whining noise on idle

Hey Its Becks partner,
If you would pm becks a landline phone number i can call you on tonight i could probably talk you through how to locate the fault and how to perform tests without vagcom that might help identify what is causing your problems.
The tests aren't too hard to do. only concern i have is if the whinning noise isn't to do with the pump it could be in idler pully on the timing side of things if its there constantly when going faster and slowing down as this kind of noise could be a bearing worn causing it.
sometime you have to do mechanical tests as some computer programs just done have the capability to do the type of test that cars require.
cheers

If it is to do with the tensioner side of things pop the bonnet of the car get someone to gently rev the engine and listen to any noises coming from the timing covers. If the sai pump is failing jack the car up lie under it head first and remove the bottom cover, check for splits in the casing of the pump and you will probably see the seal sticking out of it, pock it back in and use very thin bolts to re join the casing as i had to do that to Becks car.
whoosing noise could be a split pipe at the turbo if the noise is more prominent inside the car, could be a very very small split in the pipe and when you accelerate the pressure build up to a pressure that opens the pipe and releases the pressure causing a lack in power and reduced performance, check the dv to see if the casing of that is cracked causing the same fault.
check all vacum pipes and boost pipes for security maybe one has just come loose, also check pipes at the N75 valve for splits, loose etc.
Best thing to do is get someone to rev it whilst you are looking in the engine bay that way it will lift the boost pressure and you should be able to find where it is coming from.

on idle the cambelt side does sound tractor like, tbh mate cant remember what it soulded like before.
i think theres a split pipe under the inlet manifold, the t-piece that holds the pcv valve has oil around it and it looks fresh to me, just hard to see under there.
it feels soft the pipe that is, its the pipe that comes from the oil filter housing, the t piece that joins to that.
ill check the t.i.p near the turbo end to see if thats split anywhere, would a split vac pipe near the pcv valve cause the whoosing?
cheers for the continuing help mate.

Hey,
right. cambelt side shouldn't have any noises to be honest should be smooth running. If it is noisey from this side honestly i wouldn't drive it and get it checked out asap as if it is this and the pulley or tensioner collapses then it can cause major engine damage.
if the pipe is leaking i would change the pipe and "t" piece and that may sort out the whoosh noise.
Shame you don't live near me and i could have looked at it and also fixed it for you.

yeah, quite far apart mate....tbh im ok with fixing most things as i do most mods myself, but this one had me stumped.
now i went out earlier, the whine was louder on high idle again, when it settled then the whine went away on idle, then its there again when i start driving.
hmmh??

check the sai pump as it is at that side of the engine too. but remember the sai pump is electric and will either be on or off take of the power steering belt out of curiosity and if the noise goes away its something run off of that and not to do with the timing side and if it is still there then its probably inside the timing cover and be serious.

was thinking of electrically disconnecting the pump, then starting engine see if it goes away then.
other than disconnecting the power under the pump is there any other way of disconning it.. i.e a fuse?

not sure if there is a fuse for it, though tbh i really don't think there is but i could be wrong.
you could try disconnecting it but it will bring on the engine management light. so you would need vagcom to reset it.
if you drive the car with it disconnected i think you will experience power loss so i don't advise driving it far or hard.
if the noise is still there i would look at taking the power steering belt (aux belt) off and try that then all else fails timing belt side of things.
if you are happy to do this test it may help, if you have a a long screwdriver or thin solid typre metal pole put one end against the pump and one against you ear and the noise will resonate along the pipe and you can locate it that way even for pulley noises though only put the pipe against the housing the pulley is on, you do get a special tool for this its a type of stethoscope.

i have a stethoscope mate, ive had this on the tensioner etc, would the noise transmit as a whining through the stethoscope?
i have vagcom aswell mate so resetting eml is fine.
would the sai disconnected really transmit power loss? loads remove it completely and blank it off.
thanks for the suggestions
also never removed pas belt... how is this done? cheers

i think it would as its feeding more air into the intake system though if this can be removed then i will be removing becks as they are a pain in the backside as they are noisey when the bearings go. this i will need to look into.
The noise would transmit as a droaning noise, easiest way is to put it against a pulley you know is fine then against one you think is bad and there will be a significant difference in noise and noise level.
it must be something with a bearing in it causing the noise. Using the stethoscope is the way i would be listening for the noise tbh as it is one of the easiest ways to locate a noise like that.

ill have a go tomorrow then mate..
as for the pas belt, how when and where on that one mate, never really done belts

Ok.
Pas belt. looking at the engine there is a belt that runs the pas and the altanator etc, follow the belt round until you find the automatic tensioner, once you have found it look at the side of the pulley and you will either see a hex built on it (normally a 13, or 15mm) or a square hole on the tensioner, depending what one it is use the correct tool and it basically doesn't take much pressure to move the tensioner once you have it moved hold the tensioner in place and remove the belt with your other hand and take it right off then let the tensioner go.
Afetr you have done that you can then start your engine though don't have it running for too long as the belt runs the altanator and it won't be charging the battery.
