Folks, last season on AVGAS I ran 11 psi and never saw this..
This year, I've set the boost to 12 psi and AVGAS. The only other mods is I have ran the air intake out the back of the sled (vs. under the seat) and jetted down 2.5 sizes on the main jets. The field that I am playing in is so small that it it only allows me to give it full throttle for about 3 seconds at the most. Pulled the sled in the garage and noticed that the filter that I have on the crankcase vent is moist with what appears to be antifreeze. Antifreeze level is fine, and I checked the compression and it's equal@210psi across the cylinders.
I assume the best thing to do now is crank the boost back to 11psi and just keep a eye on things?
Thanks

Have you check all your other areas...like the antifreeze line to the carbs? Did it come from that?

It looks like it's coming directly from the vent Brett.
