oil leaking on top of the timing cover

[diymirage]

hey guys 

i bought a 87 bronco today, with a 351W in it but it is leaking oil on top of the timing cover 

the engine has been rebuild with aluminum heads, eddy airgap RPM intake and a wilder cam 

my first thought would be a bad seal on the china wall (possibly due to a lack of PCV system) 

does this sound like a good assumption or should a look at the actual timing cover ?
