John Deere 325 oil leak
I've got a ten-year-old 325 with about 600 hours on it. It's been pretty well maintained and runs well.... except that I just discovered that oil is oozing from a spot a few inches behind the oil filter (towards the driver, left side of the engine compartment. I'm not a mechanic, and don't know the name of this particular part. The oil is coming from just above a metal part that looks like it can be tightened with a wrench. I've done this, but it hasn't helped. Just above the leaky spot (at the top of this assembly) is where an electrical wire is attached. Can anyone tell from this description what the source of the leak is (a gasket?), and how difficult/expensive the repair might be?
