B engine oil priming (1 Viewer)

[Cruising Canuck]

I tried to start my B engine the other day, and it didn't have any oil pressure.

How do you prime a B engines oil? The oil gally side is considerably different from a 3b.
Where can I open up and put oil?

Here's what I got

Did you rebuild the oil pump? People often pack them with petroleum jelly to get a prime on first start up.

You cannot put oil in anywhere upstream of the oil pump. I would take the glow plugs out and turn the engine over until oil pressure builds up.

If you are doing this and getting nothing, use a proper oil pressure gauge instead of relying on the old factory sender.

Nice looking rebuild, nice to see no silver paint on the aluminium parts. What year is the engine?

The oil pump is a positive displacement, it is self priming type. Oil pick up is hooked at the suction, there is sufficient oil in the pan. Check the relief valve on the pump is working. If you remove the valve cover, can you see any oil circulation?
As said above, try to connect a pressuse gauge, turn the engine until it shows something. (No fuel, glow plug out).

So I cranked the engine with no fuel and glow plugs out.
I did it in 5-10 second bursts. Killed the batteries, but did probably a minute and a half of cranking.

There is plenty of oil in the pan, I didn't disassemble the oil pump, but i did replace all the gaskets on the engine.

Anyways, i never had oil pressure indication on the dash, after all that cranking I spun off the oil filter and there was zero oil in there.

A second pressure gauge won't tell me anything I dont already know.

maybe the check valve is shot, ill have to take a look at that. I wish there was some way to add oil to prime the pump

When you remove the relief valve, you have a acces to the discharge of the pump. If you add oil there, it will slowly flow into the pan, filling the pump. It won't hurt.
The oil pickup strainer was clean?
