1986 f250 6.9. Oil leaking from the rear of the motor. I heard rear seal leaks aren't common on these motors. It only leaks under pressure and the stock dash gauge stopped reading so I think its the sending unit.

I got a banks turbo installed so does anyone have any tips or tricks to reach the sending unit? I have an aftermarket oil pressure gauge installed but I had to use one of the oil ports on the driver side cause I couldn't get to the stock sending unit (though I didn't try that hard)

Just wondering if anyone else has gotten back there with a turbo installed or am I gonna have to remove the whole turbo. Thanks.
