No oil being pumped to heads

Post by Ferris95 »

Ok, so I finally got around to putting my 68 ford F250 engine bay back together after replacing the rusted radiator core support. Fired it up after getting lots of new parts (was worried it might not after adding so many new parts!), and I am getting no oil up into the heads. I assume it comes up the hole in the push rods? And it wouldn’t run if the distributor wasn’t all the way down, right? The dist hold down looked flat. I took out the DUI (which it already had), distributor and looked down the hole and I can see the oil pump rod. I took some long extensions and a 1/4 socket on a Milwaukee driver and spun the oil shaft and still no oil coming up. I was so excited to see it run (been over 2 years) and can’t run it with no oil pressure. The dipstick shows full. Any suggestions? Hate to take the oil pan off…

first make sure you spin the drill in reverse , like the distributor turns.
did you have the rocker shaft off ? I think on F E motors there's a tapered bolt in one spot so oil gets to the rockers.

Ok, had it running and wasn’t really seeing any oil into the heads. Had a little dribble out between number 3-4. Same milky looking stuff. Oil has been siting in there for a long time. The two pics show what kinda oozed out after shutting the truck off. Want really coming out during. And bank 5-8 had nothing! Fire the oil come out from the hole I’m pointing at?

This is from memory . So correct me if I'm wrong.
The oil comes up past the rocker arm bolt and goes through the shaft.
one of the center ones , it depends on which side of the engine you're on.
There is a special bolt with a reduced shank to allow oil past it.
I would remove the two center bolts and spin the pump with a drill to see which one it is.
The drill has to spin the way the distributor turns.
Is your drill big enough? I had a corded Milwaukee 1/2 inch and you could tell when it started pumping oil.

keep us posted.

Ok cephalopod, I’l try that. Spun a drill on it for a while yesterday and it was leaking out of each rocker on 1-4 and less on 5-8. Just don’t believe it’s enough to oil everything in there. I’m used to having to put on rocker clips or oil would be everywhere with the valve covers off. I’d love to see a video of an FE engine running with the valve covers off to see how much oil is coming out.

I don't think you get the splash like when the oil comes up the push rod.
It's been a long time since I've been in a F E.
