More than just sweat. Little damp. Tried to torque bolt by hand but seemed a little tight. Par for the course (just check dip stick here and now etc), or fix?

 

What gasket? These cars have loads of them...

 

Head gasket

 

Following Daim's ask, I am assuming down the sides onto the exhaust manifold???.

Sadly, my mind reading machine is fresh out of batteries.

The V12 has a "tappet block" on the top of the cylinder head, and there is NO gasket between it and the head, just a chemical seal, and they do weep and leak from there on a regular basis.

HUGE job to fix.

"Greg in France" did his with an external fix that seems to be holding up quite well.

If that is not the area of concern, please fill us all in, so we can assist you with a fix.

The V12 is not known for oil leakage from the head gaskets, although some leakage appears to be from that area.

The section of the timing cover where it mates with each head can weep, but again, not common at all. Mostly an issue if the timing cover has been removed without removing the 2 heads.
