I have an 89 raider 3.0 V6 that has an oil leak that appears to be coming from the rear oil pan area. It's fairly constant leaving a grapefruit sized puddle when I shut it off. Pressure is fine. One time I checked the bolts on oil pan and they were somewhat loose, so I tightend the ones I could reach. Couldn't get to the back ones. It helped some, but has returned. I'm also afraid it could be the rear main seal, don't know for sure. Question: what needs to be done and how diffacult would it be to change rear main seal and oil pan gasket? Thanks.
