Replacing an oil pan gasket on a car shouldn't be too difficult for you, say, about an hour or two. As long as you follow some simple guidelines, the leak should be eliminated. Improper tightening or seating of the gasket material can defeat the purpose of your work. Grab a Haynes manual, or a tech guide for your vehicle, and have it handy.

I would suggest tracking the oil leak to ensure that it's not your front seal on your crankshaft. The amount of oil that you describe sounds like a bit much for an undisturbed oil pan gasket.

The engine does have to be raised. The bolts are not easy to get to until the engine is lifted and the engine mount is removed. I'm doing this job right now and the book time is around 5 hours.

If you want to repair the oil pan I would also check lower engine mount for leaking oil and cracks in anti sway bar near fitting's. This due to engine mount is oil filled. OEM sway bar is made of tubular steel and they crack easy. Replacement sway bar is solid steel. Here's the kicker. When they pull the lower frame to service oil pan. The engine mount and sway bar are attached to that frame. A honest mechanic should only charge for parts ($35 for mount and $100 for sway bar) and maybe a extra hour. My mechanic did all in 5 hours. FYI gasket is only $35 bucks. Good luck
