Lou is correct. You should give the Engine a good cleaning and try to verify where the Oil is coming from. If its been sitting, Gaskets and Seals can dry out. 

  

If you have oil on the drivers side of the pan and or engine it is not the rear main seal.

thank you, it does run good, no noise, needs a tune up and oil change, only had a couple weeks, the brakes are dead, so need to replace the master before I can drive and see how she really is. Maybe a bit of driving my slow down the leak.
thanks for the response.

Welcome to  the Site. Your Car is simply marking its Territory just like a Dog. These Seals leaked from the Day these Cars were new. It can be changed in the Car but You might want to check the rest of the Engine for any other Problems. Is it in running Condition? As far as the rear main Seal there are much improved replacements available. They don't always fix the Problem. Most of the Time its because they weren't installed correctly.

  

Hi, new to the forum and somewhat new to y-blocks, I just purchased a 1957 Fairlane 500, original 292 with I think 119k original miles. The rear seal is leaking and wondering how hard it will be to change with the motor still in the car or should I take it out. the car has been sitting for sometime and probably why the seal is leaking.

Any suggestions would be helpful. thank you and great site.
