Ratte Noise From Engine... Poss Cam Chain?

[Stevoo]

Evening all,

Just come back from an 2.5hr round trip. The gal was fully loaded. When i was say going up a slight incline or in 4th gear on a 60 limit, I kept getting was sounds like a rattle sound from engine bay. it did sound like a chain type noise.

 

My car has done 88k and a full service history with oil being changed yearly. I dont think its my cam chain as i rev car stationary and no noise. I floored it from the lights so car revved each gear hard and no noise. I just get it when engine is under load.

 

My fan belt does scream now and then as the belt and tensioner need replacing but ive been putting tulcan powder on to shut it up while ill wait till after xmas to replace it. Could this make a rattle type noise if bearing in tensioner is naff??

 

Im not driving car anymore incase its the chain.. any ideas? or prices for a new chain cam kit?

 

 

Thanks inadvance.

Mines a 2.3 petrol as well, cam chain isnt an engine out job. theirs not great access but can be done like any other fwd engine.

 

Is your rattle all the time? or only when engine is under load?

It does sound a bit like the timing chain - in my experience (not with this particular engine) timing chains do start to 'clack' under load when they are seriously worn out.

Have you checked out other possible causes, like CV (universal) joints?

I agree that the auxilliary drive belt tensioner (or something that it drives, like the alernator) could be suspect - this is where I would start, as it's relatively easy and you already have other symptoms.

Its defo from engine thats for sure you hear it more on the driver side. I have car booked in on thursday so they can take the belt side of engine apart and replace aux belts and inspect cam chain/tensioner and water pump while they are their.

Will post update on friday with the deep hole in my pocket lol.
