No luck today.

 

I filled the line out of the engine just after the pump, then cranked it over with the starter.  I did get a little flow, but not very much.  I reconnected the hose, and added components as I went, checking that I had oil flow after each.  Still had flow after the cooler and just barely a trickle after the filter, where the oil should go back into the engine.  From this I am thinking either I am not picking up enough oil, or the pump isn’t pumping enough oil.

 

The only way I can think to eliminate the oil pickup as a problem is to drop the pan, and feed directly into the engine from a container.  This will be a little bit of a pain, as I will have to remove the radiator, drain the pan, then remove it.

 

I don’t know how to check the pump.  Any ideas or suggestions?  Is there a way to check it without removing the rear eccentric shaft bolt?  It was a royal pain to remove last time, and I really don’t want to have to remove it again if there is another way to check that the pump is pumping.

 

I am not using the apex seal oil pump.  All I did was cap off the hole on the outside of the block, and left all the internal parts.  I don’t think this should make a difference, but thought I would mention it in case.
