On my car the tensioner broke off at 103K the belt was still in tact though. I had the belt replaced anyway since I had the thing taken apart. The mechanic said that the Ford manual said it was an interference engine and that I had most likely broken bent valves. I put it back on and started it up and it runs quiet and smooth with no perf lacking. I like to thinkit is non interference
