bout a year ago, my truck broke a timing gear, the one on the crank. well i put newone on it and it broke again yesterday. both gears have discoloration like they got hot. why are these gears breaking?? any input will be appreciated.
 
if you unbolt the rocker arms and get the tension off of the cam does the cam spin freely? I've seen one that gaulded the cam journals and basically destroyed the cam and head. If the cam was trying to lock up in the head, it might break a chain or gear. thanks, roy
