How much is an oil pan gasket replacement?

There's an estimator on top of this website..

which eng and is it all wheel drive?

For the v6 engine its only 1 hour- 85.00 plus the parts- probably around 30 and an oil change- looking at the 250 range. If it is the larger v8 motor you are looking at the 5.8 hr range plus parts & oil change. I would love to help you!
