The rear pinion seal is known to leak

Hapa- ''When I checked into my motel, I said to the lady at the desk:

"I hope the porn channel in my room is disabled."

"No," she said, "it's just regular porn, you sick bastard."

I don't know for sure, but it shouldn't be hard. From what i have read the pinion nut backs off and the seal pops loose. Doesn't sound hard to repair.

another very common leak is the rocker shaft o-ring on the side of the valve cover. is a very small leak but it works its way from the side of the valve cover to the back of the engine, then it works its way all the way down the motor until it crates a small leak on your garage floor. not easy to spot this leak, you have to look very carefully for it. it is part #16 in this diagram.

I have had this problem. Can't seem to get it to stop. The O-ring looks perfect. Slowed it down for a while with some RTV, but eventually came back
