Just bought a well used 2500 with 6,800 hours on the clock. Guy said it had a bad engine but it did run and drive when I tested it and it billowed white smoke. I found oil in the water and a disconnected fan switch. A compression test yielded 160 psi in one cylinder and 240 psi in the other. I put 15 psi in the cooling system and it dropped to zero in 30 seconds. I removed the spark plugs and put 100 psi of air into each spark plug hole and coolant few out of the uncapped radiator. So I figured I had two bad head gaskets.
I took the heads of the engine and found two bad head gaskets. Cleaned them up, checked for cracks, found none and reassembled with new genuine Kawasaki head gaskets. Started engine and it ran well but smoked constantly at idle and at full throttle. Comprression test now yielded 240 psi and 245 psi which is higher than I have ever seen in any gasoline engine I have ever tested. I put 100 psi into each spark plug hole and no water or air bubbled out of the open radiator cap. When I put 15 psi into the cooling system it held pressure. Also fixed the fan switch connection and installed a digital temperature guage so I know exactly what temperature the engine is seeing and that the thermostat and cooling system is functioning properly.
The engine smokes like it is worn out and needs overbored but with those great compression numbers it is had to believe. I am ready to pull the engine and tear it down but thought I would post to this forum before I did.
This is my first Mule. I only paid $800 for it and might decide to just part it out depending what I find inside the engine. Brakes are good, trans works fine and there is almost no rust anywhere.
Any advice will be greatly appreciated.
I have changed pistons in my engine now and is done, head is on place and everything.
BUT now i saw in the joyner service manual that it was important that the connecting rods was installed "the right way" (D. When installing piston and connecting rod assembly into cylinders. The marked surfaces of the
connecting rod and piston must face the front of engine (fig.3-10).)
The pistons is correctly installed but when i installed the connecting rods i couldnt see any difference from side to side so i just put them back in and now one of them is "rotated" 180 degree if i looked at the texts on them.
So, does it matter? Is the manual a little bit "universal" or it is important? Has it to do with some oil lubrication? The only thing i noticed when i intstalled them was the bearing shell that has to be put back right so the notch goes in to the groove.
Anyone has any good answear to this?

Well, after a bad experience with repairs to our Trooper, Lloyd tore into the engine himself. We originally wanted to save time by hiring the engine rebuild out, but that bit us square in the butt. Remember the discussion about Silverbullet motorsports in Yuma??
Stay tuned....we'll let you know what happens.
Has anyone rebuilt the engine in these troopers?
