Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

That's the only way I can describe the way it looks. It's with my Little Wonder Leaf Blower with a 10hp Intex engine. I've seen this before but on a lawn tractor with an liquid cooled engine that had coolent leak into the engine but never on an air cooled engine. I did leave the blower outside (no choice during a remodeling job). I did cover the engine with an upside down plastic storage bin but there were times when it blew off and I didn't notice for a few days so it did get rained on. Could rainwater get into my engine. I changed the oil so hopefully it didn't do any damage.

Yep, you got water in the oil. Drain and refill it then run it for a few minutes. Change the oil again and you should be fine. The second oil change assures you got all the water -- cheap enough to do. Water probably got in through the carb.

Do you any explanation why the water is getting through the carb?  What can be done to eliminate it?

Definitely water, could have gotten in through the carb or muffler or even through the oil fill. Could even be from condensation from sitting in the sun. Wind could have blown it in.

Most likely got in through the muffler. Assuming the the engine had some type of air cleaner on it.

I would replace the spark plug after the second drain and fill.

Howdy-

My guess is the rainwater entered through the air filter>>to the crankcase vent fitting on the filter housing>>throught the vent tube into the crankcase. Water can get by the one way valve, if there is one in the vent. Also replace your spark plug.

Thanks for the replies. I changed the oil, ran it for a few moments just to warm up the oil, then changed it again. Seems fine. I'll pick up a new spark plug tomorrow.

I've had a similar problem when I submarined an atv. I changed the oil a few times and still had the milky residue. A mechanic I knew mentioned filling the crank case with diesel and draining it and then give it one more oil change. That did it. The diesel bonded better with the water so it took it all out.

Be sure not to start or try to start the engine with the crankcase full of diesel.
