Silvertop 2.0
GT28rs
Steel rods
Forged pistons, unaware of compression ratio
803's
Autronic
Standard head/cams
Tubular manifold
Custom inlet / Cossie TB
17psi
Now, theres no breather fitted at the moment, any suggestions or advice please?

Thats a Fiesta not a Escort do i win a prize!!!
Well looking at pics il hazard a guess and say he is looking at 350hp.
It will need to breath well.
I have used the front breather in the block and hooked this up to a cath tank which the rocker cover also links with.

This is my oil breather/catch tank.

This has outlets on the left top corner to the cam cover one in use one blanked for future.
Then the top front face has a push fit for the oil breather filter
then we have the lower threaded fitting which is drain to sump the other fitting is the link to the lower oil breather on block (pictured below)

Looking great there Radders 
With that exhaust manifold there should be plenty space for your mate to use the breather hole on the front of the block, and pipe that and the breather from the rocker cover up to an oil catch tank.
