I have the same problem with my 23hp kawijunk. What i have found is that when you tear down the engine you will find there is a bushing/bearing in the top of the crank case. If you look on the parts breakdown it doesnt show the bushing because kawasaki says the bushing is casted in to the block and cannot be removed. That is wrong it can be removed by pressing it out but you have to match it up with a bearing maker. I have found a part number on the internet that is PAP 40 20 p10 pl which is a INA bearing bushing but that bushing is for the bottom pan not the top bushing in the crank case. What i done was went to a local bearing dist. and found the bearing was made by INA but INA doesnt care a PAP 40 25 P10 which is what you need for the top. So i ordered a PAP 40 30 p10 and plan to have it cut down 5mm to be exact fit as origional. So if your engine is like mine the crank in mine was shot also. So the parts to fix yours will prolly be the same as mine. What you will need is a new sump pan gasket,bottom oil seal,top bushing,new crank. That should get you back in business if you dont plan on doing this work yourself it could get expensive at a shop with all the labor involved. Let me know if i can help.

Does leaking or burning oil cause a spun rod bearing?
Only if it all leaks out.

If it leaks coolant or the bearing is loose, it has failed.

Usual failures are coolant leaks, or a loose bearing.

Bearing on the compressor or from a point that you can't see. I would bet on the compressor though.
Where can a water pump leak come from on a 5.7 Chevy?
Right below the snout, there is a weap hold. When the bearing, and then seal, go south, this is where the water leaks.

How can you tell if the water pump is bad in a car?
The diaphragm breaks, and water leaks out the "weep" hole, assuming the belt is good, there is water in the system, and the thermostat isn't stuck closed. You usually get accompanying "bad bearing" noises, as the area around the pulley bearing overheats.
What if you put a new water pump and pulley and it leaks three months later?
It may have been defective or there was to much tension on the belt and it wiped the bearing out on the W/P shaft.
2005 Linc Nvgtr 70k miles no oil on stick clicking from oil pan area no leaks HELLLLP?
There is something internal to the engine that is causing it to burn oil if there are no leaks. Put oil in the engine. The clicking could be a bearing going out due to lack of lubrication, have it looked at by a mechanic right away.
How do you check if water pump works?
To the best of my knowledge, if the pulley is turning when the engine is running and there are no leaks from the water pump, it should be fine. A2: It shouldn't make a squealling sound , either. It can work passably and still have a bad bearing and/or seal. A bad bearing, though it may not leak, is a sign of imminent failure.

Almost always leaks because the bearing is going.
2007 kawasaki bayou 250 carb overflow tube leaks?
not a bayou but my ninja 250 over flow tube was leaking and i replaced te two o-rings on either side due to cracks and no more leaks. i had to get them from the dealer because i couldn't find them at a parts store. they were like 4.00 each but had to have them. the o-rings for the fuel rail i found at Orileys though.
