strange metallic chi chi chi chi rattle on acceleration

[marky-gee]

Ok ive had a look back at previous posts using the search bar and cant find any what mention what im experiencing

Right when i accelerate im getting the very very faint rattle(like a well oiled chain would sound) when i lift off the sound go's away. Now this isnt some sort of heat shield rattle or a noisy tappets sound like a biro being bashed on a table,just a very faint timed rattle under load.

the only way i can describe it is like if you were to put your tongue on your front upper teeth breath fast in and make chi chi chi sound

now ive never had a golf before and im not sure if this is just a quirk of the engine or wether something need sorting

HELP !

sounds like spark knock.   yu have to much spark on  or fueling issues

The car seems to run fine. Is there anyway of checking?

[danny_p]

put a timeing light on it

Had another wee poke about and I think it's coming from around the rear or under the iet manifold(not heatsheild) or fuel line area...any ideas?

what dannyp said, check your timing first!

Took it to the local volks centre and they say they think its the exhaust manifold gasket leaking, as one of the engine mounts are shot as the engine can be rocked my hand !

Still looking, still wondering, dam annoying sound. i say its prob pinking, but they say the 8v engines cant be timed. i have gave it the best service its prob ever had and also fitted a new exhaust system.And yet this noise still torments me.

Oh and changed all 3 engine mounts.I just find it so strange that i cant simulate this noise when stationary no matter how hard i rev it

I only ever get it under load when driving, very faint when very very light throttle and increases to max noise when you floor it (no matter what gear) and stays at that level right the way through to the red
