R100RT 1990 oil leak from pushrod tube

Pushrod Seal Lube

Just did this job, and another one lies just ahead. . .

Snowbum says to use SILICON Grease on the INTERIOR of the rubber, and on the interior of the pushrod tube (light coating).

Clean engine oil on the EXTERIOR of the rubbers. To my knowledge, NOBODY recommends any type of gasket seal, etc. on the rubbers, or they'll leak. YRMV.

My advice is to wade through Snowbum's tutorial on replacing seals, as there are many valuable tips therein.

Oak sells a complete book/pamphlet on replacing pushrod tube seals...it's a good thing to have if you're doing any top end work. It walks you through the process and provides great step-by-step instructions. Well worth the $25. You'll have to email him to get it... askoak at aol dot com.
 
+1 Oak --

Absolutely, what Kurt said.

Easy job with the manual. Many traps for the unwary without it.

For anyone doing this for the first time: Stay very organized, take your time, and work clean. You're removing (or at least, moving) some large important parts that are going to be moving real quick when they're back together. NO margin for error.

Quite satisfying experience.

glad I asked

I will have to look into the manual. Ok, I backed off on the one cylinder I installed and cleaned the sealer from the rubbers and their holes. I torqued it down, but now I guess I need a new head gasket. :banghead
 
Hey Phil

I figured once the gasket was compressed it could not be removed and reused even if the engine was never turned over. That is an assumption, but a new one would allow me to start over from scratch and get it right with no nagging doubts.:thumb
