evening all..

doing some routine service work on m40 engined touring, trying to cure the slight tapping from top of engine, rocker cover off, inspecting the cam, cam looks perfect, so now for the tappets, how do i tell what tappet is making the ticking noise ?

also
water pump, and cam belt change, damn water pump is stuck in place, and stuck hard, will not budge ? any ideas is this a common problem ?

cheers guys

This is where theory and practice part company, will!
99 times out of a 100, the lugs will just break off.
Lots of violence and swearing is what's required for one that is well planted in. A big pair of stilsons on the body of the pump may get it rotating in the block if you're lucky.
A three foot length of garden hose, with one end stuck in my ear is my favourite for locating noises.

smashing advice chaps, many thanks

(But I always free it first by tapping it on the side of the pulley mounting until I see it move, then use the bolts...)

You must just be lucky then ive had a noght mare with all the M40 water pumps ive taken off. Normally involves a big hammer to get it out

tryed the stilsons. got it moving . but its still in and wont move out wards.
ill keep trying

the tappets i had tryed the screw driver but to not much luck .
but for the hydrolic tappets . how do you detect the correct "squish"

If you are taking the belt off anyway it's relatively quick and easy to take the cam out as well (don't mix up the order you remove things as they have to go back matching the same way) and take the lifters out. When they are fresh you should be able to squeeze them easily between finger and thumb to compress them. Close them up in a vice if they are tight (usually will be full of stale oil crud) and it should sort them out for another while.
