When putting my 235 engine back together, I noticed that the oil line that comes up to the top of the engine in the middle of the tappets that oils the top of the engine under the valve cover is crimped on top. I checked my old 235 engine and found that oil line is also crimped almost shut. I am wondering if that is done that way to restrict the oil pressure coming out on top of the engine. Does anyone know if that is the case or has both of the oil lines gotten smashed some way. Thanks for responding.

The part of the line that is crimped is the overflow. When the oil passages became sludged up the common practice of back-yard mechanics was to crimp the overflow so the rocker arm shafts would get more pressure/oil.
If you are working with a 1959 or later engine the line is crimped off from new. This forced more oil to the shafts but the grove in the rocker arm was offset so as to restrict the oil flow. It was done in this manner to prevent the sludging problem....but it didn't work.
If the rockers are not getting an excessive amount of oil leave it the way it is.

This 235 of mine is in a 1955 chevy pickup. Does that make any difference?

...NO...

Chevgene, this engine is a 235 in a 1955 Chevy pickup. It has solid lifters if that makes a difference. I guess that I had better leave it until I get it running with the valve cover off so I can see if the lifters are oiling correctly.

The oiling to the rocker arms is the same for solid or hydraulic lifters.
The cars with hyd. lifters have a special oil passage that feeds the lifters but this in no way affects the rocker arm oiling.
Yes, wait and see how things go, the overflow connector can easily be changed later if necessary.

Gene, I have a spare "58" 235 with solid lifters and if I rebuild it can I put hydraulic lifters in it? I see you stated engines with hydraulic lifters had a special oil passage.Thanks.

The 1958 235 solid lifter engines have the same oiling system as the hydraulic lifter engines. The lifters get their oil from either end of the block. The block lifter bores have a passage running from bore to bore. The way to ID this engine for sure is that it will not have an oil line in the push rod compartment. The line ran from the the rear lower corner to the center on top.
It will be necessary to use a hydraulic lifter camshaft.

Thanks for the reply. I will pull the cover and take a look.

Pulled the side cover and no oil line so should be good to go. I am saving this engine for my next project car. thanks again.
