When should the camshaft and rocker arms be checked?
If the engine has a persistent top-end ticking noise, remove the rocker cover and inspect the cam lobes and the roller on each rocker arm. Look for pitting, scoring, a worn-down lobe or a roller that does not turn freely. A noisy engine does not automatically need a new camshaft: the chain tensioner and other valve train parts can also make noise.
Check what caused the wear
A new camshaft will not fix an oil supply problem. If the old lobes or rocker rollers are badly marked, ask the mechanic to check the oil level and supply, rocker shafts and their oil passages before fitting new parts. Also check the cam bearing surfaces and remove any metal debris. On an R53, a normal OBD scan cannot give you a measured oil pressure reading from the standard warning switch. Suspected low pressure needs to be checked with a suitable gauge. This extra check matters because a blocked passage or low oil pressure could damage the replacement parts too.
If the cam lobes are sound and you only have a noisy or damaged rocker, have the complete valve train inspected before deciding which parts to replace. The rocker shafts are not included in this kit.
