About 3 months ago, I replaced my timing belt, cam seals, tensioner pulley, water pump, and the front main seal. I also replaced the head gasket, and valve cover gasket. The car has been running great and still is but I cannot seem to find this new oil leak. It presented itself a few days ago while driving in Palm Springs. I know for a fact the rear main seal needs to be replaced because it's leaking out the boot next to the slave cylinder. My question is, oil was making it all the way back to the cat and there was oil all over the place (Cross Member, Where the tranny meets the engine) but nothing noticeable from looking down the front of the engine. Is it possible this issue can be caused by a leaking oil pan or a oil sending unit as well or maybe even the oil filter area? I know this isn't much information but I will inspect the car this weekend and take pictures as well.
