Ford Engine Bolt Torque Chart Bolt Torque Spec Chart for Ford Engines

These specs are for stock-type bolts with light engine oil applied to the threads and the underside of the bolt head. Moly and other lubes offer reduced friction and increased bolt tension, which will affect the torque figure. If you use after-market performance bolts like ARP's, you should follow the recommended torque specifications.

Drivers side, under the dash, to the right of the gas pedal. If you have dual control there is one on the passenger side also.

have a compression test done notorious 4 bad head gaskets

It really depends on what is failing. If the compressor is locking up internally, it may be caused by debris in the ac system, or the compressor may not be installed correctly.
Too much or too little freon, too much or too little oil, and so on.

On most models the compressor comes out from the bottom.

Here's what the shop manual states:

30 Nm (300 kg.cm, 22 lb.ft)+90°+Release all bolts + 30 Nm(300kg.cm, 22 lb.ft)+90° In this instance you don't have a 'Torque to Spec"... you have a "torque to YIELD' In this specification, initially torque the head bolts to 22 lb ft... then turn each and additional 90°, then loosen each and REDO to the same specification = 22 lb.ft)+90° (you're actually crushing the head gasket TWICE and stretching the head bolts TWICE.

hi the cylinderhead torque settings are
STAGE 1, 30Nm (22l bf ft)
STAGE 2, 50Nm ( 337 lb ft ),
STAGE 3, angle tighten another 90 degrees,
STAGE 4 angle tighten another 90 degrees

Cant help you with the cam bearing though sorry

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.
