Why in the world would you replace the camshaft, which by the way there are
2 of? My engine has gone 325 000 km / 206000 miles without the internals
being touched.

You don't replace the camshafts. You may well want to replace the
cambelt, but it will only have one if it's a V6. You don't say if it is.

There are lots of parts that will need replacing at some point, some
moving some not.

Brake pads
Brake disks

Spark plugs
DI cartridge

Oil
Brake fluid
PS fluid
Auto tranny fluid

Oil filter
Fuel filter
Air filter

That's for starters.

Your friend probably asked you to find when the camshaft drive belt (aka
timing belt) has last been replaced. The camshaft(s) do not normally
require replacement *ever*. His advice would only apply if this is a V6
engine, which has a timing belt, not the inline 4 which has a timing chain.
Timing belts are best replaced per the recommended interval (I forget, maybe
30k miles). If you do not have a record of when it was last changed, do it
now. When a belt breaks it is an expensive head replacement for the bent
valves that will occur.

Chains, OTOH, do not have replacement intervals. They usually last greater
than 100k miles if the oil has been changed regularly and the engine has not
been overheated. They usually get a bit noisey and can be identified by
listening to the engine at idle.

Thanks everyone

I had the same thoughts about the camshaft as you seem to have but it is
good to have this confirmed.
It is a inline 4 so it has a timing chain so I won't worry about replacing
this.

Thanks for all the help.
