chevy 235 question

took apart the motor to put in a new cam, upon putting the lifters and rockers back on i noticed two small oil holes on the rocker arm shaft, not sure if they face up or down. im guessing when the shaft fills up with oil it falls through the holes lubing the rocker arms....facing up or down is the question...

 

i think they go up if i remember correctly

 

holes up makes more sense, thanks just making sure

 

did a search on google and some say up some say down

 

The vintage chevy experts say down, I'd bet the farm on it.

 

55 shop manual says up. why would they lie?

I can't see from this exploded view, but I'm still saying down. Can you link where the manual says up. Interesting

 

I'm convinced,you seem to be right..I would have lost the farm..

 

Maybe I'm farming again. Now I'm really lost.

 

In all practicality it wont matter. the restrictive part is the hole in the rocker arm. the pressure and flow is determined by that. If there isnt excessive wear on the shaft, its fine.

lets ask squirrel

 

ahh im lost too

 

the 3 big holes are for the bolts to attach it to the head, the smaller holes are for oil, not to be confused

 

The oil holes go down. Lets apply some reasoning. If the oil holes were on top, the rockers would be running dry until the shafts fill and the oil starts exiting the top. With the holes on the bottom the oiling starts 'much' quicker. The oil holes on my '38 were down when I pulled them and they are down now.

 

I stand corrected. I just checked 4 rocker arm assemblies and each one the oil holes are down.

 

thanks for the input guys, down they go
