Ah hah,
I fixed it a couple days ago....when I put the turbo kit in I had to tap into that part of the oil system to put the oil feed line for the turbo. Well, the kit I used (Mosselman) uses a steel braided hose and it was pinching the little oil pressure sensor hose against the oil filter housing.

A little re-routing and presto. I'm just glad it was a cheap fixer. Thanks again Duke.
