Which means that the engine case was not designed to accept this type of
lifter. Installing them usually requires that the case be machined for them
to fit (lifter bores) amongst other things.

>(2) Hydraulic lifters not only wear out, like solids; they also fail.
They most often fail because it is very difficult to keep the oil of an
air/oil cooled engine clean. Even the smallest particle of dirt can clog a
hydraulic lifter. Going hydraulic means full flow oil filtration (a good
thing for engines that require it) and regular oil changes. In this case,
using fully synthetic oil is also a worthwhile idea, but if you have to
change your oil regularly (not every 20,000km as is possible with
synthetics) then this can also be expensive. But hey, it's only money.
Replacing a stuck hydraulic lifter means completely disassembling the
engine and probably also will require some other internal engine repair
work.

Purists Yكجظelf will hate me for saying this, but constant valve
adjusting is over-rated. I would rather check my tire (sorry, tyre)
pressure and wash my windows. Before I replaced my engine last summer, the
original had done 130,000 kilometers since it was rebuilt by the dealer in
the 1970's. I religiously checked the valves on this old engine (every
4,000 km) and the valves had never moved. I now have a mild engine, bigger
cam, bigger valves, swivel feet adjusters, etc. that has been driven
8,000km. I adjusted the valves and changed the oil after the 500km
break-in period. Since then, I have checked their position once (5,000km) -
no movement. I will now use my time to repair other things ... they are
not going anywhere. Expect a full report in two years after I have driven
50,000km.

True, that sound is pure Volkswagen. If you need a silent engine, buy a
new Cadilac. Any deviation from the "normal" valve train noise tells you
something is wrong. That goes for any engine related sounds.
