So for an update. I have a VERY BAD leak from my rear main seal. If I use paper towels I have to change it every 60 miles or so or it's saturated and starts to drip. If I use pig mat it goes about twice the distance. I'll be pulling the engine and replacing the seal this winter.I installed mine. The engine is girdled and it did have to be trimmed a little. Clears TA headers and crossover fine. It catches about 80% of the oil but I have some dripping off the starter. At least it’s not dripping on the crossover pipe anymore. The oil is originating either from the rear main seal, back of the pan gasket or back of the girdle. Everything above is bone dry. I’m using PIG Mat.
I have nothing on the crossover and no smell as long as I change my child's diaper frquently! I also have a spare that I won from Mike at the 3 bolt turbo challenge at RC's in May if anyone is interested in purchasing at a good price.
