4 days ago i started to hear this noise u will hear in the video, could it be timing chain or is it more internal? what could this be?

Sounds like it is coming from the bottom end.

 

what "could" it be?

 

Are you having any issues at all? Or just this sound?

 

My WRX sounded just like that when it had damaged rod bearings. Does it seem to be coming from the top or the bottom of the engine?

 

i would say bottom of the engine the side where the timing chain is

 

That's where I thought my knocking noise was coming from before (now the engine is seized apparently ).

I can't really hear much in the vid, though.

 

Kiss keep it simple stupid. Check the timing chain tensioner first. Then check compression on all cylinders. It could be as bad as a bearing and or lifters going bad. It does not sound like a spun bearing yet. Oh and above all, Change oil try a thicker oil 10 30. Or 5 40. You could try Lucas, but I tend to stay away from that stuff. Snake oil. When they put a mechanic in a bottle ill try it. How many miles and what year. Obviously a 3 litre.

 

2000 with 10,9000+ on it, ill prob do a oil change, hopefully it fixes this problem

 

Are you running synthetic or Dino oil?. Change oil first then check for other stuff. You state it's a 2000 with 10,900 mls. Regardless of milage years of service weather driven or not add to wear and tear to all parts, mechanical and otherwise.

 

i just changed the oil in it, put in some royal purple 5-30 sounds not as bad now... ill give it some time and i think i sound should prob go away, i allways used mobel1 synthetic 5-30

 

That does not sound like a healthy engine.

 

it sure doesnt, but after a oil change it pulls harder then it ever has.
i still got the noise, ill take it to a shop so they can check it out and see what it could be.

 

I was listening further, sound like lifters. Should also check oil pump.

 

did you ever figure this out?
