Where is this leak exactly?

Hey guys,

Recently did the water pump and thermo and noticed this. What's leaking or needs replacement? Couldn't really tell.

Thanks!

VCG maybe ?

Yeqh most likely VCG. Take a look from the top and around the cover. Also Oil filter housing can be leaking.

Appears to be the fitting for the turbo oil drain line.... The o-ring that seals the fitting to the block is known to leak with age.

Could be VCG, but that's a long trail to follow, so should be easy enough to verify if it is.

It looks like it's dripping down the oil drain though, so maybe the gasket at the turbo instead of the o-ring in the block.
