So I went through with the relocation kit, and I got everything connected, no leaking, I got an adapter to accept the sender unit and put that back on the block plate. Now, when the car is cold, everything's fine, but when the car gets up to temp, all of a sudden the oil pressure gauge on the dash drops to where the needle is just slightly above the L and the light comes on.
My first thought was that the high flow FRAM HP8 filter was allowing too much flow and not creating enough pressure so I replaced it with the STP 8873 (compatibility chart said it would work); and it does indeed fit, but still no pressure.
Has anyone seen this issue?
I'm going to get an oil pressure tester today and check out what the actual numbers are because it feels like I can feel flow in the lines.
My other thought is that the sender could be bad now from having it out and playing around with it.
