Hi everyone , sorry for the month long wait on my reply lol

Turns out it was the timing belt tensioner , the belt was really loose and was slapping around the timing case

Lol I was right. That's good news for you. I found out the hard why, after trying other things first and no one new here on the forum. But the good thing of been on the forum is you learn things and someone else will benefit from it.

If you are concerned about the condition of your bearings you could always get a used oil analysis done, it can be difficult do get an idea from a single sample but I do have some 3SGTE trend data.

Is there a way to tell if it's a big end bearing rattle before I pull off the sump ?

Bottom end usually presents itself at around 3-4000, never seen it below that.

Sounds like my N/a, and like the shims need to be redone.

Hard to say from the video whether this is related, but at certain revs which create a resonant coupling, the edge of the heat shield over the exhaust manifold can start flapping quite vigourously and make quite a strange noise.

Easy to check either way.

Unless a rod bearing is completely ferked, most of the time, when the oil is thick (read cold) it will be quiet. Its only once teh oil thins out that the noise will present itself.

I recently had a 3SGTE at my place with what turned out to be a seized oil relief valve - it managed to basically spin a fresh set of bearings in under 2000kms. No noise until warm, and only audible at between 2-2.5k RPM.

It's fine on start up , no noises at all.
When I get home I'll check the exhaust system

Does it make any rattle on start up?
Before going any further engine wise, check complete exhaust system including mufflers & cats for any loose components.
I have had a lot of cats & muffler internals cause simular sounds.

Not sure if there is. I wasn't sure to begin with. If it is, it will get worse rather quickly the more it runs.
