Any suggestions guys?

 

Sorry to say but it sounds like it to me, Does it rattle a little bit when started and turned off too?

 

no, no rattles or anything like that.

 

i dont hear engine knock at all? thats not engine knock bud, this is engine knock, @ 46 seconds

 

Just taken it for a half hour drive and the sound is still there?? No louder and no quieter?? Could it be the start of something major?

 

Just take it back bud, wouldn't risk it. Either way why should you put up with a knocking noise, if you have paid good money for it.

 

Fair point, just such a nice car in all other respects

 

I've had a few slappers in my time!!! Deffo sounds like piston slap although its quite bad for a low mileage non forged engine.

 

Does it happen through out the range or just say, 2500rpm for a couple of hundred revs above then dies off?
When I got it, it only came on at those revs, eventually it gets worse but the onset is quite a narrow band of revs where it happens, mine was certainly louder though.

 

Got piston slap on my 1998 impreza turbo and sounds just like the video.

 

Starts from idle then can't really hear it after 2500 Ron. Still does it when warm

 

apologies bud i listened with ear phones and i can hear it now

 

What are your thoughts yabbadoo?

 

had a listen on pc with good speakers. that is piston slap. it is quite bad though and confirmed by the fact that it does not go when its warm.

 

well its def knocking, so you take it back. i know what its like when you like a car but its got a knocking engine which will cost thousands to rebuild.

 

Looks like that's what I'll have to do. The dealer is over 4 hrs away so hopefully they will be understanding and refund me and send a transporter to collect the car.

 

Piston slap not rod knock . Need a video of the car hot to see what it's really like

A thicker oil may be required

 

I'd give them a ring see what they say. You could pay to get it transported to them, depends how you paid for it. If with cash then best drive it back down to them, and make sure they have money to give you back. What date did you buy it?
