[Chevelle-list] Vacum update

[Jim & Chris]

After closer inspection and noticing the valve with the broken pushrod had not closed, so I pulled the head off to find the same intake valve was stuck open ? I brought it to the machine shop that done the work last year  and he said the valve was scored and got stuck. He put a new valve that worked fine.I bolted/torqued the head back in this evening and tomorrow I will put all the pushrods ,rockers  back in there previous slots . then I will bolt/torque the intake manifold and re- attach all previously disconnected components.And if I get it to fire up and run healthy I'll be "shouting for Joy" because this was a pretty big deal for me . you guys are encouraging !

  I had just about the same thing happen to me.  My push rod was just bent, not broken.  The heads needed a servicing, which would have cost about as much as new heads, so I bought a set of World S/R heads which were only a bit more than freshening up my old heads.  They should be a bit better for performance as well.  If your engine is built up more, there are other heads that might be a better choice.  We left the cam and lifters as they were in good shape still.

    I just found the problem .It seems the intake lifter on #7 must have failed causing the push rod to bend like a slight "S" and break off . so now I'm going to take the manifold off to retrieve the lifter and bottom piece of the push rod and look for damage. is there anything else I should do while I have it apart ie.change all the lifters and pusrods ? Thanks again Guy's, Jimmy C.
