So I was on my way to doing this process to check the spacer. The car was idling and I was peering at the spacer with my head basically on the engine when I noticed a drop of oil running down from a spot on the underside of one of the fittings that screw into the sandwich plate.
I realized that it was possible that the threads from the fitting were the source of the leak and the oil was running into the crack around the sandwich plate/ spacer O-ring. When I did the original install my local auto parts shop was out of the "recommended" high temp thread sealant:
So I went to a hardware store and used another:
Both are oil resistant and rated for high psi and temps of 400 degrees+ so I figured I was fine. But now I'm thinking that the thread seal was the problem.
So I found a shop that had the recommended thread sealant and took everything the thing apart to redo the fittings.
When I talked to FBM they said some some customers over tightened the fittings and cracked the sandwich plate. I was relieved to see my sandwich plate looked alright
I cleaned all the threads with a wire bristle brush and cloth and reinstalled with the Peratex thread sealant. I'm going to give it a day or two to set, then I come back with results.
(The oil you can see on the sandwich plate came from the inside the filter when I screwed it back on)
