Ticking from the engine

I just bought a 86 240GL with 160,000 miles on it. The motor is ticking and im pretty sure its the valves, My question is, is this a common problem with volvos? or do they all tend to do that but theyre still fine. also if it is the valves is it a simple readjustment or worse?

Is it a ticking or more of a slapping sound? Does it only happen during warmup?

Yes, at 160,000 miles you could be looking at a valvetrain reshim.
It could also be your fuel injectors ticking, which is another very common noise, but not really anything but a cosmetic problem.

Guess,

On your Volvo engine, the gaps between your camshaft lobes and the valve caps are adjusted by shims ( round shims, little bit bigger than a quarter). These shims come in different thickness. After so many years from engine operating, things tense to wear out. Shims at time need to be adjusted by changing out different thickness size shims. Doing so require special tools. It can get quite technical. Should you require a valve lash adjustment, I advise you to let a Volvo specialist do it for you. The labor doing so is average about an hour of work plus shims and valve cover gasket.
