Hi all my name Ricki and i just bought a 1994 t4 188k. so i'm in the process of changing the timing belt and the oil pump pulley bolt just came off in my hand no tools needed the bolt just seem to small maybe a m6. I can't feel any thread in the hole and the hole seems to big. I ordered a bolt and washers and helicoil kit just in case. has anyone had problems like this ?
