fabron Posted September 24, 2021 Report Share Posted September 24, 2021 My 4 has developed a constant ticking from the fan dynamo area, bit like a busy sewing machine as my wife says. Tempo increases from idle but does not affect performance. Very tiresome, ideas? Quote Link to post Share on other sites
RobH Posted September 24, 2021 Report Share Posted September 24, 2021 If the fan belt is OK then dynamo bearing or water pump? On mine a similar but intermittent noise was a cracked front dynamo bracket. Quote Link to post Share on other sites
rcreweread Posted September 24, 2021 Report Share Posted September 24, 2021 (edited) Hi - welcome to the forum. Do you have a name we can use? Try taking the fan belt off and running the engine for a short time - if the noise has disappeared then your problem is likely to be either the fan belt itself ( unlikely) or the water pump or dynamo bearings. If you can find a pair of tights, fit them in turn around the bottom pulley and the water pump and dynamo and you should find the noise. if the noise persists when the fan belt is removed, then my bet would be the timing chain tensioner. Good luck and let us know how you get on. Cheers Rich Edited September 24, 2021 by rcreweread poor grammar Quote Link to post Share on other sites

You might try narrowing the source down, by listening with a screwdriver directly on 'The Ear' and touching various parts of teh area you suspect. BE VERY CAREFUL NEAR ROTATING PARTS1 John.
