Did an oil change on sunday. Started car this morning and left running to defrost windscreen and went back inside.

When I came back out I could hear a light knocking noise coming from bottom of engine

This noise "goes away" after about 2500 rpm

Any ideas  :-/

soumds like big ends but i hope not !

Have you checked the oil level since changing it and what oil did you use?

[bighed]

I thought if it was bigend the noise would stay or get worse up the revs??  :-/

Not checked oil since no.

Will go do that now.

Oil was 10 40 castrol magnatec as got a very good deal on it

Sticky cam follower/lifter?

Does oil get round that much on tickover?

If it's big ends your know there is nothing light about them when they go they knock!  Providing you've have filled the sump enough and the car was fine before I'd say it's very doubtful it's big ends.

It could be lots of other things check you haven't loosened something and forgot to retighten it or that something hasn't loosened off due to the cold.  Engines do make odd noises at times or you are hearing a normal noise differently and once you hear it it will just seem to get worse and worse it's probably nothing at all.

Just check over everything and monitor it.

............
it or that something hasn't loosened off  ......

Sump plug?        

I have seen that done. Old oil had been dropped, and the new oil had been poured straight onto the floor ...... via the sump drain ......

big ends can knock at low revs till oil pressure builds chaps !

Its defo not big ends then as it was still there after a good 14 mile drive today.

Just been and checked oil and its bang on the maximum and still its lovely golden colour

Wouldnt the noise be coming from the top of the engine if it was this?  :-/

[bighed]

Two more quick questions also  

Can anyone suggest a decent place to get a new drivers track rod end from as prices and quality vary so much on ebay

Also when braking on ice today and abs kicked in it was very loud in shuddered the whole car and steering and didnt sound too clever.

To be honest this is the first time I have heard the abs since buying the car 12 months ago  :-/

True but sometimes you can think a noise is coming from towards the bottom of what you can see.

Take away the plenum, intake manifold etc and the top of the engine looks like its in the middle/bottom of the engine bay
