Cylinder heat bolt torque:
Torque sequence --------- front | 7 3 1 5 | | 8 4 2 6 | --------- Step 1: Torque all bolts in sequence to 14 Ft/Lbs Step 2: Torque all bolts in sequence to 29 Ft/Lbs Step 3: Torque all bolts in sequence to 36 Ft/Lbs Step 4: in the sequence, loosen the cylinder head bolts three turns. Step 5: Tighten short bolt to 15 - 32 Ft/Lbs Step 6: Tighten long bolt to 30 - 36 Ft/Lbs Step 7: Tighten all bolt to 175- 185 degree note: Do not loosen all of the cylinder head bolts at one time. Each cylinder head bolt must be loosened and the final tightening prior on the next bolt in the sequence.
Main bearing torque:
Torque sequence: Step 1: torque bolts to 91 Ft/Lbs with the exception of the rear main bearing cap Step 2: torque rear main bearing cap bolts to 88 Ft/Lbs Step 3: torque brace bolts to 40 Ft/Lbs Connecting rod torque: Torque sequence Step 1: Torque to 29 Ft/Lbs Step 2: Turn an additional 90 degrees
Torque new cylinder head bolts in sequence to 44 ft lb. Loosen bolts approximately two turns, then torque bolts in sequence to 44 ft lb. Turn bolts an additional 90 degrees in sequence, then an additional 90 degrees
2lt overhead cam with them horrible tappet adjusters,cast iron head but valves dont hit the head if the timing belt breaks ,but it does on the 1600 .called a pinto in america .Remember the assembly line well ,have many a fond memory of working on it and the staff canteen on night shift ,what lovely grub we got.Head bolt torque is about 80lbs because i used to pull them down to check them after the machine had tightened them up
Stage 1 = 15Nm Stage 2 = 40Nm Stage 3 = Plus 90 degrees or quarter of a turn. Good tip is to mark all the bolts after initial torque setting with tip-ex , i.e. all to the front of the car. When you finish they should all point towards the timing belt. This is also a good way to make sure you don't miss one or tighten one twice if you are distracted since it is not a torque setting. New bolts should be used by the way as they are stretch bolts. Timing of cams - remove cam cover and you will see a slot on the end of the cams. Opposite end from belt. You need to slip a piece of 5mm flat bar or a long 5mm allen key into then so that the bar rests on the face of the head. Engine should be a tdc. cheers John
