Real Gaskets Corp. makes an STC'd retrofit pushrod tube replacement
kit that you can install without removing the cylinders. You pull the
pushrods, remove the old tubes by cutting them in half with a Dremel /
cut-off wheel or whatever and the new ones go in with a spring ala a
Continental O-470 style pushrod tube.

I have a kit on my C-145 and am happy with it.

Real gaskets are out of sight. I make my own from silicone sheet. You
can too and save 8 bucks apiece or just use the right kind of stock gaskets
and a high-quality gasket seal on the valve covers. Cross-tighten evenly
and not too much torque. 20-30 inch-pounds is usually enough.

480 bucks for pushrod tubes? Outrageous. Unless you have money to burn.
No offense to Bela, of course. Just re-swage the old ones on the cylinder
ends. It can be done without removing the jugs. If the leaks are around
the pushrod tube bosses on the crankcase, I'd still pull the jugs and
replace the boots to save $80 per cylinder. Buy you some good clamps. I
use spring clamps. I have never seen a boot get old and wear out, but then
I guess everything is mortal. Even Barnyard Boob.


No offense taken.... I hear ya (and for the most part agree). I
bought the re-swaging tool from (I think) El Reno aviation, and
re-swaged all the pushrod tubes on the left side (port side for you
mariners) of my C-145-2, but one cylinder still leaked. So I only
bought (1) Real Gaskets pushrod tube kit to fix that 1 cylinder (I was
tired of it leaking).

I wish the kits weren't so expensive. I have no affiliation
what-so-ever, but still think it is a superior design than the
original (Continental finally fixed their pushrod tube design
faux pas with the O-470).

A friend just rebuilt a C-85 and sprung for RG pushrod tube kits for
all 4 cylinders. I'm sure he didn't particularly like writing the
check, but wanted to make the engine more serviceable while
it was all apart.... 1000 hours down the road or whatever, it'd
be nice to just compress the spring, pull the offending pushrod
out and replace the seals to fix any future leaks.
