an OEM valve?
What pressure can I expect from a new AM oil valve?
And what valve is recommended?
Thanks.
