After a ten year break from snowmobiling I bought a 2006 600 RMK in October. I took it out for it's first real ride today, opened the hood after three miles and saw this?

I have no experience with the Liberty engine. Can anyone tell me what this is and if I have a problem? Any help is greatly appreciated.

Thanks in advance.

Rust has formed on your exhaust valve springs. And you had moisture trapped in the bellows. When you ran the sled the bellows opened and out shot the gunk. I would take them apart and clean them immediately. It's not the greatest design.

Rust. Looks like a combo of rust and a torn bellows, easy fix, just pull the 4 bolts to inspect it.

So I should just take it off, clean it up, and it will be good to go?

If you look at the hood just above the VES assembly, you will see a small weep hole that acts as a drain to drain water out of the headlight assembly. That hole is DIRECTLY over the hole in the VES valve on the MAG side. After you replace the spring and clean out the rust, to prevent this from happening again and again, plug the existing weep hole in the hood and drill one to the left or right so the water doesn't fall into the VES. I have a 2006 600, 2007 700, and 2008 600, all three have this issue.
