I started putting together the bottom end of my 8n engine today. I got the crankshaft and piston, rods installed and torqued to spec. Then I noticed it had a lot of rod side play. It had 0.018 on one rod, 0.011 on 2 rods and about 0.007 on the fourth. I had the crank turned 0.040 for the rod journals. new liners put in and the rods sized at the local machine shop. My question is is 0.018 too much movement on the rods. I know the spec is 0.004 to 0.011 movement, but sometimes other things still work. I may call the machine shop tomorrow to see if something can be done to correct it or should I just let it run. Any one else run into excessive side play? And what was done to fix it if anything?
