i have 07 xrs brought to shop asked to get rave knives cleaned when i got my sled back went riding took a climb(big loss in power) noticed oil leaking from raves so went down on further inspection it seems the mechanic misaligned the gasket between the rave housing and the cylinder jug(man was i mad what a brutal mechanic lessoned learned i will do all my work on my own sled from now on) so went ahead and aligned it myself tightened it but was wondering should i replace the gasket. do you think having the misaligned gasket and riding that day like that would have done any engine damage
