Subject: JD 4440 Blow By

I noticed today that my 4440 with 10,065 HRS. was dripping a little oil out of the blow by. What do I need to expect? I was mowing roadsides, and some of it was at a pretty good slope. Not sure if that has anything to do with it or not. Had an underhaul on it about 500HRS ago. Other than that I don't think the engine has ever been opend up. Thanks

If its not using much oil I wouldnt worry about it. Everything I own has some blow by but never seen a problem.

I'd agree with commisioner and would monitor the oil usage, ours has 16K on it with out an oh, has some blowby, but uses very little if any oil on a 100 hour change interval!! good luck

Unless it's using large amounts of oil, starting hard, or becoming unreliable I wouldn't worry. If I am remembering correctly the 4440s had an air pump to push fresh air through the crankcase like they used on the new generation tractors. I wouldn't be worried about the oil coming out of the tube, that happens on occasion just from the amount of blow by and how much oil gets splashed toward the baffle, etc.
