oil crossover fitting

02POWERSTROKE7.3 · May 25, 2011

Going to add a oil crossover on my 7.3. Does anyone know what size oring boss I need to thread into the oil port?

I was thinking they were a 5an oring boss to 6an. Does this sound right?

Can't you just take to check valves out of the pump?

Honestly its not worth the effort. I did it on mine along time ago. And didnt notice any difference. And it just adds the chance of springing another oil leak.

Yes, 5 orb but as said above... just another place to leak oil.
