No they are self adjusting. How bad is the clicking? That would
be an extremely rare condition.

Have you listened w/ a stethoscope to determine that the clicking
is exactly the lifters and not an exhaust leak. An exhaust leak at
the head sounds exactly like a clicking lifter.

The clicking under the hood on 944's is almost(almost)always the injectors firing. A sticky lifter will be worse in the morning, and usually quiet down as the car warms up. If you suspect the lifter try thinner oil next oil change. Also, you can get LUBRO MOLY slug remover. Use as directed to clean out the block/head etc. I have used the product and had great success with a sticky lifter in my fathers 928.
I have not torn down a twin cam car yet, so I can't tell you how hard it will be, a single cam car lifters can be replaced in a few hours. Problem is which lifter to replace. At 37.30 (928-105-312-02) you have 596.80 dollars worth of lifter to buy if you want to be sure to find the bad one.
