It appears to be the oil pump housing where this bolt screws in. The idler pulley #1 (the tensioner pulley) did come with a bracket but idler pulley #2 (more like a guide pulley) did not. We can't go with a larger bolt because it has to fit thru the center of the pulley then screws into the block or rather the oil pump housing. We're looking to try some JB Weld as a filler sorta like plumbers tape. What do ya think?
