Mag Case Split?
After reading Wayne's book and searching this forum I have become reluctant to rebuild my bottom end. It seems that if the case is split it will warp. Is this always true? I have A 76 2.7 S R7 case before disassembly it had good oil pressure but 3 pulled studs and the associated puddles. No inserts on any stud hole. Four of the Cylinders were also passing some oil through the exhaust.
I have checked as far as the CR bearings and they have an even gay color with no copper with clearance in the mid range, could have been changed some time in the past.. It is probably a stretch to assume that the mains are the same, 200,000 miles but I have read where 250,000 is the average lifespan.
I have measured the spigots and they are within .004 Inch of round and are all even.
I was thinking of pulling a center through bolt and checking if the hole was round. If it was check another and so on. And if all O.K. finish the split.
Any input from the sages ?
