So his logic isn't 100% correct, when he states that engines started failed right after they went from double to single bearing....
in 2000, porsche started using the single row. not every engine had a single row until 2002 MY, so it's possible that 2 cars of the same MY (2000, 2001) have different bearings.

he also said that there were more failures from single row than double row, which i think has been shown to be true from others who have worked on this. doesn't mean the double row doesn't fail, just that the single row fails more often.

remember, statistics don't matter to the individual.

My apologies if I missed something in Pedro's video. With the DOF, the filtered oil enters the unsealed bearing through the orifice in the flange which I really like.

Where does the oil go after running through the bearing? Does any pass through into the IMS or does it simply return to the sump?

BTW I think it's awesome that folks like Pedro and Jake have given us these options that allow us to stop worrying about this IMSB nightmare.

Thanks to both of you!

With the DOF after stream of oil is shot into the open-ended bearing, it runs down back into the oil sump to be picked up by the pump and the path starts again (sump->pump-> filter-> oil cooler-> DOF-> beraing-> sump....)
Happy Boxstering,
Pedro
