Why not just tear it down and put it back together?  Confirm there isn't a problem.  Seems like in insignificant amount of work and money (gaskets?)  to find out if there is a problem before it's installed in the car and then started and the possibility of significant damage and a lot more work.

Rob... I don't read my email daily so I just read your post. The noise you heard ... the first thing that came to my mind was the timing chan. Have no knowledge of when it was last replaced etc. this is obvious a guess BUT since you are turning the crank nut the first 3 places a noise MIGHT emulate from is the bolt/washer or the pulley itself a and then the gears/timing chain. I agree with others reply, the clay would hardly create any problem. When you figure it out, be sure to post your findings so others may benifit.? Good luck. TonytheTiger in southern IL.?

 I'm asking because as I turned the engine toward #1 TDC with a breaker bar & socket on the front damper bolt, I heard a distinct sound that was like something cracked.? The source area was indeterminate.??There was a resistance to continuing with the rotation, but I didn't judge it as a reason to stop.? Applied torque was probably less than 30 ft. Lbs. I dismissed the event as not important until the head was removed to check the valve impressions in the clay. The sound could have been generated be a number of things, rod, bearings, piston rings, etc.? Among potential sources, I have no idea of how resistant to damage a rod bearing position tab is when the parts are only assembly lubed.I probably should defer to being safe and disassemble the #1 R&P from the block for visual & magnaflux inspection or not and take the risk and run the engine as is.

I?m confused.? Why are you asking?? It sounds like you think you have cracks in the pistons because you used clay before and you are considering taking apart the engine.? But you are not sure you have cracks, so you are asking about the clay. ?
If that is true, perhaps the first question to be considered is why do you think you have cracks? ? And if you have them, it would seem irrelevant whether or not the clay was the cause.
