I had a search but couldn't find the info i was looking for so here goes

I went for a drive tonight and when i got home my engine was making a ticking noise, while the car was still running.

it sounded like a stuffed bearing on the alternator or ac pulley, but the sound is emanating from under the engine on the passengers side.
It has had this noise for a while but it was much louder tonight then i have ever heard it before.

while i was driving there were no signs of hesitation from the engine, and no other noises that i could hear.

Could there be a crack in the exhaust manifold causing this?
It almost sounded like the tick noise was happening a little over twice every second, which given the car was idling makes sense.
The noise also increased in frequency when the engine decided it would up the rpm a little.
Also it gets more noticeable when the engine is warm.

Is there much i can check for with standard tools or is the consensus that i will have to take it to a workshop?

would you care to elaborate?

Shims, big end bearing stuffed, low oil? Any of those. In all seriousness, get a quick vid that clearly airs the noise so we can listen. Internet mechanics is serious business.

check the spark plug boots (the rubber things that go over the plugs). If they are not fitted/sitting correctly, you will hear the tick of the spark firing.

happened to me a few years back and everyone speculated that it was a dropped valve etc.

take you 30 seconds to check and fix.
