Engine Developed Slight Tapping Noise
I have a 2004 Facelift Celica and I noticed yesterday that when idling there is a slight tapping noise coming from the left side of the engine. I have just had the clutch replaced and I had a knocking noise from the clutch bearing which sounded similar but was fixed. I have tried listening to the engine when the clutch is down and the tapping noise continues. It is not heard when you rev it only when idling. I get some bad vibration sometimes when idling but not all the time and the car had a full service in Feb.
The new clutch is juddering so I'm taking the car back soon as my mechanic said that the clutch required 1,000 miles to break in.
Does anyone know what this might be?
