Hi,

I've got a 2001 Mazda 323f 1.6 Petrol (new shape) (110, 000 miles). When I start it up from cold I get a loud clunk. It makes the noise sometimes as soon as it starts up or sometimes up to 2 minutes after its started, while I'm driving. I cant find anything loose and its fine all day long! Its very perplexing.

Any ideas?

Thanks

David

 

a clunk of any kind is normally not good, and especially when effected by temperature, it's probably nothing you'd be able to "look" for yourself, have a MAzda dealership take a look at it

 

is your car auto or manual, does it studder, do the Rpms fall below 1000? Does your car (the body) shake while driving?

 

Its manual and it drives very well with no other issues or problems, engine nice and smooth starts great - apart from the clunk!

Thanks
