What is causing my pressure washer engine to stop hard/suddenly?

It's a Kohler Courage XT-7 engine. I replaced a leaking oil pan gasket and torqued the bolts back in place. Filled it with 10w30 synthetic. I've checked the fuel line and the carburetor, which appear to be clean. Spark plug looks normal and is gapped correctly. I've replaced the water pump with a brand new one. When attached, the engine would start up but then quit when trying to build pressure. Seems to run longer from a cold start. I then removed the pump to see how the engine runs without a pump attached. Within a minute of running normally, it stopped HARD with a clunk. That can't be good and I have no idea what would cause it stop so suddenly. Is there internal damage to the engine?

Your engine is experiencing a heat seizure... the piston sticking in the cylinder as it expands under heat with poor lubrication.

Testimonial: "That sounds possible, however the engine specification is for Class SJ or higher 10w-30. I changed the oil and used 10w-30 Service Class SN synthetic oil, which is better than SJ. It's also filled to the correct level. Also, If I manually turn the crank when the engine is cold, nothing seems amiss. Could the rings be worn/damaged?"

Sounds like you have a real sick puppy on your hands since it will not even work properly with no load. Sure the carb is giving the engine enough gas?

Testimonial: "Drained the gas tank the other day, and checked the carb for deposits - It's clean and clear. Poor fuel flow wouldn't cause the motor to seize like it did today, though."

    When the engine "seized" were you able to turn it over? Remove plug and then try while still hot? I am as confused as you are about the clunk. Before they seize they run for sh-- and then just stop.

    I had been able to turn it over before while warm/hotish the other day, but after today's "clunk" I didn't want to start it again. It has an ignition switch so with it in the off position I can pull the start cord and feel the motor parts moving smoothly.

  • richie46 May 03, 2017

    So then it can't be seized since that is sort of a permanent thing. If you cannot spin the engine manually after it is hot and unexpectedly shuts down, then it has to be some sort of thermal/expansion issue. Are lubrication channels clear and functional?

I have a kohler courage xt-7 on a white push mower, oil is spiting out of the crank vent tube. Whats the fix ?


You need determine the cause of the problem first.

Is the crankcase oil overfilled? If so is it laiden with fuel? If so then you have fuel leak.

If the crankcase isn't overfilled is it cause by blow by pressure from a bad head gasket or cylinder wear?

Leaking transmission fluid


TRANSMISSION FLUID LEAKS,CAN BE FOUND AROUND PAN GASKET.CHECK PAN GASKET,IF IT LOOKS WET AND YOU SEE FLUID DRIPPING AROUND THE EDGE OF OIL PAN, REPLACE PAN GASKET, WHILE YOU REPLACING PAN GASKET REPLACE TRANSMISSION FILTER WHILE OIL PAN OFF.IF TRANSMISSION OIL PAN NOT LEAKING, CHECK TRANSMISSION OIL COOLER LINES GOING INTO RADIATOR YOU WILL LOOSE A LOT OF FLUID THERE ALSO TORQUE SHAFT SEAL WILL CAUSE HEAVY FLUID LEAK WHILE ENGINE RUNNING CHECK OIL COOLER LINES AND LOOK AT THE TORQUE AREA WHILE ENGINE RUNNING YOU WILL SEE FLUID POURING WHILE ENGINE RUNNING THE OIL PUMP PRESSURE WILL PUSH FLUID OUT AT THE LEAKING AREAS.

Riding mower engine loud and smoking.


take it to a reputable shop and have them check it over - courage engines had a problem when they first came out - the bolts in the cover plate were not torqued properly and when they come loose, the torque of the engine turning will crack the block - this should be a warranty condition if the block is cracked - just make sure the shop is a kohler warranty station
