Make sure that's what it really is!!! People love to diagnose any leak from the rear from the engine as a RMS when in actuality a valve cover, oil filter adapter, oil sender and oiil pan gasket leak are ALL gonna drip off from the RMS area cuz it's the lowest spot. Check it yourself.
I did mine a couple of days ago. It took all day, its not difficult just time consuming. Just check and double check and make sure everything is perfect and it won't leak. I was leaking a qaurt or more a week and now I leak nothing. Completely dry. It's like $60 DIY. Rear seal,pan gasket,oil, rtv sealent

I did valve cover, distributor and oil filter adapter. Easy to change. If it still leaks just don't change the oil pan gasket also change rear main. Guaranteed if u only change the oil pan gasket and it still leaks ur gonna be pissed off just to tear into it again.
