To my surprise I could get 50 lbs of oil pressure with just the
starter! Did reveal on small oil leak around the banjo fitting that feeds
the redrive. I'll mount a temporary fuel tank today. Cant wait to hear it (I
think)

I would expect to see the relief pressure cranking with the plugs out.
So, perhaps 71 PSI cranking.Might fall off quickly when cranking stops.
Oil filters today (spinons) are proof that it is hard to escape your
history. In 1955 the oil filter was a paper or metal bound cartridge. It had a
little bail on top so you could hook onto it with a bit of wire and pull it
out of the thick walled steel canister that was held onto the block with a
long hollow bolt.
This arrangement had a number of features. Every one of them bad. But
since everyone did it the same way, at least you knew what to expect when
changing filters
Put a big pan under the canister and loosen the big bolt. Come back
in 2 hours, and most of the oil in the canister will have leaked past the bolt
seal, into the pan.
Whack the canister back and fourth a few times with a mallet. Lower the
whole mess into the pan.
Fish out the element with a piece of wire. Hang on to it a while to
be sure you have the correct replacement.
Remove the long bolt. Recover the cardboard seal under the head of the
bolt. Even though a new seal comes in the box, it will leak. Only the used one
will seal.
Clean up the few gallons of oil on the floor around the pan.
Carry the 1/2 full bucket of gasoline way out back and scrub off the
pieces, particularly the canister.
Assemble the clean pieces along with the boltand replacement element.
Install with a bit of grease on the threads.
Note that the upper seal ring in the groove where the canister pretends
to seal against the block.It is nearly in two pieces already.Now over
tighten the big canister bolt so as to complete the job of shearing the seal
in two.No need to feel bad. it was going to leak anyway.P.S.there is a new one
in the box, but it will leak as well.
So by now you are inventing the spin on filter element only weeks behind
the big three. And Shazam1956 and the spin on filter is here.
Note that the oil flow in the canister is from the hole in the block
(Next to the oil pump)(Outside the element
to inside the element and then up the hollow bolt into the oiling
galleriesinside the engine.And there is the key to oil flow around spin on
filter elements.
Nothing changed.............................Now you throw the canister
away with the element left inside. You should cut open the can, and cut the
element loose from the end plates, then lay out the media on a new piece of
poster board, and inspect it under magnification and a strong light.Look for
bits of hose. sparkly metals silver and copper.
But still nothing changed. Oil flow is always outside to inside though
the element. Same as 1955.
So how can you get a zero pressure start up on a new engine?
First let us suppose you reversed the pressure in and out hoses on the
remote filter mount.Next forget that nearly every element has an anti
drainback valve.
Look through the little holes around the top of the can. inboard of the
sealing ring.See a black rubber flap?
Why yes you do. That is the oil anti drainback valve.It is there to keep
oil in the can over long periods of time,
where oil would run backwards out of the topand back into the sump. This
leads to a pump loosing its prime.
And a dry start with bearing damage(And pump wear)Note here that many
manufacturers persist in mounting the spin ons in such ways as to encourage
this problem. Inverted or sideways. DO NOT PUNCH A HOLE
IN THE CAN TO LET AIR IN. MAZDA MECHANICS DO THIS. The
hole lets in paint chips, dirt and anything else, right into the center
hole(runs into the rear main gallery and the dowel gallery to the front
main.
So now there is no oil pressure because the rubber flap is closed over
the little holes as a one way valve, and nothing can get through the can.No
problem.
Reconnect the hoses to establish outside in flow All is now well.
There you areGot all of that oil flow stuff, and it was free. Never hesitate
to pull a hose off and hang it in a clean coffee can. to actually see if oil
comes OUT of that hose
I swear that I will never put a Fram filter in anything. I will never
give a Fram filter to anyone no matter how desperate they pretend to be.
