Tapping in engine bay?

[lewis1984]

Hey guys, I was parking my car tonight and heard a tapping noise, on closer inspection i discovered that it was coming from the back, somewhere behind the engine.
Its a 20vt with 80,000 on and has had a water pump change at 60,000. The noise is very quiet at the moment, but as you can imagine im a little worried that it might become worse.
Has anyone had, or heard of anything like this before?
Thanks.

sure your not thinking of your carbon canister?

The Carbon Filter ticks on these engines. It's on the offside front next to the wing.

 

[lewis1984]

No sadly its not. I can hear it echo slighty in car but I had to really stick my head in the back of the engine bay to hear it clearly.
Im gonna give it an oil change and see if that helps.

what happens if you adjust the interior fan speed?
I cant think of anything else thats 'behind' the engine that could produce a clicking..

 

[lewis1984]

its with the fan off, its sounding more like a knock today rather than a click, and its a little louder.
Im just hoping its not the turbo. but there isnt any power loss so. I dunno pretty stumped.
Gonna give it a service tomorrow and try to get a hold of my mates vagcom. Fingers crossed its just something silly.

What DV are you useing ??? If it's a split-R they can click

i think i may know the sound your thinking of, like a really quiet noise that sounds like some really tiny person is knocking on your bulkhead? i notice mine does it when i get to the end of a journey and listen carefully. I thought that was just a normal car noise..?? please let me know if you find that it isnt. could it be cambelt on its way out?

 

[lewis1984]

Thats totally it. damn iv been trying to describe that noise for ages now. Good one. Im going to investigate tomorrow, do a bit of a service. I'll let you know whether or not i find anything.
Probably just paranoid.
little tiny person, lol

 

[lewis1984]

Oh im not using a split r, Iv just got an S3 recirculator. Still I'll give it a check, Thanks.

 

[lewis1984]

Dealt with, i just gave everything a good tighten. Spark plugs, that thing on top of the coils and my dynatwist. Fingers crossed thats it all done.

 

[olliep]

ooer, bit odd. well done mate

could be heat settling from the exhaust or turbo or hot parts that settle as they get cold or heat up maybe like in your house like the pipes, just a thought.

could be the exhaust heat sheald had a knocking noise on my leon cupra taken to garage and they fixed it no noise!!

wish it wa something simple like that. its too regular and very fast.

 

[lewis1984]

If your not using bolt down coils, it could be them rattling about. I think thats what it was on mine. And because they had been moving about, my spark plugs had loosend. Im gonna have to some extra covers for them Like the one over the left plug which the black thing sits on.
(Very technical)

think its a vaccuum resevoir. And i believe awesome sell them but at quite a price for a few clips. DIY is a thought me thinks. (or blu tac)

cambelt tensioner can click when its struggling. are you hearing the coolant pump after switch off? if thats failed i wonder if it would tick more as it cools
