I recently replaced the timing belt on my 2002 WRX sedan. During the install I stripped the bolt that goes into the tensioner into a bracket, which goes into the block. End result, I had to put in a new bracket (pn 13156AA062), which bolts into the block with two 8x55x20 bolts (pn 800708460).
On to my problem: one or both of those bolts seemed to have backed themselves out of the block, resulting in a vibrating timing belt tensioner and a broken timing belt cover.
Since I have the size (8x55x20, whatever that means) can I just go to a bolt supplier and buy a replacement instead of waiting for subaruparts or a dealer to fill my order? What about metal grade and thread sizing etc? I'd like to take care of this now and not have to wait 3-5 business days.
