Dewalt power washer has gas coming from the oil entry
I have a Dewalt power washer that is about 4 yrs old. I went to check the oil and gas spews out of both places where I usually add oil. It comes out pouring really fast to where I can see the level in the gas tank drop. Nothing I do stops it.

On my way back to look at it again. Thanks for the response. I'm a bit new at repair but the gas really flows from both of the oil fill tubes. Not a trickle. The unit worked fine last year before I put it away. It only sat during the winter. It's a Honda GX 200 6.5
Note front and back dipstick. Black and white plugs below the crankshaft. It is an OHV engine. If it worked fine last time, then I doubt the head gasket is broken. Might have disintegrated over the winter though.

I would gently but firmly tap the carb bowl with a medium screwdriver to see if the float loosens up and stops the overflow. Next would be to remove the bowl and take a look. A blocked vent would make fuel overflow too.

Bolt on side is for winter draining. Bolt on bottom is for removing the bowl. Be prepared to replace bowl gasket if it leaks after reinstalling it.

Once you have drained the crankcase of the explosive mixture, try to top up with oil and turn the enginr as much as possible to lubricate bearings etc. The fuel will do a wonderful job of cleaning all the surfaces of oil leaving them dry, unprotected and prone to rust. Bearings should never be dry, much damage can happen trying to start the motor unless you can get the pump to force some oil into the crank bearings and other moving parts.
The oil/fuel mix you are dumping is good for lighting bonfires.

I forgot about that. : D
The carburetor needs to be serviced / rebuilt with new float seal / rubber diaphram.
And the crankcase must be drained of all oil / gasoline then refilled with the correct oil.
Once the carburetor parts and the oil have been changed and because gasoline has entered the oil system I recommend removing the spark plugs and turning over the engine several times then wait an hour and turn it over again to remove any gasoline fumes (that may cause explosion in the crankcase) before replacing spark plugs and starting it.
If you do not have the required skills to do this then seek a mechanics service as a gasoline oil mix can more than light a bonfire ... it is a coctail for a nasty explosion.

These are great suggestions and I have moderate skills so it will be a challenge. I will be by the powerwasher tomorrow, Friday to try these suggestions and report here.
Thank you so much

Have fun. : D
oh, one more thought. Once you have it running again, You might want to seriously think about changing the oil a second time, after it has run awhile.
The gas/oil residue coating everything, might mess up the new oil as it is "flushing" out the insides. It depends on how bad it was.
Just keep an eye on the oil, to make sure it isn't "getting thin", or starting to get a gas smell.

The gasoline will evaporate from the crankcase during the oil change and fumes will leave the engine due to "turning over the engine several times then wait an hour and turn it over again to remove any gasoline fumes" that I suggested in my previous post.
There is no need to change the oil twice as suggested by coral47.
If you have no carburetor overhaul experience then seek a mechanics service.
You may be over your head if you think that carburetor overhaul is simple...
Depending on the carburetor type there are main and idle jets that may need cleaning also numerous other points to consider for correct carburetor performance (tuning).

Probably you have not run the engine with gasoline spewing from the crankcase ... as a fire or wose would result.
This means that no gasoline has entered the oil pump or bearings and thus not require a second oil change.

There may be doubt, but a litre of oil will be a lot cheaper than a new engine.
Thank you much. : )
