SR20DET: Rod Knock or Timing Chain Guide noise?

[Dee]

Ok so my completely stock sr20det started make a noise which to me sounds like a failing rod bearing just not as violent and it's strange to me because I change and check the oil religiously and I occasionally sprint drive it through the local pass up here but that's it.

Now down to the conditions. The noise occurs around 2,500-3,500 rpm on light or hard throttle and it disappears until around 6,000 rpm then you can faintly hear it again. I am unable to get a video at the moment but after looking at some videos on youtube this guy has the exact problem as me down to the same rpm range the noise occurs.


Tomorrow after work im gonna pull the valve cover and have a look around...but Rod knock or guides?

Just want some friendly opinions is all.

Thanks Zilvians
