Thanks for taking the time to post details of your procedure.  I didnt know that you could dismantle these tappets because I was misled by the 'H' manual that said they cannot be dismantled!!

I have added a couple of my own suggestions here based on my experience so far.

To get the plunger out of the body, most of us would prefer not to use a hammer, so as an alternative that works, just tap the whole body sharply onto a flat block of wood a few times until the plunger is nearly out, then you can easily pull it out with your fingers or some pliers. 

When I got the plunger out, I didnt find much muck in there, but I noticed that if you look into the plunger (wash oil away in petrol first), there is a small ball bearing. If you depress this with a thick wire tool, a lot of sludgy oil comes out, and unless you do this, the sludge may be difficult to shift as the ball is spring loaded and seals the sludge inside.  Immerse the plunger ino some petrol, and pump the ball bearing a few times to clean it out.

Thanks again, and I hope my bit helps to improve the effectivenss of your procedure.

Nice guide!
I cleaned my lifters today with the help of this!
May I add,...If your against hitting the lifter with a hammer use a second piece of MDF on top as I did!

And when re-fitting them note that there is a small hole in the lifter (oil way) that according to the Haynes manual needs to line up(well NR as dame it) with the oil hole seen in the pics bellow!

if doing something like this for the first time what is the potential for damage/disaster. also how difficult is it to set the timing again

Tappets are easy man, it's the timing thats hard(er)

If you take your time and turn the engine over by hand when you're done, you dont run much risk of damage! Just give it 2 full rotations by hand, check the tensioner and you're sorted. If you want to start a thread as you go along im sure you'll get plenty of help and advice :)
