NOTE - nothing in the manual under lifters / followers ..they are called "hydraulic valve tappets" in the manual ..very little written about them except, inspect for wear ..or replace. does not tell you how to inspect them.
as far as i know, if some of the lifters are already deflated beyond what is normal ..then they may be the ones that need replacing
in cars ive done in the past they are wider in diameter and you could take them apart by smacking them down on a piece of MDF so getting the two components of them to separate or you could compress them in a vice .
But as i know nothing about the type in yours, i suggest once back together you rotate each and every cam lobe set so pointing so that they are opening valves fully and leave for an hour, so compresses and drains the tappets and resets clearance that will be 8 positions. and may take some hours. you will be able to tell if each one is done by the loose shaky rockers when the valve is fully up.
then you also have the injectors to contend with. replace with.new copper washers, clean the seats or ream if carboned up etc
knobby has said here many times re-use the bolts
All the
