When my cam belt broke long ago, I took the car to a chopper shop for the fix as I was very unfamiliar with the process. I brought the new belt as well as the spacer kit. Installation went well. We examined the belt and where it tore apart the belt had been blistered by heat. This did not happen due to running but when the engine stopped, and like all gas engines they have a tendency to stop at the exact same place due to compression differences. So the belt stopped at the exact same location on the crankshaft and got cooked. The spacer kit does help keep that area cooler but, more importantly, helps cool it off after running thereby saving the belt. I take off the cover during the oil changes and take a peek. I can detect that water has gotten in due to being caught out in the rain and a minor amount of dust and a minuscule amount of fibers from the belt itself. This belt has almost 30,000 miles on it and looks very good.
