Hi all
Before I rush into this could anyone advise where the oil leak may be from on the attached pic?
It looks almost like it could be from the head gasket but I can't see it being that. There's a stud behind the distributor which the oil is possibly running down.
Doesn't seem to be the cam cover or timing cover.
It's a 1968 4.2 series 1.5

Have got copper washers on those studs?

you are right chaps. There are no copper washers fitted to these underside studs.
Thanks

sadly thats normal. I vaguely recall that the stud goes through the head and sits in a small well of oil so eventually the oil works its way down the thread. Its hard to clean out in situ but I tend to use some stud stealant when I fit them.
To be fair mine still leaks so I just keep wiping it clean. A copper washer will help. Same for the other side...

Sandwich the copper washer between the head and an normal steel one.

You can also use AN-365 nuts to prevent oil from sneaking past the threads. These nuts have a fiber insert that is more resistant to heat than those with the nylon insert. They're available from any aircraft supplier and cost about the same as the hardware-store stuff.

SELOC brand washers should also do the trick.
