Engine rattle/tapping on startup

Without too much diagnosis, it sounds like your oil is frothing a bit when cold.
However, cloudiness could also mean a bit of coolant getting in there but don't panic about that without further investigation.
It may have a detergent characteristic too it.
Frothing can be caused by overfilling the sump as well.
I recommend Mineral oil and a bit less than 4 litres when filling.
(Motul 3100 gold is my prefered - not pure mineral but sem synthetic)

I have tried synthetics and I find that mineral oil runs quieter than synthetics.

coolant getting in... thats what i thought! thought a gasket was about to shit itself.
i had a service 500ks ago... hhhmmmmm.
next time someones having a garage sesh(not with the bong), im in.
