Do you have any or what kind of PCV system on the car and any valve cover breathers????

Something seriously out of wack,never heard of or seen one blow repeatedly without some major flaw in the system.

I was all ready to take photos but there isnt really anything visible to the naked eye...What i did find that i failed to mention was the intake bolts all seemed a bit loose, thoe one aft on the passenger side very much so? I think it may be very very critical to follow the stepwise torquing and a post relax torque?

I,ve cleaned the whole thing and test fitted the manifold and ther is no preceptable 'rock'...

Are these big stroked 351s in need of very special intake sealing? Gong to talk to the builder tomorrow.

Really frustrating.

I am thinking studs would be better?
