Engine noise
 
Can anyone help i currently have a 2006 hawkeye Sti my engine has developed a strange knocking noise sounds like metal to metal!! Been into garage they wasn't 100% sure what it could be!! I'm hoping someone might have had the same problem and can help me out
please take a look at new video revving up and the noise speeds up http://youtu.be/ZB7foAK9sLU

hmmm hopefully not the dreaded engine knock. does sound louder near the turbo tho, maybe the bearings have gone in your turbo. post another video whilst revving the engine as engine knock has a specific sound but its easier to hear when revving the engine. its more like a low, thudding metallic noise that becomes more prominet as you rev.

good luck.

I will do another video tomorrow when the engine gets to temperature the noise stops! Because when I took it to the garage he couldn't hear anything!! The Garage is about 7 mile from my house. The garage said they think it's internal but I want a second opinion on it!! http://youtu.be/ZB7foAK9sLU

Could be piston slap from cold,worn cambelt tensioner or front pulley loose.
Onset of big end failure can be heard around 2500rpm coming off the throttle.

Hope it's nothing serious though.

Hi

Had all belts off garage have checked all pulleys I will put a other vid on tomorrow whilst revving it slightly see if that can help cheers for your replies appreciate it

Could it be your clutch fork? On mine, where the clutch fork pokes out of the engine and connects with the slave cylinder, it makes a metallic tapping noise for some reason. I've had my car for 4 years now and it's always made this noise as far as I can remember

Hi

Does anyone think it sounds like bottom end!! Few people said it sounds like it!! Need to take it into scooby clinic but wouldn't mind if anyone else as an opinion on it

Hard to hear it but don't sound like the bottom end, id get the cam belt tensioners looked at though don't sound too good.
forget that just noticed you have already done that oops lol

yabbadoo4 14 March 2016 07:47 PM

the video i posted is engine knock. around 46 seconds in when he revvs it. if it sounds like that get your wallet out.

I agree that it sounds top end related.

So, hopefully, a big fat "phew", on that front...

yabbadoo4 14 March 2016 08:02 PM

the new video you posted doesnt sound like knock at all. could be the tensioner or bearings. did sound louder near your turbo in the first video tho.
