I have a 1973 MF135 diesel with the AD3-152. I bought it 13 years ago with about 200 hours on an engine overhaul. I noticed it smoked some then, but it started immediately and had good power. It still starts immediately but has progressively gotten much worse with oil smoke to the point I had to do something. Now the motor was overhauled by a local car mechanic and not a diesel mechanic. In talking to other locals in the area I found that he is cheap but not a good mechanic. The fact that it started and ran good led me to suspect he didn't get the oil rings in correctly as to why it had so much oil smoke. Anyway, I torn into it this week and found that there was a lot of things done wrong such as the front crankshaft oil seal in backwards and the rods put on the wrong side of the crankshaft. What is worrying me is that the rear thrust washers were laying in the oil pan and the front ones were in place but pretty worn and ridged. In the pictures you can see how worn the crank is where the washers run and the rear surface of the rear main bearing looks worn to the point that I wonder if the tab on the thrust washer can engage it. There is another picture of the front counterweight that was worn down because the crankshaft was going to far forwards. Do you think the rear main bearing and counterweight are still okay to use? The last picture is of he piston oil rings. They were so tight that they were not able to move freely. The one ring land has three rings over the top of the spacer spring but I thought there was only supposed to be two. So do you think my crankshaft is ruined? If one ruins a main bearing cap does one have to find a good used one and line bore the main bearing caps?
