I honestly don't see the difficulty of changing the oil adapter gasket. It is a very easy straight forward job. drain radiator, remove wheel, remove oil filter, You can access the bolts through the holes in the frame, remove old gasket & install new one, then tighten stuff back up! You should be able to do this in an hour your first time around. You will need some misc. extensions & a swivel. I would like to know how much the dealer charges for this job? I've done a few for people & I charge $75 bucks + parts.
