End float clearance should be 0.003" to 0.008". Pull off the sump and centre main bearing cap and let us know what you find. Quite possibly a thrust washer has been installed the wrong way around.

Hi John
I had a similar sound after fitting a new clutch assembly it was caused by the new clutch taking up the slave cylinder clearance. After adjustment it was ok
I should of mentioned this before you removed the engine but just read your post however you have the crank thrust to sort good luck
