Is this the 12 valve motor? Should be hydraulic if so.

Unless you can see adjuster pegs and locknuts on the rockers it will be hydraulic. That engine was used in Telstars, 626, Bongos, Couriers etc and I don't recall any 12v having valve adjusters. They were however prone to lifter noise when they got old and/or were not maintained well enough, use of Magnatec or Proma additive generally sorted it.

its an old motor, and with adjustables they will be worn, your .3 feeler blade will be bridging the wear do you know how to adjust them when worn so you get the correct adjustment?
first put a .5 blade through and adjust to firm pinch, then put a 20 through and adjust again - but note how many degees of turn you have to move the adjuster - that could be say just over a quarter turn - however degrees is what it takes to close/open by .3 ( .5 - .2 = .3)
put the feeler guage back in your pocket and adjust all accordingly
technically if the thread on the adjuster is 1mm pitch then you would turn back .3 of a turn from tight, (120 degrees) if it is 1.25mm pitch you'd turn back .42 of a turn (151 degrees )
back in the day there was tappet adjusting tool made expressly for that, a socket bar with a screwdriver access through the centre of the lug and a protractor etched on a plate sitting against the register the socket clipped against, made it very easy to accurately reset tappets on even the worst worn rocker gear
adjusting to 25 will not harm the engine but may reduce what power it has

Interesting, I honestly believed otherwise from experience. Good luck with solving the noise.

update 8valve engine set tappets to .275 sound pretty good
