Why hasn't this happen to Trainman and alot of others, Shift at 6,000 rpm and decelerates at the end of the 1/4 mile?????:dontknow:
Trainman puts it in neutral at the end of the 1/4

When our stock engines are at or close to redline and then we let off the gas sometimes #3 and/or #5 cyclinders get starved for oil thus spinning the rod. The exact same thing happened to me road tuning the truck.
Usually, some type of cavitation from the oiling system will cause a main or rod bearing failure. The main oil galley feeds all mains and rods, with #3 / #5 being in the middle?!?
Has anyone been able to determine the #3 / #5 failure issue?!?
Cheers!

Some do an oil pump modification with the spring to bring up the oil pressure/volume combined with a swing arm for the oil pump pick up tube. Our factory pickup tubes are stationary.
You are talking a spring on the oil pressure relief valve correct? If so it would allow pressure over 75 PSI?
Volume would be affected by the gear / rotor style pump and lobe condition.
The good news on our pick up's is the location at the back of the pan, in the deepest part of it.
I wonder if cavitation could occur if you were just a quart low on our 10 quart systems. These trucks can develop some decent G loads for a truck.

there are two types of oil pumps. The first one (2004 and early 2005) is a 3 piece. The second one (late 2005 and 2006) is a 1 piece. The first oil pump pressure relief valve is problematic and will cause a certain whining effect with different oil filter types. Mopar oil filter will deaden most of the sounds.
Be nice to get the exact dates of the oil pumps
My truck does this now. It makes a funky whining sound with every cold start.
But people can determine if they have to much timing your truck will let you know by knocking. It's all about using great fuel an recommended oil,and not dogging your vehicle all the time.
SrtBrad, Thanks for your insight on spun rod bearings.
