Engine Tapping Noise

Recommended Posts

The engine on my Mk2 RX300 (29k miles) has a pronounced tapping noise when cold. It sounds like a valve tappet or fuel injector and seems to come from the left side of the engine near the aux drive belt.

Once warmed up it is no longer audible from within the car but a sort of valve noise can be heared under the bonnet on the left side.

Has anyone else heared this or had any experience of a similar problem. The car is covered by the Lexus approved car warranty.

Thanks for your replies, I am probably worrying about nothing although I will mention the noise when the car goes in for next service.
