Any Ideas People? Rattle driving me nuts...

[-UNKNOWN-]

Well, changed my timing chain today in hope of fixing the death rattle I had. No luck, new chain, tensioner and new water pump. Also changed the H.B not long ago.

Any ideas people! Im going bald from this!

[dufus]

Can you describe the rattle to make it easier to diagnose where the rattle is coming from.

[-UNKNOWN-]

Its like a ticking kinda rattle, its loud. I can hear it with the hood shut standing like 10 metres away. Lifters maybe???

[dufus]

I can hear a ticking noise when my car is running from a fair distance away with the bonnet shut. In my car i believe that it is the belt tensioner. So it might be worth checking that out.

[-UNKNOWN-]

Mmkay, how do you tell if its that though?

[stocky]

think i got the same noise. was told its lifters. some people have suggested running a thicker oil, but i havent tried yet

[-UNKNOWN-]

If it is the lifters is it hard to replace them, I need to stop this rattle!

[Grennan]

If its the lifters just try a thicker oil next time you do an oil change. Does it seem to happen when the cars been running for a while? Or when its still a bit cold?

[dufus]

Mmkay, how do you tell if its that though?

When my car was at the mechanics last time he commented that my tensioner needed replacing and showed me that when reving at about 2000 revs, you can see the tensioner bouncing up and down slightly in tune with the tapping noise. I still havent got round to replacing it though.

[Not_An_Abba_Fan]

Put your finger on the tensioner while the car is running, not the spinning bits though, cos it would probably hurt. You will feel it if it is making the noise.

[88GreenVN]

Probably not it but the oil pumps can make a racket too.

and the balance shaft bearings and cogs wear out normally the rear balance shaft bearing from what I here

[Sgt Santa Cruz]

Yeah dude check the balance shaft i went through the same process u did i eventually just took it out and replaced the timing gear with double row. idle wasnt that bad and noise was gone. i hated that noise makes everyone look at ya lol but its a very common thing on those motors

[Ra1d]

i had a craphouse rattling noise comin from under the bonnet too. was particularly bad when pulled up at the lights (ie. in gear idling). replaced the serpentine belt and that quitened it down most of the noise. my old was pretty perished, might be worth checkin yours.

been told idler pulley can make a fair a bit of noise if worn as well

[-UNKNOWN-]

Well, its either go hunting to fix the rattle or buy an Eco Super6 now!

[lasco]

have u checked ur harmonic balancer?
or else, as everyone else has said, ur lifters.

[-UNKNOWN-]

Yea replaced the H.B. not long ago...

[TheForgotten]

lifters are pretty common, so are injectors. to replace lifters remove heads and manifold, pull out out pushrods, unbolt retainers and lifters come out. my alternator ticks aswell

[-UNKNOWN-]

So many things that tick and knock...!

[cxcxcxvcvcvc]

my vs calais has just started to make a rattleing sound from somewhere like the timing chains about to die or maybe its just one of the pulleys? it only does it when under load

[Not_An_Abba_Fan]

Two possibilities, the harmonic balancer or the belt tensioner.
