I'm trying to remove the oil pan to replace a leaking rear main seal, having trouble.
I set the crank keyway to the 6 o'clock position, removed the motor mount thru bolts, starter & exhaust manifolds and loosened the 2 transmission mount bolts, then I jacked the motor up (On Harmonic balancer)until the trans hit the firewall, still can't get the pan out! I've done rear main seal jobs before on various GM's (And others) but not this year and model, anyone have an idea before I have to yank the engine?
