Wierd noise
Im having a bit of bad luck with the Scooby at the moment and it seems more is on the horison either way im not giving up lol
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?

Sounds like Clutch Release bearing IMHO and will more than make a noise when warm etc...
Let us know how you get on matey?
If you can get a large good screw driver and listen at the end of it (Like a glass to a wall) to see if you can pin point the noise and then it wont be to hard to work out!

Ok mate
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
Any info would be great or ideas.

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

Does anyone have any ideas?
Whats pissing me off more is im off on holiday next week and need the car to do a 300mile trip
Im thinking of filling the car with petrol tonight and going on an epic adventure of mystic discovery to see if the car will get any worse.
Unless anyone has any other checks i should do.
When i finish work im going to - Check the heatsheilds, check under the car for anything broken/loose etc etc

I can't hear anything on that video!
Get the car jacked up and get under there and look for anything loose!
Could it be exhaust rattle sometimes when bringing on load ?

I dont know if this is coincidence but my crank pulley looks buckled on idle - If it is i assume it is the feared bottom end thats funked
we noticed it before that it wasnt spinning proper didnt look bad at all but now it seems worse but onviously goes away when revved as it levels out

I would expect a bottom end knock to be there all the time, not just intermittently. I mean you could rev and it would disappear (or get worse) and then when you got back to idle you would hear it again.
Have you done anything with the exhaust downpipe recently? There is a bracket on the downpipe near the gearbox and if that is loose (or bent - caused by speed bumps perhaps) the exhaust can clatter occasionally. I had this when I changed downpipe a few years back

did it knock like in my video mate
Also been speaking to a specialist 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

Now heres a thing...
I had to take my down pipe last week and when I put it back on I forgot to put the bolt back in the bracket that bolts the down pipe to the gear box and all seems fine apart from the odd time it rattled sounding like the back of the engine!
Jacked the car back up and found I missed a bolt and when bolted on the noise has gone!
Have you also tried getting someone to sit in the car with the hand brake on in gear slowly bringing it on to load just enough for the clutch to engage and the car dip under load ? While someone has there head in the engine bay ?

Right had my mate round who has built a fair few EJ20s now and has said its 100% not the bottom end - We have driven the car for 45mins and its not made the rattle at all and that was from cold - Checked everything but cant find it but he said for sure its not the engine.
We are taking it to the farm to put it on the ramps at 7pm for another few checks aswell

Did you check all the heatshields as i mentioned earlier on?
My car has one that sometimes rattles when the car is ticking over and other times it doesnt. It sometimes does when pulling away in first but you dont hear it in anyother gear. Its a metalicy clanging rattle sound. I cant hear your video to compare as i am work.
