    2002 bugeye sedan, sheared bolts on timing belt tensioner bracket

    I recently had a really bad ticking sound coming from under my timing belt cover after a timing belt replacement, so I removed all the covers and found something very unfortunate. Apparently my timing belt tensioner bracket sheared the heads off the two bolts that mount it to the block. Fortunately, I do not think the timing belt skipped, since the tensioner had been held in place by the covers.

    Has anyone heard of these bolts shearing off? Even if I can extract them from the block, is that likely to happen again?

    How much time passed before the problem popped up? I am wondering if they were over-torqued.

    The ticking started happening about two months after I replaced the bracket and timing belt. I'm usually precise with my torque wrench, but I don't think I was able to find the torque specs on these two bolts, since they aren't a part of the normal belt replacement procedure.

    I know the bracket was upgraded (from 13156AA061 to 13156AA062) per this TSB:

    I installed the new style bracket with the old bolts, and I'm wondering if the old bolts were too short. The TSB doesn't say anything about updating the bolts for DOHC, only SOHC though.
