My 782 with the KT 17 Series II engine always seems to be pushing oil out somewhere on the engine as if the crankcase is pressurized and not breathing properly. I replaced the crankcase breather with the newer style valve sometime in 2016 so it's still pretty new, but even when new it pushed some oil out in places.

Last weekend I just degreased and cleaned the entire engine to get it ready for the mowing season. So last night, I mowed for a couple of hours and when I got done I lifted the hood and found my engine just covered in oil. I could see where it had pushed out oil around the governor shaft, from under the points cover, up through the breather tube and out from under the dome on the air cleaner, and even around the threads on the oil fill neck.

Do I just have a bad crankcase breather valve again? Or could there be something else going on? I lost so much oil last night that the oil on the dipstick was just barely in the safe zone after mowing, but was right on the full line before mowing. I have never lost that much oil that fast before. I did have a leaking rear main seal behind the PTO clutch last season that I replaced over the winter, so I don't know if that was easing some of the pressure from blowing oil out everywhere else I mentioned and now that that release is gone it's blowing out everywhere else or what. Any help/thoughts is/are appreciated?!?
