The torque settings for the big end (connecting rod) bolts on a 2008 Ford Transit 2.4L diesel engine are as follows:
Step 1: Torque the bolts to 25 Nm (18 lb-ft) using a torque wrench.
Step 2: Tighten the bolts an additional 90 degrees (1/4 turn) using a torque angle gauge.
Step 3: Tighten the bolts another 90 degrees (1/4 turn) using a torque angle gauge.
Note that these torque settings are for the standard size connecting rod bolts. If your engine has oversized or undersized bolts, you will need to consult the manufacturer's specifications for the correct torque settings.
Also, it's important to use a good quality torque wrench and torque angle gauge to ensure that the bolts are tightened to the correct specifications. Over-tightening or under-tightening the bolts can lead to engine damage or failure.
New cylinder head bolts coated with a sealant (such as GM 1052080).
Torque the bolts in the proper sequence (1-8) to 37 ft. lbs. (50 Nm).
Using a torque angle meter turn the bolts 90 degrees in the proper
sequence.
Left side exhaust manifold. Torque the bolts to 12 ft. lbs. (16 Nm).
Spark plugs. Torque the plugs 11 ft. lbs. (15 Nm).
Right side rear cylinder head:
Cylinder head bolt torque sequence-3.4L engine
New cylinder head gasket
Cylinder head on top of the gasket and make certain it is lined up properly with the dowel pins

sequence.
Right side exhaust manifold. Torque the bolts to 12 ft. lbs. (16 Nm).
Spark plugs. Torque the plugs 11 ft. lbs. (15 Nm).
Spark plug wires
Exhaust crossover pipe. Torque the fastener to 18 ft. lbs. (25 Nm).
Valve rocker arms and pushrods. Torque the fastener to 89 inch lbs. (10
Nm). Using a torque angle meter torque the fastener an additional 30
degrees.
Lower intake manifold. Torque the bolts to 115 inch lbs. (13 Nm).
Upper intake manifold. Torque the bolts to 18 ft. lbs. (25 Nm).
hi to tighten you have to do it in 4 stages as follows
1st stage 40nm leave 5 mins
2nd stage 60nm leave 5 mins
3rd stage 90 degrees leave 10 mins
4th stage 90 degrees
then you are done i will try put order on here i hope this works as follows

Use new bolts, tighten in the following stages
1. 20Nm
2. 100Nm
3. wait 3 mins
4. slacken bolts 1&2 retighten to 20Nm +110 degrees
5. carry out stage 4 for bolts 3,4,5 & 6
then bolts 7,8,9 &10
Sequence,8 4 1 5 97 3 2 6 10
Bolts 9 & 10 are flywheel side of the engine.
