Oil leak
Hello all,
I have noticed that when I park my car in the driveway, I get small oil leaks.
When parked flat, no leaks at all.I had my rear main seal replaced months ago.Any idea where this leak may be coming from? The leaks are in front,

Re: Oil leak
Leaking from from the front, I would say either the crank seal or oil pan. Possibly from the fuel pump, if you have a diaphragm pump and not electric.

Re: Oil leak
How many miles on the engine?? I have 175,000 and had a rebuild a couple years ago. Recently developed a leak that was covering the whole bottom end with oil. After cleaning it all up we discovered it was leaking around the harmonic balancer shaft. Removed it and placed a repair sleeve over the worn shaft and has been dry since. Apparently high mileage can cause a groove to be worn in the shaft and cause a leak.
This is just one possibilty. As jtsk stated, could also be oil pan. Or maybe timing chain cover...
