So blew up my #3 rod. wondering what caused this. lack of oil, due to rpm? poor return? oil pump sucking air?
last time it was #2 rod. I really don't want to live with this again. Motor specs, Dual oil coolers with full flow plumbing 102 bore by 80mm stroke long rods, ham heads and valve train. Running to 6800 rpm g loads to 1.5 windage tray modified at pushrod tubes for oil flow tuna can with 1/2 extra oil Pics of horror below. First are this failure, then old failure. |

Greg,
Just make sure that you increase the chimney vent some. I went with a -10 AN weld-in bung and a catch can to ensure good breathing. -Aaron |

I've modified the "stack" there to both vent and accept drainback from the can (kinda see it in this photo); it would be easy to toss in a larger vent tube on that block-off plate.
