Truck still at the dealer they say it fixed I don't believe them we shall see wednesday morning
I gotta go with Bigg Ron on this one. The rear of the intake manifold leaks whether you use gaskets or silicone sealer on them. Then it runs down between the engine block & the trans bellhousing making it appear like it's the rear crank seal or the rear pan gasket/seal. That's about all that's left that they haven't tried to repair yet.Sounds to me like it could be leakng from the intake manifold, those neoprene gaskets are know to leak espically in the corners. I dont even use them, I use RTV and leave them out. Or possibly the valve cover gaskets, I just repaired my oil leak which was comming from the VC gaskets, thought I had a main seal leaking until I removed the cover and it was dry in there.
