I can't answer the question about under load, as I cannot hear the noise at all when driving :)

Odd, as I thought I had similar issues as yourself, but mine's actually more audible under load and with revs... I'll be starting with an oil change and go from there. Will watch this thread with interest, and hope you get sorted very soon.  :y

If JamesV6CDX has an engine fault he's unsure of then none of us are safe!!!  :o

You did use the T-vents from the original engine?

What are T-vents used for and where are they in the omega  ???

Inside the cam/lifter area they channel oil away IIRC?

Hiya, do one little test for me, when the engine is running lift off the oil filler cap and tell me if it changes the level of noise.

It's there... Just fitted with without the filler neck and therefore obscured from the camera by the cable tray  :y

That doesnt sound like lifter noise. Possibly bearing noise cam belt related , there has been a few duff cam belt kits around  :-\

Here's a daft question for you......are all your spark plugs tight enough?
I've seen it before albeit not on an Omega!

That engine was from the 120k MV6 estate and did not have that sound with the old 3.2 heads so I would say it is from the 3.0 heads you have added to the engine. I know you have done the job 100's of times but when you did cam covers were all the oil ways/drains clean :-\

is it louder with the filler cap off (i.e. is the noise coming from the top end)?  difficult to tell but sound like belt related to me not valve.

Took the Cambelt kit off today.

All good. Idlers all run totally smooth.

I took the 246 rocker off. All looked good. I took the camshafts out.

It would appear some metal has broken off under the Inlet camshaft on the head.

Bugger it.

Metal has broken off? Sure it's not just a rough edge on the casting?

A picture would be handy. :y

I thought the same, and the fact there is no sign of any foreign object or filings would be consistent with a rough edge...

No explanation for the noise, though!
