The rear main seal, I'd say no because the transmission has to come out to do it. Unless it looses allot of oil after doing the oil pan and the valve covers I'd say just leave it until it gets worse.
I have a '97 3.0L vulcan that last year developed an oil leak. First I thought it was the oil pan and had that replaced for $400. The shop couldn't see it was the rear main at the time. I had the rear main replaced and it was about $1100 due to removing the tranny and virtually removing the engine. I suspect both were leaking anyway. I still have a slight valve cover leak but very minimal.
I'd say, if they can pin down which one it is, or both, you can make a more informed decision about whether its worth it to you.
Had I known I was in for these repairs plus some others, I probably would have dumped the car.
Since nothing has gone wrong since September (fingers crossed) I feel better about the decision. At least it conforms to my philosophy that repairs like this are cyclical.
