Question about 2000 Volvo S40
Do you think it needs new hydraulic tappets or it is the Variable valve timing control valve playing up. At idle it sounds worse than a diesel. Noise goes with load.

SOURCE: tappet noise
Sounds like worn lifter/cam lobe,quite normal when engine gets a few mles on it.Lifter is finding it hard to fill the extra clearance created by wear.What sort of oil are you using and is it clean?Wear in an engine will lower your overall oil pressure as well,not generaly enough to worry about but it does contribute to the problem.At idle or when cold is generaly when this happens?

sounds like c/v axles (front drive shafts) they will make a clicking sound normally when turning sharp and accell at the same time at slow speeds / look at the axle boots and look for grease on the inside of the front wheels leaking out the axle boots
