Default Oil gallery plug

Saw this on Ebay. Why this as opposed to countersunk plug

That is the front oil galley plug. I have to admit that is my listing...... I had them made to the Ford engineering release drawing for the Part. I have to admit I do not know the reasoning for the shoulder. Maybe a engine expert will chime in..

PS they are available through the link below as well as they are available through Van Pelt Sales.

I thought it metered the amount of oil past it, perhaps to the water pumps maybe.

Am impressed that that you had them made not knowing why. I am sure that an engineer at Ford knew why. I have never seen them before.

Hmm. Small leaking at front seal. Could it be?

Would a plain plug cause low oil pressure? Just wondering.

I would suppose that setup is a "stop" for the oil-pressure valve/spring in the valley on the early units and the "groove" allows oil to circulate between the front main and the front cam feed hole, w/o that groove I believe the oil passage would be completely closed off.

Thanks, Gary in N.Y.

P.S. I'm just guessing on this scenario based on the photo of the plug, we rarely build any early units any more! Most are the 8BA style nowadays!

Old Henry put that special plug in there for a good reason, and it just amazes me that most of the knowledgeable folks here on these engines and those who are in business rebuilding these engines have no clue why that extended diameter is on that special plug. I can remember posting this same question over 10 years ago here on the Fordbarn when Shelly ran this, and no one could tell me for sure back then. I'd put my money on what Big Job is saying.

The oil gets to the timing gears via the flat in the relief valve seat,

The 8BA I'm in the process of rebuilding had a plain old brass pipe plug.

The 8BA engines have the oil relief valve in the oil pump which is likely why they dint have/need the shouldered plug

I'm sure enough oil sprays out from the from main bearing to lubracate everything quite well. you don't need a leakage from the grub screw.
