I had oil in mine from a defective vc that had a chunk missing out of it when i built my motor, oil got in there and I never cleaned it out. I Just blew my hg and now I am going to clean everything. But the oil in that sensor was the misfire cause on my buddies car.
My final tq is 90, I would not go past that because its pushing it. Follow the torqe spec sequence others are saying. I went 20/30/50/60/80/90 thats what slo2gen told me.
