Hope some one can help me.I have a buick 225 dauntless v6 oddfire in a jeep my problem is the right head was not getting any oil up to it,so I read and found out that they oil through a port in the front of the block and up a port in the head and into the first rocker pedestal and in to the rocker arms shaft.I took the head off and found that oil port was completely plugged I ran a drill bit through it ( the exact same size) and cleared it of the soft materiel that was in it.Then I bought a new rocker shaft rockers and pedestals assembly and put it in, now the head oils to much and pools oil up over the valve stems and it gets into the cylinders and smokes.I noticed that the rocker arm pedestal that is closest to the fire wall also has the same oil port.One of the questions I have is this a return port back to the crank case or is it just there. Seems like there is no place for the oil to return to the crank case util it gets high enough to flow through the passage ways that are up higher on the head.Or maybe there was some kind it restrictor that I drilled out. The other head dose not push oil out of the rocker shaft through the rockers like this head dose,I have read that the pedestals are interchangeable are the bolts that hold the pedestals down also interchangeable could that be the problem, the oil dose enter the supply pedestal around the pedestal bolt. Please help !
