351/400M oil feed

Postby oddfordjunkie » Sun Dec 16, 2012 5:39 pm

I do a TON of research on items pertaining to my truck. Pertaining to the 335 series of motor, it was the only motor series where Ford had the oil feed the Cam galley then down to the Crank galley (others feed crank first) this results in the last main/rod set in the motor being starved for oil.

Easy fix. These motors were equipped with 2 oil sender port locations. One at the oil filter housing the other at the rear of the block directly behind the intake manifold. In order to solve the starvation you run an oil feed line to connect these two ports, this effectively eliminates the pressure drop toward the rear of the engine and gives plenty of oil to the rear main/rods.

With spending less than $20 in the plumbing section of the local hardware store you add years to the motor.
