Hi all, upon fixing up my new to me mustang for the lady to use, the idler pully boss on the timing cover snapped off. It popped off at about 10-15 ft-lbs. I guess its better that it's broken it in the garadge than broken down in the holland tunnel again... So anyways I tried to fix it, I haven't seen any write ups on how long this lasts with the washer trick. So day one is today, fixed, 123k on the car. I drilled and installed a thread coil M8-1.25. Installed new idler pully and torqued down to a little more than 20ft lbs. I took the broken boss piece and drilled out the threads and used it as a washer. Curious to see how long this lasts. Will be posting in wtb for a replacement timing cover just in case.
