Just had a drift event on sunday. Car ran awesome all day. I check my oil pressure after each run. Last run i do i notice no oil pressure and i have oil pressure light. Turn off car and check oil pressure sending unit..just replaced it so thought it failed again..wrong. put car on Trailer took it home. Drained oil. No shavings. Took oil pan off. Found a bolt that connects the oil pickup in bottom of the pan with gold dust everywhere. So no oil was going threw the engine on last run...hope i can get away with replacing the bearings and inspecting crank...or time for another build..oil pickup was dangling there.

 

oh ok

 

ouch

Tore apart the motor. Rod bearings were fine. The main bearings were all bad. Rods and pistons look ok. No visible damage. Further investigation will tell.
