Realgasket pushrod tubes do not require cylinder replacement...unless you have a good reason to change the cylinder too
No Realgasket (spring loaded) pushrod tube on the aircraft. When the replacements start leaking with the new cylinders the Realgasket solution will be installed is my thinking. Don't know if the intake rocker arm is drilled, but will learn soon.

I'm working with an A&P doing an overhaul on my C85 and found that all four of my intake rocker arms were replaced with exhaust rocker arms. All of the cylinders had evidence of oil entering the combustion chamber. I'm looking for three more intake rocker arms to replace the extra exhaust rocker arms.

An honest 20 hours per quart, 1100 hrs since major overhaul with ECI nickel carbide cylinders, new cam and crank. Phillips 20-50 with Camguard. Change the oil every 25 hours. My arteries should be as clean as my engine 😳😉
