Crank was turned an additional 10/10, resulting in 10/20 or 20/10 (had been turned in 1978 I found out). Rods were sized. All new bearings. New Cam. etc etc etc.
Mechanic did the disassembly before sending back to the machine shop. #4 cyl (rod?) bearing was trashed.
Must have been too small of a bearing, bad sizing of connecting rod, or uneven turn of the crank.
Engine went to the machine shop today. Still need to find a way to spend hours getting the transmission to the transmission people. Nobody thinks it is their fault, so nobody wants to make the 2 x 2hr round trips to get the trans moved around. Ugh.
