If they're like mine adjusting them probably wont be enough. I thought they were fine until I compared them with a freshly ground one. They have a fairly definite point (like a cam) where they push on the valves, but they're meant to be evenly rounded.

Hi everyone,
Is this the same settings for the 97 2.8L turbo diesel?
Whats involved in removing the rocker cover with the vacuum pump i couldn't find the workshop manual?
I think its a lifer noise I,m hearing, but I,m also thinking it maybe a injector they can sound the same, she has only done 235,000 km i will check it out tomorrow to see if it the lifter or injector with the old screwdriver.

TB42 Tappet adjustment.
Adjusting Intake and Exhaust Valve Clearance
Adjustment should be made while engine is warm but not running
1. Set No. 1 cylinder at top dead centre on its compression stroke,(with timing marks aligned remove distributor cap the rotor button should be pointing at number 1 ignition lead position in reference to the distributor cap if its not rotate engine 360 degrease) and adjust valve clearances 1,2,3,6,7,10
2. Set No. 6 cylinder at top dead centre on its compression stroke, (with timing marks aligned remove distributor cap the rotor button should be pointing at number 6 ignition lead position in reference to the distributor cap if its not rotate engine 360 degrease) and adjust valve clearances 4,5,8,9,11,12
Valve clearance
Intake 1,3,5,7,9,11 - 0.38mm (0.015 in)
Exhaust 2,4,6,8,10,12 - 0.38mm (0.015 in)
Adjusting screw lock nuts - 16 - 22 Nm (1.6 - 2.2 kg/m, 12 - 16 ft/lb)
If you are running duel fuel it is a good idea to set your tappets 1 to 2 thou bigger in gap as LPG has a tendency to close up the gap.
Although this is a widely used practice its not an absolute necessity.
Cheers
Paul

I remember doing the Holden red motors, engine running, back off the rocker till it rattled, then close up till silent. Do all 12 and shut it down. The tighten them all 3/4 of a turn. Tappet cover back on and start up, once the lifters equalised, that was it.
