just a thought but get the injector seat seals checked.
Could possibly be combustion pressure blowing past one and pressurising the system.

if its where I think it is you need to fit a slightly oversize O ring to form a good seal.
If the wells of the rocker box are filling with oil I would imagine the oil is coming up one or more of the studs threads.
