Indeed so, but lifters do get worn (seen plenty on Opel engines), when 
their contact surface becomes scored od concave at all, and only those 
that have flat top surface, without any visible damage should be cleaned 
and reused. The job of inspecting, cleaning and priming takes time, and 
lifter set is relatively cheap, so routinely one would change the set 
instead. Saying that, I've cleaned many lifters on my own cars.

Support the MMO, but one would need to get MMO out of the system 
including the oil rad, which can be a messy job. Shorter oil change 
intervals, or o/filter change and top up every 5K, and oil every 10K 
(correct o/filter and grade of preferably synthetic oil), and keeping 
oil at good level just below the top mark can help a great deal.
