2000 OX66 225hp white smoke rough idle

[Jessi'shusband]

Motor has been running good, went last week to Tenkiller and it was idling a little rough and it seemed to be putting out a lot more white smoke than normal. Top speed was about 2mph slower than normal. I have always ran ring free and non ethanol gas. Thinking maybe a fouled plug? What do you guys think?

My first inclination is your engine oil tank overflowed into the air intake cover. There is a tube that runs from the oil tank to the air intake cover that dumps oil when the tank is over filled. Remove the cover and see if oil pours out of it. Report back.

The fuel pumps could be leaking as well. Loosen the screws and squeeze the primer bulb. Look for gas running down from behind them.

Brand new fuel pumps as May this year. I will look for the oil leak when I get home from work today! Thanks

the old rule of thumb is black smoke is too rich on fuel.
blue is burning oil,
and white smoke is water.
need to pull and look at plugs to see if you can see anything on them
