Home-made Push Rods?
I am rebuilding an old engine that is missing a few push rods. I need two 5/16" diameter push rods about 14" long. I can still buy valves and pistons, but push rods are NLA.
Anyone know where I can order some push rod tubing (4140?) to make my own? I can make the hardened inserts, I just need tubing. Or, has anyone ever replaced a tubular push-rod with a solid rod? I know it's not ideal, but this engine will go in an antique car that won't see more than 1,000 miles per year, max. I was thinking of using drill rod and heat treating the ends. Any brilliant ideas out there?

Can you find a pushrod with the correct ends and diameter and weld them to length?

I think SCAT (VW guys) makes a set of 4130, .312 dia. you cut to length then insert the tips. I used these for my 912. Dont remember how long they come, but you could get some tubing and make them too.

Custom push rods are fairly common in the drag race world. You may also find that someone like this can make them for you very inexpensively
