I was at Indy in 79 (I think that was the year) when Ron Mancini took his big spill in his Hemi Dart, at that time an A/MP car. Nasty looking crash. Went end over end over the guardrails....

He went past us about the 8th mile and you could see oil running under the car. Next thing you know.....

What happened is that the still pipe nipple that the filter screws on had backed out of the aluminum Milodon pump, thus detaching the filter. I've seen that happen at least twice more over the years..Ronnie McClelland's Bud's Auto Sales 66 Hemi Nostalgia Super stocker did it in the lights at Beaver Springs on a 9.70 pass, giving him a memorable ride through the lights.

Something about that steel nipple in those aluminum pump housings....now, we use loc tite and check it from time to time. In this case, we pulled the pan and checked the bearings, they were fine and he ran it again the next weekend. There is no way we would have run it again without giving it the once over.
