440 break in noise from timing cover....we think....be gentle!

Wait/what?
Are you re-installing the engine without having determined the cause of the noise?
What if it's deeper?
like a wrist-pin?
or a foreign object inside a chamber?
What about the water-pump? can the vanes rub? is the shaft straight? What about a piston skirt tapping on the crank?
And I'll ask again, what keeps the cam from walking back and forth in the tunnel? and banging on things. I'm asking cuz IDK, I'm not a BB guy.
I mean I/we didn't hear the noise.......
But IMO, re-installing the engine without discovery, reminds me of the definition of insanity; doing things over and over expecting a different outcome............. well
except for recreational sex. lol
