My first choice would be to find a turbo front cover and use the factory turbo return line. My second choice would be to tap into the rotor housing just above the oil pan, on the spark plug side, and run you line there. You must remove the pan to keep the fillings out of the pan. You may have to also drill through the web in the rotr housing (I dont remember if it goes face to face)
My gearbox pump (Moroso unit) does not stand up to the pressures and temps
seen in my RD-1A installation. I have been unable to locate a better pump.
I am almost ready to give up my custom oil system, and connect the engine oil to the PSRU, as Tracy Crook recommends.
Has anyone connected the oil drain without removing the oil pan?
