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. |

Oil starvation makes sense. More to come. The question will be how to address it without breaking the bank..damn, I was real strong this year. Keeping up with all the Caymans and gt's.

The question will be how to address it without breaking the bank... Well, if one were to work on the baseline assumption that it is actually oil pickup starvation... - Slightly Improved: Tuna can. Didn't see above if you're running one now. - Better: Type 4 1.5qt oil sump. Watch for ground clearance, though. - Best: dry sump. The CB Performance bolt-in dry sump pumps are not hatefully-priced, all you'd need to do is engineer a tank someplace in the chassis/engine compartment and plumb it. And it doesn't have to be 10-12 quarts, I'd suggest 4-5 should be more than enough... |
