"At first I thought it was the thermostat as this happened a few years back...replaced this, as it was indeed stuck open, but developed the same symptoms-fuel in the crankcase oil.

It ran fine for a day, then only at slow speed, as i limped home. Now I could sure use some advice on the proper diagnosis.

What could be the other causes for fuel in the crankcase oil?

Any advice would be much appreciated !"
 
I am having the same problem w

I am having the same problem with my bf8 I discovered the pcv was picking up the oil and gas mix from the crankcase and shooting it back into the intake causing the plugs to get wet with the mix. I took it apart and the pcv reed valve was rusted and possably not working properly. Just ordred the parts to replace ill let you know what happens. I know this does not explain the gas in the oil to start with. I was wondering if the fuel pump could be leaking into the valve cover. Does yours run fine then start smoking right before the plugs get wet? B

"I changed the plugs and they looked fine, though there is some white smoke at idle. This was ocurring before I had fuel in the oil.

Took a look at fuel pump and not the problem. No fuel came out when I primed it with the bulb. Just wondering what carburetor problems could cause fuel in the oil ?
 
"so if it is the fuel pump....

"so if it is the fuel pump....when i take the pump off and prime the bulb, fuel should come out, if it is faulty, yes?"
 
Do you think I need try to rep

Do you think I need try to replace the whole pump or start with just the diaphragm ? Can something go wrong with them other than the diaphragm? I'm a commercial fisherman and am trying not to have too much downtime ! Thank you kindly for your advice !
