took the car in to get the oil changed the other day after the low oil light popped on and found that the oil pan gasket needs replaced. the shop said they basically needed to pull the motor to get the oil pan off and wanted to charge $500 in labor for a $30 part. i told them what they could do with that and found a different place to get my oil changed. but anyways, what's a good estimate for that? i really don't feel like doing it myself, nor do i think i have the tools for it, but the fact remains, it is leaking.
