Oil leak help
Hi guys, hope everyone is enjoying the festive season!
I have been tracking down a quite major oil leak and thought I nailed it. The rocker cover nuts were loose so I thought nipping them up would solve a leak from the front / top of the engine on the exhaust side. There was sign of oil stains from the rocker cover corner so I had my hopes pinned on fixing that.
Unfortunately, it still leaks like a bastard. Today I went for a run and popped the bonnet to find oil pooling and dripping off under the boss that houses the chain tensioner spring. I am thinking it might be the cam seal or upper cam housing.
There are some really good pics of the area, as well as others at this great site for anyone contemplating a turbo conversion with access to 745 bits.

You can see one that site the donor motor had a shot cam seal and leaked like mine is doing, down the front/top exhaust side of the motor, so I am thinking mine might be fk'd also. Becuase I don't have a dizzy and just a blanking plate, I am assuming that all I will need to do is reseal the cam housing and not change any oil seal as such looking at the OEM picture

Can anyone advise on how difficult is is to change the cam seal and reseal the front housing? I would probably do it with a valve adjustment.
Cheers
Edit P.S. Oil/water look ok so I don't think its a blown oil gallery in the head gasket..
