3000W Chinese Gensets Info.

Yup, I agree. I knew it was not normal, but when I buy something cheap, I expect to get what I paid for! I purchased the PowerWise locally at 'checker auto'. I went back to the store and talked to them about exchanging it for a new one as I was still within the stores 90 day exchange time frame. Only problem was, they were already discontinuing it, only had one left in the store, and that one had a puddle of oil underneath it also. So I choose to just keep the one I had and worry about fixing it after it really broke. I do change the oil every other time I take it to the track. Have to admit, I never thought of just pulling the breather hose out of the airbox and let it vent. I'll have to do that and give it a good sea foam bath at the end of the season.

I talked to the distributer, DuroPower. They claim this is not normal & are sending me another generator. If the next one does the same thing, I'll have to assume that's the nature of this beast & deal with it. I will let the breather vent to the atmosphere so it will not foul the engine & filter. This may not make the EPA happy, but the engine & I will be! Not only will the spark plug get carbon on it, I guarantee the intake valve will have large carbon deposits on the bottom side as well. This will take a noticable toll on performance over time. It could also lead to an increase in the compression ratio if enough carbon builds up in the combustion chamber, which will lead to detonation & a burned piston. At that point the engine will be trash. If you're going to continue using yours as is, I would recommed changing the oil often, as this blowby is contaminating the crankcase. I will let you know the outcome when I get the new unit.
