hehe.
not far off.
noisy tappet is more likely to be a symptom of a worn cam, unless of course
it's a damaged rocker.
basically, once things start wearing, you'll find the cam and the rocker
shafts go first.
Check your exhaust manifolds though - I've known a small leak in a
manifold-head joint sound just like a buggered tappet.
as to changing 'em... well...
remove:
radiator/grille
Plenum and throttle body
rocker covers
inlet manifold
valley gasket,
front cover (timing cover),
timing chain and sprockets/gears,
rocker shafts,
pushrods,
tappets (valve followers)
camshaft.
replace:
camshaft
followers/tappets
pushrods
rocker shafts (making sure the pushrods all locate correctly both ends)
timing gears and chain, getting the timing right as you do it
front cover
valley gasket
inlet manifold
rocker covers
plenum and throttle body.
radiator
nothing very hard about it, 's an easy engine to work on. Just be careful
not to drop small parts down into the sump.
Not worth doing followers and not the cam, not a good idea to replace rocker
shafts and not rockers, although you can get away with it.
