UPDATE!!!!
Today, after letting the truck sit for awhile, I finally got back to work. Pulled the pan. Pulled all rod caps, #2 and #4 rods were babbit, the others .002 inserts. the crank journals all are clean, smooth and mirror-like. Tried removing wrist pins from below. no luck. So, pulled head and pushed #2 and #4 through the top. everyhting looks good. I found that the amount of slude under the pushrod cover differs from the head to the block so I would venture to say the head has been off before. Copper head gasket. The solid lifter in #4 exhuast had a crack just below the lip at the top of the main cylinder, it went all the way around, and deep enough you could wiggle the top. I have never seen that before. So I will match one from my spare engines and replace. I will also wire brush all the lifters and ports for lifters to make sure they are clean, as well as everything else I can.
Tomorrow I will drop off the two rods for machining, and pick up gaskets, shims, inserts( .002) and plastigage for re-assembly on Tuesday. I am planning on running 15w40, because of the rebuild, and it is cold here now. I will probably run it for a short amount of miles, then change to help flush out any debris from the work.
Hope to have her back on the road tuesday night so that I can give my sister a ride on Christmas(She is in from out of town).
More updates to come, thanks for any comments.
