In a typical 50s OHV V8 (Caddy, olds etc) if the oil galley plug in the distributor well is not installed would the engine have any oil pressure; a little if cold, none at all cold or hot?
You should edit and change your****le. Start off (I’m****uming) “50’s OHV Cad engine no/low oil pressure”. Certainly you’re not thinking ahead about wanting to leave something out of an engine that the engineers designed into it.
Really hard to give a good answer to this question as there are many variables. Size of the hole, engine design, oil pump condition, engine rpm, and distance of hole to the oil pump among many. A good example is Buick Nailhead. Leaving that plug out results in no if any pressure.
post from Tony at Ross Racing in 2018: [/QUOTE]That's the screw-in hex plug with a jet hole, aimed at the timing chain. If that is left out, it would be a huge internal oil pressure loss.[/QUOTE] Everybody remembers the 2 plugs in the front of the engine behind the timing gear......it's the one that needs installation inside, behind the small soft plug, in the back of the block , that everybody forgets. It's at the end of the lifter bank in line with the distributor and also weeps a little oil on the gear I get 1-2 calls a wk about this one Tony And a post from Gonzo with pics
My early hemi as an internal pipe plug in the oil galley to....The old racers drilled a .050 hole in it to oil the brass distributor gear that is used on roller cams....Did that on mine and the brass gear shows no wear after 7 thousand miles.....
