Pressure Washer --- Water in engine crankcase

Equipment in question: Generac Model 01675; Engine-Honda GC160

I get water in the engine crankcase whenever the machine is used. Where do I start?

I agree, it would have to be the seals between the pump and engine on the crank shaft.

I don't know how water could go from the pump through the solid coupling, around the crankshaft, and through the PTO seal to get into the engine. Doesn't make sense. That said, I can't think of any way water could transfer from the pump to the inside of the engine unless water is spraying on it from somewhere, maybe trickling down the breather hose into the valve cover or something like that.

Cheese,
I don't understand either. The first time it happened I thought the same thing but the next time I used the washer I was very careful to keep it upwind of where I was working & made sure there were no visible leaks at the machine. Guess I'll have to separate the pump from the engine & have a look.

michaeljp86, pretty much all gas pressure washers are made that way, however, water doesn't come into contact with the engine. Water would have to pass through the pressure washer valve body, into the pump crankcase, through the solid steel pump shaft or the shaft seal, and then if that were even possible, it would trickle out between the pump and engine.
