Default ZVH oil leaks driving me mad!!

Ok peeps just wondering if anyone can help me with this before i break the bitch.

I did a zvh conversion last year which doesnt run too bad apart from running rich but i cant solve these 2 bloody oil leaks so i can get it set uo.

First one is from the dizzy seal which i have changed for a genuine seal but its still leaking like fuck.

The other is either from the cam seal or the pulley bolt and ive changed the cam seal twice till somebody mentioned it could be leaking from the bolt so i locked and seal this with the blue stuff but its still leaking from somewhere which appears to be the bolt as i have bits of oil on the outside of my vernier.

Ive tried pft tape as well with no joy, could i have too much oil pressure iis the only thing i can think off but my guage reads about 89-85psi on full chat and i aint got a clue if this is too high?

I have a bailey oil seperator which is breathing to atmosphere and not to the metering unit and i aint getting no oil coming out of the pipe so aint got a clue why im getting these leaks from the head.

Am i missing something obvious as in the 11 years of owning the car i aint never had trouble with leaks before which is whats making me think is it something to do with the bottom end.

At the end of my tether with this and any advice on what im doing wrong gratefulyl received

Everyone stumped like me then, i posted my probs a bit back in the rst section and jano said i could have a bearing siezed, anyone know whre this bearing is cause i aint got a clue??????.

just read up that the maximum oil pressure on a 1.8 zetec should be 60 psi and mine peaks at about 85 psi on high revs and then does drop, is this my issue and if so anyone know the cure, never had too much oil pressure before and it only seems to leak out when driving hard and is fine when cruising around.
