What Do You All Think

Right this is a few posts off a couple of sites im on i will add them together and let you see if you can help

-------------

Right on idle the car is making a "clanking,ratting" sound - BUT it doesnt seem like its from the engine it seems to be around the gearbox area.

Could this be the propshaft?

Seems to only do it on idle aswell or when going very very slow and it goes away after a couple of miles.

What could it be?

Took it round to my mates last night and it wouldnt do it at all. No noise at all

Started doing it on the way to work so i have made a small video of it and you can hear it. But it went away after about 20seconds

Its wierd putting the clutch in or out makes NO difference or havnig in gear makes no difference.

Just out of curiosity - If it was the big ends would they rattle occasionally or ALL the time on idle

The noise goes away when the revs are applied then when the revs drop back down its usually gone lol

Very mysterious

Manged to get a video uploaded of it at work :-0

YouTube - Impreza knock - Not sure whats knocking as its only on idle OCCASIONALLY

Bearing in mind it goes away when rev'd just a little and this only happens occasionally

And ONLY on idle - it doesnt sound like its coming from the engine

Engine is running sweet and pulls like a train still

Doesnt knock at revs at all

Thanks for your time in advance people

Also i was at the garage last night and nothing could be found as the car wasnt making any funky noises only does it occasionally

Don't know what model of car you have, but could be your exhaust cover plates happened on my old sport. Welds and joint corrode and start to rattle, use to dissappear once the car heated up.

No real point in replacing them as you don't need them in the UK. I found the one that was rattling and cut it off.

well been speaking to a speacialist in Forres who seems to think its not the bottom end as he said it would knock all the time not just occasionally

He also mentioned about a tensioner on the front on the engine if its leaked oil it will make a knocking sound occasionally which can simulate bottom end.

I need to get the car checked over. so hopefully getting a Subaru dude to look at the car tonight
