Might be stuck hydraulic valve lifters.
What grade of oil is in the car and when did you last change it?
Some members swear by Wynns hydraulic valve lifter treatment.
Might be wise to remove the timing belt cover and check that the timing belt is still correctly aligned.
-
Oil is GM 10-40, always changed in 5000 km intervals.
But engine has done around 1000km after head gasket change with new belt and tensioners.
-
That's definitely not right.
Oil pick up tube blockage?
-
So, remove sump, clean strainer if there are debris, fresh oil and filter and fingers crossed?
Noise just sudenly appeared, out of the blue

Which suggests a blockage.

Thanks...Will update this

This was what happened to my engine when the strainer got blocked : https://www.omegaowners.com/forum/index.php?topic=122287.0
Some mucky pictures for you to compare. If there are chips of white metal in the sump when you drop it, then you're probably going to have to do a full bottom end rebuild.

Well, that wasn't very nice to see at 4 am before going to work :-\ Will drop the sump at the evening and hope for the best. Thanks

I'm in Laa so probably 9-10 hours behind...
At least I didn't ruin your breakfast >:D

did the noise just suddenly happen whilst driving or did it occur after a few repeated short starts such as moving it around the yard etc . a stiff lifter can sometimes make a noise after this and once the engine warms up the lifter will usually start to adjust itself as normal.
oil starvation from the pick up pipe is a common issue but can be checked with a pressure guage anyway .
-
I got the oil pan off...there is no glitter or any residue. I've found two small metal pieces in the sump and one in pick up strainer. Pics follow

O ring from a cam cover gasket change dropped in :-\
spring clip :-\ retainer for a little end :-\
has the knock gone ?
was the pock up blocked ?
-
Strainer wasn't blocked at all, what concerns me is those three metal parts...they look like part of the block or rod
-
Wrist pin retainer and I suspect a chunk of piston, that circlip is not working its way past the piston without damage and the little end pin will be rubbing on the bore scoring it. Strip down time.

Strip down time.
bore scopes are cheap

Although this doesn’t change the outcome of a strip down, if memory serves me correctly, the V6 piston Gudgeon Pin clip can drop out and get past the piston with no damage as the piston doesn’t have a full skirt. It is cut away for the pin and clip on the sides and as the top ring, middle ring and oil ring are above the gudgeon pin, it has nothing to stop it falling downwards. The full skirt IS on the con rod stroke sides. As said above though, the un-restrained pin will do some damage. I may be wrong and stand to be corrected without being offended. :)
As I say, it changes nothing as the clip needs replacing to stop the pin moving, so a strip down/rebuild is inevitable.
Not what you need to hear I know. :(

Well...200 km later, the noise is gone ??? It sounded like sewing machine for 150 km and then slowly disappered...Strange or just preparing for something worse
