I just completed installation of a Motor Guard (supplied by Ralph) on my 2001 Jimmy SUV . I used a TD Performance Products Sandwich adapter and drilled a 1/8" diameter bypass orifice in the adapter. The adapter does have a built in relief valve. Additionally, Ralph drilled a 1/8" diameter bypass orifice in the bypass filter. I had the local Parker store fabricate series 601-6 swivel hose assemblies. The hose has a 3/8" ID. I am using a WIX FF oil filter.
The bypass filter gets very warm to the touch once the motor reaches operating temperature so it seems that oil is flowing through.
The motor exhibits an across the board approximately 4 psig drop in oil pressure (when hot) after installation of the Bypass. Is this normal / acceptable? Should I consider enlarging the bypass orifice drilled into the sandwich adapter?
Other than the question regarding the oil pressure, I had no problem installing the filter assembly. The most time consuming part was fabricating the brackets required to support the filter. I had to mount the filter just behind the front bumper. This is within 18" of the stock remote FF filter so I was able to minimize the hose length.
Thanks for the help.
