I have a 2016 Polaris Axys 800 RMK with TSS Turbo running on 50/50 race/prem gas. I recently blew or thought I blew a head gasket recently. My turbo got a vacume line hole in it causing my air/fuel ratio to get thrown off whuch in turn caused a bad DET issue. I pulled plugs and noticed coolant/water on the plugs, plus my coolant tank was bubbling after being ran. So I just replaced all the head Gaskets/O-rings and went up to try it out. I fixed my DET issue but my coolant tank was still bubbling after being ran hard. NOTE: The coolant tank would only bubble after sled was shut off for a couple minutes and the engine heated up with no coolant circulation. As long as the engine was running it wouldn't do it. I'm also not losing any coolant which stumps me on the whole issue. All I know is that it never did it before, and I can't figure out what is causing it to happen. The only other thing I can think of is when I drained the coolant for the head gasket swap, I never got the coolant bled all the way. But the engine doesn't heat up when running, which generally means air in coolant. My next thing was draining all the coolant and replacing with new. Any ideas/Info on this would be great, I'm at a total loss and am open to all suggestions?
