Post Mortem Pulling head - what comes off?

[carl johansson]

Ok guys,
So i now have to pull the head and do a post mortem, try to figure out why a new HG - Toyota OEM, would fail after less than 5 hours.

I have no idea, but i did farm out the job to a trusted mechanic - but maybe he made a mistake, so now I need to do it myself!

So to get the head off, what bits and parts come off - specifically in the intakes and manifolds. The FSM is a bit unclear at least to me, so on the exhaust side - would you pull off the header from the head? or disconnect it at the collector? or both?

As for the intake - would you take that off in 2 parts, or the whole thing at once? I assume you have to pull off the 1st part. over the top of the head, to get at the head bolts, but what about the part that wraps around the side of the head? pull it as one - or seperately? - what works best!
