Tapping noise from the engine of a Cupra?!

[andy_lang]

Hi all,

I was wondering if you could help. Ive recently bought a 2001 Leon Cupra, took it in for its Cam belt and prior to this it was running smoothly, no noise at all be it hot or cold.

Went to collect it and has a HORRIBLE tapping noise!! They said it could of been because the previous owners put on a cheap-o oil filter and the tappets didnt have enough pressure once they had fiddled with everything fitting the new belt. Its only on idling, as when revs build it goes away...............
Theyve put on a proper oil filter and its still the same, so im going to go collect it!

Is this a common problem, can anyone suggest a solution?

Many thanks,

Andy

Probably the charcoal filter. They all seem to tick, quite normal.

If it didn't do it before they replaced the cambelt then surely they have cocked something up?

 

[andy_lang]

Sorry, whats the charcoal filter?
& yer, this is my worry! So I may just take it to Seat, and if its a problem that happened while they did the belt then ill give the dealer bill to the garage!!
Hopefully its nothing that bad?!

I think the ticking almost 'tapet' type sound is normal on idle

why not just take it back to the place that did the cambelt, worst case could be a tensioner not done up properly or a roller, oe a bolt not torqued properly... all will result in a snapped belt and we all know what happens then.

the longer you leave it the less likely they are to sort it for you foc.

I think the ticking almost 'tapet' type sound is normal on idle

op described as a horrible noise that wasnt there before the cambelt change though, charcoal filter isnt a horrible noise.

The carbon canister will tick when the engines not running to, if you undo the fuel cap and release the pressure this ticking will stop.


I'd get the garage to sort it, like James says if its a tensioner it could cause real trouble.

 

[andy_lang]

Its been at that same garage all the time - they dont know why its making the noise - muppets! Ill mention the Tensioners etc. But if i take it, get another garage to sort it and it is something like that then least i can bill the original garge for their poor work!
Thanks for your help.

youll have difficulty billing the original garage for any work done by another... tell them to find out why its making the noise, and redo the belt change, cant take risks with a dodgy belt change... take it its a cosher garage?

 

[andy_lang]

But its only on idle - the noise goes away as soon as some revs are applied....................

 

[james walker]

id go for tensioner, did they replace the tensioner and rollers when they did the cam change?

 

[andy_lang]

Yup, replaced the lot! Ok, ill see if they will redo the belt and make sure its all done properly. Shuda done it myself ehh!!

 

[james walker]

hmmmh, maybe not diy unless fully competant, i wouldnt attempt one myself.

can you describe the noise a little more? or post a video with the noise

 

[andy_lang]

Mates a mechanic, and ive done my fair share of engine re-builds, just flat out at work so didnt have the time myself! haha!

 

[andy_lang]

ps- ill record the noise and try and post it. but its a tapping sound, the mechanic there said it sounds like a drop in pressure to the hydrolic tappets - hence why the change of oil filter............... but that didnt solve it!
The day before it went it, it just did a constant 260mile run, no noise before or after, and nothing the following day.

 

[james walker]

was it just a cam change or service aswell?

 

[andy_lang]

Started off jus cam change with all the extras, then a service with new filter to try and solve the noise

 

[james walker]

so it made the noise before the service?

must be cam related then, or they disturbed something along the way

did they do waterpump aswell?

try post that noise matey, make it easier to diagnose.

Did they change the Oil if so? Which spec? Maybe too thin?
