i dont think youre going to find a bolt diagram. the timing cover bolts are 10mm heads that are about inch long i guess. theres 4 10mm bolts that are about half an inch long that goes to the water pump pulley. theres 4 12mm bolts with the number "8" on the head that goes to the crank pulley. theres 3 12mm bolts that go to the a/c tensioner bracket. theres some long 14mm bolts that go to the motor mount and a 17mm nut that goes to the side of the motor mount. thers 2 14mm nuts that go to the other side of the motor mount. i hope that helped you out some. good luck
