Cold start noise...trying to work out what it is

Hi Guys

on a cold start i.e. the morning when i start my car I get this wierd "tap" or hitting noise from the front right hand side of the car...and no its not the tappets incase anyone is thinking that.

it lasts for about 5 seconds and goes away. So my assumption is that is a moving part that needs some lurication and it gets it once the engine is moving.

I can't work out where it is comming from...front right hand side what is there?? water pump/oil pump? it seems under where you check the tip transmission fluid levels and directly behind the radiator on the right hand side. (i.e opp. side to where the pullys are)

I'm pretty sure it shouldnt be making that noise..and it only does it only does it on a cold start or when u have left your car for over 4 hours which indicates some kind of fluid drain/lubrication.

kind of a wierd one.

Chris.

you sure its not the lifters? Other than that something internals wrong with your auto, or something wrong internally!

Well your ISC can make a bit of a noise when starting up!

Water and oil pump is on the pulley ends so it cant be that!

Coudl be your oil pump and something griding in your auto! Put a screw driver onto say the auto or where you think the noise is coming from then your ear to the handle side you usually can sorch down where the noise is coming from.

yeah it hard cos by the time I get to the front of the cra th noise is gone...

I had another look and basically the auto is the only thing around that area.

I will keep investigating...might take it to my auto guys...due for a service soon anyway..

apart from that I have no idea.

get someone to start it up for you. there is only one thing in that area and its your auto. If its a more choofing type noise like a warped rotor, then i can safely say its to do with your torque convertor.

Around that area of engine usually means money!

Check your uni joint out and see if its damaged could be that.

if it was those things then i would expect it to be more constant...in fact this noise has only come since the weather has been colder.

Its like a plastic bit rotating an hitting something...then 5secs its gone...something to do with oik/water I reckon...not sure what.

horn hitting the radiator fan?

hmm dunno...why would it go away after a bit? I will have a look though cos the fan is what I first suspected as that what it sounds like.

ah huh try your AC pump. If they are not working properly they sort of make a noise as you decribed.

hmm yeah thats. I was thinking the AC or PS pumps as I've replaced my belts and checked my pullys.
