I have a 2006 Sprinter van with a 2.7 turbo diesel. I'm interested in installing a Frantz by pass filter. Not sure were to pick up and return the oil. Any one on this forum install a by pass on a Sprinter?
I asked Geno's Garage who sells a lot of stuff online for diesel pickups. They basically said it was a solution looking for a problem.
I have a 12QT sump for my Cummins and go 18K or more on my T6 oil.
A failure in a line going to a remote bypass oil filter would be catastrophic.
So slight gain for some risk.
The bypass I put in my car years ago takes oil from the oil pressure sender (i put a "T" in there) and returns it to the pan via a purchased adapter that replaces the drain plug.
Knowing what I know now, i wouldn't bother with a gas engine; your vehicle may justify it;
Teeing off the pressure sender port is good, but make sure your kit contains a restrictor in the line leading to the Frantz. This limits the bypass flow to prevent oil starvation in the engine.
I prefer to route the return through the oil fill cap because it makes taking oil samples so easy. If you're installing a bypass filter then you also want to consider oil sampling.
