Hey guys got the old farm truck running today. 48 f5. Got it warm sounds great no noises. Drained the oil out pulled the filter out. Bone dry! What's up w that. Def ran long enough to pump oil and or make some bad noises if not getting any

 

The oil filter is an external, did you check to see if the lines are connected or plugged?

 

The stock type oil filter is a sidestream or bypass filter; about 10% of the oil goes thru it, then drains back into the pan. It doesn't go from the filter to any bearings etc. If let to sit after a run, it is normal for the filter housing to drain down to about halfway full over a period of time.

I assume the gauges were showing oil pressure when it was running?

The inlet fitting on the filter (high on the side of the canister) has an orifice of .060" diameter that wouldn't take much to plug.

 

That is a bypass filter. Only about 5% of the oil goes through the filter and drains straight back into the crankcase. If you remove the inlet pipe I think you will find an orfice there and I'll bet it is plugged.

 

It was very common for that orfice to plug up . Check it out .
