how does oil get to valve springs and lifters

[Don]

Started tearing down engine looking for engine noise,think it might be a rod not right .but there was very little oil in the valve chamber galley,i had wipped it pretty dry the other day while adjusting the valves and it was still about the same when i took the intake manifold off,it has been run several minutes and oil pressure has been up good,but varies about 1 lb and holds at about 21 lbs when hot,how does the chamber get oil????

[Don]

i assume the tube in bottom of galley has holes in the bottom of it to dist the oil .the oil pressure spring had some pressur on it when i removed the large nut on top,not a whole lot but some.the plug was behind the timming gear ,i looked when timming gear was off. just about positive the rear plug was there when i put fw on. also no oil was blowing out of fuel pump hole when i removed the fp push rod with engine running

Are the baffles in place in the valley? part # 6524 in the diagram

Splash and vapor deposition

Don'r worry about it, there will be plenty of oil and oil mist thrown up the the spring area after the engine has been run for a time. Walt

If it's a 59ab or early engine there is no oil pressure in the fuel pump push hole. If it's an 8BA engine there is a small pee hole driled through the push rod bushing into the main oil line, you will usually get a mist of oil up the hole if the push rod is left out, not enough to loose oil pressure, most of us plug the hole in the 8BA engine.

Yes the baffels are in place.pulled plugs and spun the engine ,,no oil pressure with spring out,oil come to top where plug goes but no pressure,put plunger and spring in had about 15 lbs pressure maybe there is no problem here,just thought there should be more oil in the chamber,this is a 58ab.

[Don]

59AB sorry. the plunger spring is a lot more heavy duty than the one in a 37 engine i have laying here.Is this ok

most of the above and o-s-m-o-s-i-s...... OLD....BILL

[Don]

dont seem right but i guess it has worked for 75 yrs

on an 59ab eng there is oil pressure in the fuel push rod bushing if you remove the push rod & pull the camshaft foward you can see the hole to the cam bearing oil is delivered under pressure through the cam bearing . if you remove the rod & run an elect pump you must plug the bushing.when you look at the cam bushing there is two holes. the must be lined up right larger of the two holes faces up

There is pressure around the bushing for the pushrod. Not open to the engine and there is no need to plug anything when removing the pushrod. The holes in the cam bearing must be properly oriented so the pushrod will go through. The rear main bearing is oiled by a passage directly from the back of the block from the pump chamber while the other two are from drillings from the oil tube in the valley.

There is no oil pressure to the rear cam bearing, some oil gets by the oil pump and fills the back cover where the cam gear is, there is a slot cut in the back cam jounal and plenty of oil gets to the bearing but not under pressure. There is no pressure in the bushing where the push rod goes, just make sure the bushing is in the block because the main line oil pressure is around the outside of the bushing. Walt

walt explane to me what about the hole that lines up with the pasage going to the maim bearing are they not pressure fed

Yes, on the 8BA engine only, the 59 bushing does not have a hole in the bushing. The hole in the 8BA bushing is only about 1/16, it does not efect the oil pressure, but it will squirt a mist of oil up the hole so most of us old engine builders plug the hole in the 8BA block. Walt

I think that long running at idle will do more harm to cam,By low rpms I think it wears the cam.So listen to the engine run and shut it down.My 2 cents.

[Don]

from what i hear, there is pressure on the pipe running thru the valve chamber,does this pressure show up on the pressure tap where i have my gauge and the sending unit goes? About 18lbs after warm.

[flatjack9]

Yes.

[Don]

took off oil pan removed 7L and 3R 7 is the one where noise went away when i removed plug wire,removed rod caps @ bearing looked new,used plastigage come up with .002 book says .001-.003.where else could the noise come from?, crank was in tollerence also What other noise would go away by removing plug wire?
