done this not long ago on the XE head
retrieve all the tappets and keep in order
for each one you need to get the hyrdaulic bit out the middle of the main body, i did this by whacking them on a hard flat surface
clean the body out with engine degreaser
clean the hydraulich bit with the ball bearing by imercing in degreaser and using a pointed object pumped it move the gunk out whilst still immersed.
put back together
place all in hot oil to let them fill up and any air will be expelled as it expands due to the hot oil
hope that helps
#Note# On later XE's the middle bit doesn't come out.
The 8v heads are different though, but remove cam, take the rockers off, take lifters out, follow hanyes manual of the how to. but on the 8v head you needa vlave srping compressor to get the cam out with out taking the head off.
I'm enquiring about XE
thers a how to by jamie f on cavweb 5id
our cav has one noisy lifter, i heard raggin it after a oil change can also cure itlmao, i like this way:P
outa curiosity, how much are new lifters?, anyone know off hand?

I am Neil, im 22, i have 2, one is longer then the other and one is more powerful, i know how to use them both.
all lifters should come apart ok - it's just a matter of whacking them hard enough to pop the piston out.
the later design ones may well be harder to remove, but they do come out - on some I doubt whether you'd do it by hand, I had to make up a special whacker tool to dismantle some ones out of an X20XE - Vauxhall use the same ones in pretty much any 20xe, Cnn or Xnn variant.
Maybe they all come out then
I tried soaking them for days and pulling the piston out with molegrips, they were completely freemoving but there seemed to be something solid stopping the piston coming out on all 16.
This was on one of the last redtops without a dizzy.
there is indeed a spring like clip up there, which needs to be compressed before the piston will drop out - I don't think this bit wears as such, so maybe they stiffened it up a bit later on.
what I did is turn up an alloy holder for the lifter, and insert a magnet in the top to hold it in, then bolt it to a long light bit of T section pressed steel about 2 feet long - which basically means you can whack it a darn sight harder than you can with your hand - also saves jarred wrists as well - pops them out a treat, no matter how well they seem to be stuck in there.
on the other end of the scale, I've seen lifters from an LET leave their pistons behind as you take them out the head.. I suspect there was some variation in this little spring design, as I can't see how it could possibly wear out tbh - it doesn't touch anything once the piston is popped in.
Are the tappets seperate from the camshaft area?
Would it be worth getting an aftermarket camshaft, like a Piper 270 for the XE, with followers & lifters ...the Piper Kit?
Also, if the aftermarket camshaft has been removed, and replaced back with standard camshaft, (and vice-versa) does the ECU need to remapped???
