Hi all, I have a Case 850 crawler loader with the A301BD engine. The smoke is grey and is not constant. It only occurs after using for over an hour. I’ve attached photos of the engine. There appears to be engine oil slowly dripping down the starboard side. Any advice is appreciated, thank you. -Rob
looks like a valve cover leak
Dumb question where does the smoke come from?
It comes out from the exhaust pipe. There are no exhaust leaks that I have located. It is also random in nature, sometimes it happens when I’m on an incline and then goes away after a restart…
I ordered a new gasket and will investigate when it arrives
Is your machine turbo charged if so check turbo for leakage
It’s non-turbo
The oil was coming from the top of the valve covers. There are two rubber washer seals that the oil pipe sits on and they appear to be leaking. I pressure washed the engine compartment and have kept the hood and side panels off. After being run for a good amount of time this past week the smoke has not returned…
