Got (some) oil flow.

Remove the pick-up tube and cleaned off Hylomar. Cut a new gasket = out of=20 some gasket stock I had lying around and installed pick-up tube = without any=20 sealant.

Hooked up starter (plugs removed) and spun engine, no joy. Removed = outlet=20 hose and primed pump again. Got oil flow. Reconnected oil line and = left it=20 slightly loose and had oil pressure gauge sender out. Cranked engine, = oil=20 flowed out of pressure sender hole. Let engine set while bat recharged = some.=20 Tried again, no oil.

How fast does the engine have to go = the get=20 oil to suck up the pick-up tube quickly, or how long after starting = the engine=20 does oil pressure come up?

I would add to the other comments that Hylomar should NEVER be = used as a=20 sealant.  It is great stuff but as a seal (O-ring=20 type) preservative.  Also aids assembly by holding them = in=20 place as Ed said.
