mag side rod went through the bottom cases and broke the waterpump also
Need an engine or bottom end. Does anyone have parts for me?
 
No, but curious about what happened. I've got the same sled, I blew a piston at 4600 miles and found a broke exhaust valve on the good side. How many miles was on yours?
 
69 miles away from 10,000
Got a new motor and the bolt came out of the pro side exhaust valve 75 miles away from the truck and it heated up too much which took out the piston and cylinder.
If you can’t get over 7000-7200 don’t push it to hard or she’ll shit the bed
 
mine $$$ :(

New motor in mine with 1200 miles on it if your interested $9000
 
Nice sled I bet, but I'll keep pouring $$$ into mine. Eventually it will fill up, at least for a couple seasons I hope. I paid $8500 in 2020 for this one.

Bolt came out of the valve and it dropped to the bottom causing a lot of heat to build up and I ended up putting new cylinders and pistons in it. That was 1500 bucks for parts
