Thank you!
That's what I'm thinking. From the top it looked like the ring got hot and turned purple. I ordered pistons/gaskets and crank seals. I'm gonna pull the motor and tear it down. Hoping I see an obvious seal blown or something. I've never locked one up before so if you have any tips or things I should check while I have it apart, lemme know! Last thing I want to do is tear it down twice! HahaThe idling high sounds like a crank seal or possible air leak from somewhere. That would also explain how you were even able to baby it back. (Air leak slowly robbed that side of lub till she locked)
In my experience a cold seize/4 corner, stuck ring or high heat shuts it down right now. Then pop the hood and feel each side of the mono block and the one that’s screaming hot is the victim.
I don't have a fix kit. I've been running wiseco pro/axys pistons. I got about 120 hours on the stock pistons when I lost compression and rebuilt with the wisecos. I got about 140 hours on them before they locked up but recently did a compression check and had 138 psi in each hole. I definitely suspect an air leak but also don't know if an injector issue could have caused it. I already checked the power valve bellows and didn't find any tears. Seems like the pistons are free in the cylinder as you can wiggle them slightly but the rings don't want to move on the mag side.The most important thing is figuring out why if went down. At least to the point were your 99% sure you’ve found the answer. What the piston looks like can tell a lot about the story.
What pistons did u go with? Do you have the fix on this sled or not?
I hope you get it back together quick bud! Let us know what you find. I was pretty encouraged with the new mapping in my sled until I lost my lower pulley, gonna have a new one in a couple days and then do some more testing. There's still plenty of winter left!Yeah I'm at 260 hours total now. I purchased all the seals so I plan on replacing them all. I've had good luck with wiseco pistons in pretty much everything I own but maybe next time I rebuild my top end I may switch back to cast as it seems it's what everyone is recommending now. I'm super cautious on warm up and always let heat saturate before even unloading.

My sled was running awesome that day!I hope you get it back together quick bud! Let us know what you find.

What cast Pistons would you go with if you don't run Polaris Pistons? I run forged in most everything I own or vertex cast but I never seen vertex pro Pistons.
Last Weisco pro Pistons I bought were 82.00 each, when I asked about genuine Polaris Pistons at the dealer I was quoted 370.00 each.
Is their a chance your cylinder could still be good? Possibly you just have some piston aluminum transferred to the cylinder walls?
I guess you know about using muriatic acid?
I had my buddy's 11 assult monoblock cylinder done by FASTENTERPRISES their in Manitoba I think it was , they are a Canadian division of millenium and I was able to request an extra fine Finnish on the boars after discribeing Indy dans H7 finish. When Pistons and cylinders came back I took them into my local machinest to be measured/double checked 4995 was specked on the piston box and I had asked for 4995+ And 5000 max... I got it and it was a good looking job that held out even after losing a set of Pistons I was able to clean up the bores with acid and drop in new Pistons and run it. Ports were all chamfered nicely no complaints at all , for what it worth my stuff came back in a millenium tec box.
Any one else tryed Kelly at fast enterprises? It's better than CVTEC or monguse machine if you don't want to exchange Canadian funds to us funds
