Cylinder Head Bolts

Retain original position, clean and lubricate threads. With cylinder head removed screw bolts in finger tight. Measure between block face and underside of bolt.
Maximum bolt length = 97 mm.
Alternatively remove oil rail and screw the bolts in finger tight. If full lenght of thread engages, the bolt can be reused. If not measure between top face of oil rail and underside of bolt head.
Maximum bolt length = 378 mm.

          9 5 1 3 7
Front
          10 6 2 4 8

Stage 1 20nm
Stage 2 180 deg
Stage 3 180 deg
Would it be best to replace bolts anyway?

Well I would, because if you find the originals to be no good, then you've got another trip to the dealers.

The only down side is if they're after market ones, you could have the same problem as Mark.

At the moment I'm feeling as rough as buggery with a cold, but I'm dosing myself up so I don't forsee a problem ;D
If you do fancy coming up night before, we can burn the cold out with a beer and curry ;)

I personally still think, that the heater isn't working, because the water jacket is pressurising due to a blowing HG, causing airlocks and not enough coolant to reach there...

Are we changing the cam belt kit?

Although I've done a few of these, I'm no expert, but I still think HG. it's the only thing that ever goes wrong on these motors!!

Changing the cam belt is a bit of a pain in the arse because it means taking an engine mount off and supporting the engine, BUT I'm very pleased we're doing it, because it's well worth it while the heads off.

You may have to bring your jack - mine may have failed. I certainly do not want to trust it...

While we've got it apart, it makes sense to to the cambelt...
