So, my sons 2012 Canyon shredded a serpentine belt. I was surprised since it has only 52K on the clock, but figured "it happens" Had it towed to our shop and they found one of the bolts on the drivers side idler pulley was gone. They also noticed some oil leakage. Further investigation reveals the oil is ether coming from the main seal or oil pump. They will have to tear into it later today to figure out which. Are these engines prone to such an early failure? I'm inclined to believe the idler pully and oil leak are related. I5 engine. Thoughts?
