Since i have had my clutch updated (08 450X) i have noticed that i have lost a little oil since my last oil change. It is not burning it but what i did notice was a dark residue in my antifreeze overflow tank. I can't tell exactly what it is but my guess is oil.
Has anyone had this problem? I know when they did the update i am the one that had to put the new side case on (was on back order) and when they gave me my quad back it was in pieces. Everything went back together fairly easy except we had to use the old seals for the water pump!! Could the oil be bypassing the seal allowing it to accumulate in my cooling system? I drained the antifreeze and it seems to have a darker tint to it than i remember and i know there are no oil leaks anywhere so this has led me to my conclusion of oil in the antifreeze!!

Any info or thoughts on this would be great!!!
Thanx, Nate
