B14 average valve adjusting mileage ?

[gl340]

Wonder what is by experience average interval for adjusting valve clearance on B14 engine. Volvo book says 20.000km which to me seems rather small.
Is any difference in reality if solely LPG is fuel, this engine looks pretty robust with valve seats.
Is anything specific to make attention when adjusting valves ?
Have greeen manual copy.

Normal enough for screw adjustment rockers on a push-rod OHV engine.

Special tool = 2 hands. Without = 3 hands!

Don't over-tighten rocker cover. If it has been in the past, then hammer out the dents.

This is normal.
Don't forget that it was written in the time when cars were serviced every 2500 km.

Ok, thanks to both. I hoped it is more toward 200.000km like on red block

Advice ; adjust the exhaust valves at 0.25 mm instead 0,20 mm (cold) for running LPG

ok.
