Hi,Mark, I think I have the bypass filter. The fitting is on the lower rear driver side of the block, comes out and tees to two oil lines. Small one to the oil pressure gauge, larger one to the oil filter on the manifold and then out of the filter and back to the block. On my cold start this morning the pressure showed up in about 3 sec. If I remember right, when I change the oil filter it takes about 20-30 sec. for pressure to show.
