288 cu in. 1948 engine. Is there a way to clean out the oil pressure lubricsting system.
I had the engine running last year briefly. I saw no oil pressure so I shut it down. I finally got a little pressure 4-5# on turning over the engine. I still have problems getting it running. I’m ready to tackle the job,again I stopped for several months because of frustrations.

I'd drop the pan and clean out an sludge and inspect the oil pump pickup. Could be clogged. That should be done on any motor of unknown condition. Also check the condition of the pump to make sure it's not worn or the pressure relief spring is too loose.

Other than that, it's leaky mains, or incorrect plumbed oil filter.

Thanks,
I did clean out the oil pickup
I will double check my oil filter piping
Probably right, the engine has low compression,
How much pressure should I have to run the engine?
