Yanmar YM240D Hydraulic fluid in engine oil (is that possible)

[brads522]

Hi Everyone,

I posted a few years back, asking about the possibility of having diesel getting into the engine oil of a Yanmar YM240D. I listened, replaced the injector pump and injectors but the crank case continues to fill up. I changed the oil yesterday and got a good sniff and I think it may be hydraulic fluid getting into the crankcase instead of diesel. Is this possible?

Thanks!
