mine makes a noise until the cars making more noise so up to about 2.5-3k revs from idle

dropped it off today they took the cover off and there are some chunks missing from my cambelt so i am putting in a new cambelt and pre-tensioners and hopefully that should sove the prob

ill tell them about that pointer aswel

if your going to replace the tentioners and intend to kee pthe car i really would recommend getting some of sbd metal idler pullies! well worth getting!

Davcohen!!! Got EXACTLY the same problem as what you're having. Same sound but have it through idle and general cruising around in the car. ONLY time I don't hear it is under hard acceleration. But that's more likely to it being drowned out rather than actually not occuring. LOL. Really ticking me off.

alot of noises are a pain in the arse lol .. start with the most obvious things i think

hmm still not sure if i should get him to replace the cambelt and that.

the weird thing is at idle there is a slight noise coming from the belt, could even be normal but when u rev it even when not moving above 4k u hear the noise which sounds as if its coming from below the injector rail between cylinder 2 and 3

however some guy was feeling for vibrations and said when the noise came in he could really feel vibrations coming off near the cambelt, would it be possible for the cambelt/ pretensioners to be making noise but the noise appearing to be coming from somewhere in the middle of the engine?

i might just get it done away as a pre-caution

the pointer on the cambelt tensioner sometimes tapp against the waterpump on the small xe's when the engine is revved .. might need the pointer bending back a tiny bit .. or if you dont use the new bolt with the new tensioner it will make a noise too .. old bolts are normal ones and new one has a star drive head .. if you use old 1 on new tensioner the bolt rubs the crank pulley and makes a noise too

I have the same issue on my X16XE engine. Just replaced the cambelt and tensioned up correctly. Replaced the lifters thinking it was them "tapping" also. But to no joy. Still the noise. Suppose it could be either the tensioner uni (but that was new around 8k miles ago). So i'm guessing it could be the water pump. Or maybe it could be the tensioner and was ajust a naff one. Seems quite a few people have this issue. Will look out for answers to this. :thumbs:

he reckons it could be this, he is gonna check it out for me in two weeks time he said it could just be the pretensioners as they are plastic

i dunno have to wait and see i guess

as above, my x14xe was making this noise, turned out to be the timing belt tensioners. may as well replace the water pump while you're at it

sounds abit like a fvcked big end

if it is timing belt related you need to get is sorted now if the belt or tensioner fails you will be looking at a very big repair bill, more than likely it will scrap the engine

taking it to a mechanical friend tomz maybe he will know

i have the exact same noise. at just over 3k, if you find out what it is let me know :D

will check that out aswel, seems weird but the noise seems as if its coming from behind the glove box (obviously not the glove box or its contents)

i suppose it could be, ill have a listen out for that but it seemed to be coming from the opposie end of the engine bay

My water pump or sump rattled at high revs on my old corsa, just needed replacing

Got a Corsa Gsi C16XE,

Now it drives fine more or less but when revved to over 3k or so it gets a little rattly as if there are like a couple of ball bearing loose in the cylinder (closest to the passenger side wing) seems worse when u drive it hard in a gear then let go of the gas as the revs drop u can just near this rattly sound

someone said it could be piston slap i have no idea what this is or if this is true, any idea's?
