if ur a basic shadetree mechanic / turn a wrench..you can fix the leak/s yourself, giv'n you want to or have the tools
Oil leak can be from atop the motor, in the "valley". Climb up top and look down in the middle of motor with a flashlight. If oil is under the hpop/fuelbowl, then ur leak is from there..hpop...the non-servicable plug on the hpop which can be service, or an oring at the hpop line/s..also could be fuel, from the fuelbowl drain valve..notorious for that. If oil is under the turbo area, then more than likely the turbo pedestal is leaking...EBPV rod.
The oil then puddles up in the valley which then drains thru a small hole and into the bellhousing area, giving the look of a rear main seal leak.
The tranny could be just the vent tube clogged causing the leak. Inspect it, and see.
Do some googling, and you'll get stepxstep instructions for pretty much everything. Once you start removing the IC pipes and spider assy, thee entire engine bay opens up. Not intimidating at all, pretty easy to wrench on these things.
