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. |

Pushing an engine with low oil pressure and knocking sounds. Sorry but thats just dumb. As for what caused the failure I think Superhawk is onto a good lead. Sure a T4 can push 200 hp with some reliability but it will always need alot more attention and preventive maintenance than a less high strung engine. Changing the oil after every race with an oil analysis is a good start. Measuring is knowing. To me this isnt as much an engine failure as an maintenance/owner failure, the signs were there and you saw them and chose to ignore them.
