Paul mentions turning the engine to get oil to the top, this is because the older cams are cross drilled not grooved and the hole in the journal needs to line up with the holes in the cam bearing to move the oil to the rockers so you may need to turn the engine over very slowly by hand while spinning the pump to get oil to the heads.

Remember Heisenberg's Uncertainty principle - when you observe something you change it. Your rocker arms are in perfect shape until you take them apart and look!

Good point!  Tongue

Tim, one question, what is the best method for turning the engine over by hand?

Nate:

A couple of points.  I think '56 had the grooved camshaft, so turning the engine shouldn't be necessary.  Secondly, you only have to put a screw in one plug in the rocker shaft, because once you pry the first one out, you can use a long rod to drive the other one out.  New ones are available at your local parts store, they are small freeze plugs.

Thanks John,

Glad I have the groove...groovy!

What is the best way to turn the engine by hand just to be sure it isn't siezed up and be sure no valves are sticking?

Thanks for explaining the plugs at the end of the rocker shaft...I was wondering about that.

Cool!  That is what I'm used to but I'm always a little worried about breaking that bolt...I've heard horror stories...

Well, one thing you can do is to use a torque wrench and set it to the torque for that bolt. Use the torque wrench instead of a breaker bar to see if it will turn over. It should require far less torque than that required to fasten the bolt to turn the engine over. That way you should not break the bolt and if it does not turn over then it is probably stuck.



Or, to put it in another perspective, I'm 130lbs. I can turn mine over with the truck in gear using a breaker bar with one arm. It takes two arms for me to torque that bolt. So I'd say if it requires more than one arm to turn over, it's stuck.

Perfect, thanks for the extra advice Charlie, I'll move ahead with the one-arm test approachWink

I've taken the plugs out and turned it by hand before.
