Yes there is an order and they are both torque then angle tightened (They are stretch bolts).

If you don't get any luck from anyone today I'll have a look at home late tonight when I get chance.

 

It also depends on which gasket you are using.
Standard or MLS with shim type torque settings are 20Nm,180 degrees,180 degrees
MLS type without shim layer is 20Nm,180 degrees,135 degrees

 

The tightening sequence is on this page:

How do you put an angle on the bolt? Thought they were straight up n down?

 

You tighten the bolt through that many degrees. So 180 degrees would be half a turn, 90 degrees is a quarter turn and so on.

 

So you do then torque setting and then another half turn? is that what you mean?

 

Yep, so on the standard or MLS with shim it's torque to 20nm in the correct tightening sequence, then 180 degrees in the right sequence, then another 180 degrees in the right sequence.

 

Cheers mate, makes a lot more sense now! But it doesn't matter when your taking the head off which order you undo the bolts in?

 

I think you are meant to do them in the opposite order to tightening.

 

yep i think its this but only do half or quarter a turn on each bolt (i can't remember which one it is lol) till they are loose enough to undo by hand don't undo one bolt at a time needs to be in the reverse sequence

 

In my experience and as advised by many manufactures and k series experts it is better to do 20 nm 90*90*90*90 longer but helps the gasket and head seat more evenly

 

2 x 180 was used at Powertrain, and is what is specified in the Rover engine overhaul manual.

It is debateable whether it really makes any difference using 4 x 90 as opposed to the usual 2 x 180,; which method you use is really down to your own preference.

 

Probably use 2x180 cause am a lazy ba*tard
