I know the 3.5 head is preferred on the 3.0 transplant in the 350 SDL. Anyone???  |
WIS document# RA07.01-6-0268-10X
injection nozzle: Tightening torque 70-80 NM = (51.6 - 59 LB foot).
Personally on the angled units: I torque them to 30 LB foot, then re-torque to 51.6 - 59 LB foot as needed for leaks.
It is safe to increase torque from 30 LB foot.
Loosening the injector (reducing torque) instantly junks the heat shield.
