If your rod is indeed bad you will notice you are killing glowplugs and the engine is flaming out. If it was running fine and was not killing plugs you should be fine. I have that same play you refer to in most all of my engines. If you always heated your engine I bet the rod is fine.
yup, that want it is its not eating glowplugs at least from when i raced last weekend and the engine never flamed out on the track it was staying running so it should be fine than.
yea, i heat the engine at first because my box cant turn it over but after that it starts up fine without doing that.
i will take the backplate off to see though if the crankshaft moves in that way your talking about.
i took off the carb and looked at the crankshaft and i dint see any straches on it from dirt or anything .
