Before you remove the timing belt - take out the plugs and use the 20mm socket
to rotate the engine. Start at #1 and work down the firing order - with #1 at
TDC, the valves are closed - push down gently on the lifters with something
made of wood or plastic. If there is more than 0.1mm slack before the valve
starts to open - replace the lifter. The documentation implies that lifters
can cheerfully be replaced singly.
The engine should be hot, BTW, (the fans should have run once at least) and it
should have run at 2500 rpm for at least two minutes.
