Is the cap for the right cover? seams like an odd place to leak...
could be the PCV valve or "orifice"
Blow by is from compression leaking past the rings. Its always normal to have some, but to much is caused from rings not sealing properly. it could be from being washed out, broken, worn, cracked, broken ring land on the piston ect... since its an 88 I would just assume they are worn rings.
