3.6 Pentastar oil pressure sender woes.....
My sensor was an Amazon special...(had same results with the old oil) I should have saved the old one! If you could install a 4" male to female standoff tube (in the same NPT thread pitch) into that cooler, you could bring the sensor out from underneath the intake and have it out in the open for the next service. Oil temp not so much as its angles upward. Is the wire They can make plastic any texture internally as long as they can E-weld the 2 halves together (cant do a hollow casting) and plastic is very stable with gasoline. Edelbrock makes a performance intake out of plastic for the Ford Coyote IIRC. Remember MPFI intakes can be smooth as a babies butt internally because the fuel is administered at the end of the runner. It can also be in the shape of Mickey Mouse and still work as its only directing lightweight air, not heavy fuel/air mix that doesnt like turning corners.
