ID:	333444 New ski 2012 Rxp 260 RS , walked 47 hours collapsed piston,connecting rod,and the neck of the crankshaft . replaced the crankshaft ,a connecting rod,a piston,oil pumps ,the heat exchanger, and sleeve one cylinder. but that's only an hour passed with a small ,blew a gasket coolant left in the body. take that watch repeats the trouble . what could be causing this ??? head on my shoulders broke already . Your opinion friends ?

    somebody tell me? clearance piston cylinder was placed on a manual! Unlike oil-starvation?

    I'm no expert but it looks like your piston slammed into the valves.

    was the head gasket failure at the cilinder you resleeved????? it could be that your new sleeve has moved down a little because of the heat cicle.

    A leaky head gasket would have caused the coolant to get into the cyl & cause a head gasket failure. But the Only way the valves hit the piston is the Rod brg failed too. OR the Cam is Not in time with the Crank. Remember... If the rod gets bent the Stroke (rod) become shorter.. If the Rod brg fails the Crank can throw the piston into the valves cause Now it can travel too high up into the cyl.. That engine is going to have to Come completely apart to resolve all the problems it has.. p.s. about 99.9 percent of the time the Original failure on #1 cyl is water related. The intake is Hugh & can store water you are not aware of from a earlier dunking...... the super charger will blow across this water untill it is back to FULL Power & It will pick up the water and move it into the intake of the head. Due to the engine tilted being down in the rear the water is normaly in the rear of the intake manifold waiting to go into #1 cyl. Even if you have a leaky intercooler or a external cooler. 99.9 percent of the time the water is in the rear of the intake manifold waiting to come into the #1 cyl intake port.. looks like the problem repeated itself.. IF YOU Only have valve strike on #1 cyl & the other cylinders are Good?? I would check the rod brgs on that #1 cyl & measure the Crank journal too. To make sure a set of std brgs did not get put onto a crank journal that maybe be undersized? Either way you going to pull it back out & disassemble the entire engine to check the crank and replace the brgs...

    How are the cylinders numbered on these skis? #1 is in the front (bow) and #3 is in the rear (stern)?

    #1 cyl is your closest cyl to the Rear of Engine or the Flywheel End- Timing chain End of the Engine & it is Marked on top of your Valve Cover.. Remove the Oil filter & look round the outside of the filter. I think you will find metal in the outside of the oil filter...if you have a brg failure.. if you have valve strike Only On One cyl???? I believe you will find a problem on that crankshaft rod journal or that same cyl rod brgs....
