Question about Honda 8 HP Engine
I have a honda 8hp ohv,it builds pressure in the crankcase fast. when the oil is opened even when off after running, it blows all the oil ot with alot of force!what could be causing this the engine has only had abot 15 tanks of gas throgh it.
Is the oil over full ??? then i would suspect a crankcase breather issue which should be in the valve cover... then I would be looking at a head gasket issue, rings or all of the above

SOURCE: pressure washer stalls
Pressure washers work under very dirty conditions, no wonder they encounter engine problems. Here are a few pointers from a former pressure pump tech. The unloader is a source of engine overloading however this can easily be checked with a pressure guage attached to the gun with a tee fitting having the guage and the normal tip used for the unit. The pressure should never rise over rated pressure. The pressure should drop considrably when trigger is released. The life of the pump and engine can be increased by setting max pressure to 75% of rating. Most engine problems are from following conditions:
Leaking or misadjusted valves; clogged muffer /spark arrester; weak spark coil that is about to fail completely; kill switch/oil sensor wiring and or sensor mal function; gas cap not venting properly causing vacuum in tank and wet or dirty air filter.
All these problems easy to check, fastest repair is to disconnect oil sensor wire to check oil safety system. Then temp replace coil with known good coil. Loosen muffer bolts to check for clogged muffler. Temp run engine without gas cap to check for vacuum. Finally if everything fails, run the engine with carb cleaner spraying directly into the intake. If the engine continues to run with carb cleaner then the problem is fuel delivey and faulty carb. enjoy

It is possible that the oil pressure switch is not functioning properly or you have a lighter oil in the machine than is recommended.
Post a comment if you need more assistance.

Your carberator has crud, or rust, or glaze in it. The carberator will have to be removed, soaked in cleaner for three hours and then rebuilt using the proper carberator kit from any auto parts store. If you need to hire this done expect to pay about 35 dollars.

That engine requires a separate gas and oil. There is an oil sump with oil level needle and cap on the side of the engine. This is where you fill it with special pressure washer pump oil available from any good outdoor store or place where pressure washers are sold. As for gas, Unleaded or Premium unleaded gas will work fine. Try not to use any fuel with ethanol blends however. Here is a list of oils that will give you an idea what to buy for the oil reservoir: http://www.amazon.com/gp/redirect.html?ie=UTF8&location=http%3A%2F%2Fwww.amazon.com%2Fs%3Fie%3DUTF8%26ref%255F%3Dnb%255Fss%255Fgw%26field-keywords%3Dpressure%2520washer%2520pump%2520oil%26url%3Dsearch-alias%253Daps&tag=onlinetoolrev-20&linkCode=ur2&camp=1789&creative=390957
