Thought this may be useful to anyone who needs to do the rocker cover gaskets on their Thor V8.

So open the bonnet, and remove the plastic cover from the radiator:

Remove inlet piping, MAF, IACV etc – I removed the IACV by unbolting the 2 mounting bolts and hen removing the 1 hose fitting from the middle of the inlet plenum:

Remove throttle and cruise control cables:

Remove the 2 hoses and the electrical plug from back of throttle body - You would normally need to remove the water plumbing from this too, but it has already been bypassed on this car:

Remove vacuum and servo hoses, and unbolt the cable mount bracket for the cables:

Refit with new seal I put a tiny amount of loctite 518 sealant on the face of the heads too (also check for any wiring loom shielding damage):

Fit new loom shielding as required:

Remove water pipe from head – probably wise to have a new oring ready, and loosen the other pipe mounts – this will give it enough freedom -also remove alternator wiring:
