Anyone any ideas?  Bought a 2002 2.2 CD Auto Saloon back in January. Noticed a top end ticking and oil was black as coal.

Have done a couple of short oil changes and added Wynns Lifter Treatment which has quietened the top end ticking and oil is now nice and clear.

However now I notice that when the engine is up to running temperature I can hear a similar ticking but it's coming from lower down. Can be heard down by front wheels on both sides of the car. It's not there on a cold start, idle is very quiet and smooth, so thinking it's not the exhaust fanimold.  When revs are increased even just very slightly the ticking disappears. Do you think more short oil changes will help?

Mine does that. Think all the 2.2s do to a certain extent.

Thanks, I've read that the Z22XE can be a little noisy, but thought that implied either noisy lifters or leaky exhaust manifold. I don't think this noise I'm hearing is either of these and am worried it could be something more serious.

Does it sound like this? Wait till the car goes over the camera properly. That clicking sound? Normal. That's my car too

Thanks again tgm, great that you had that video!  You've put my mind at ease as mine isn't as loud as that, but then again I've never heard mine while someone drove over my head!    I'll keep doing short oil changes to see if it will quieten down.
