Im about to give this retorquing of the headbolts a try on my 7MGE and i had a couple of questions for CRE and/or Steves 86 Supra

The order for tightening...... The link Cre gave has an order for removing the bolts and then further along it has a different order for putting them in, im presuming that i use the order for putting them in to tighten them up? The one that starts in the centre of the block and works out?

Also, Steves 86 supra, you mention a drain bung in the block on the turbo motor? I presume my non turbo motor will have the same bung? I presume the risk here is that if you dont drop the coolant there is potential for the coolant to bypass the gasket and get into the engine during the retorquing process? At the moment im just getting a little pressurised gas into the cooling system but no water back into the engine and def no water and oil mixing. Ill have a look and see if i can find the bung.

Think thats about it, all i need now is a torque wrench!
