Sleeve ORings Question

maxazillion · Feb 5, 2015

I am rebuilding my TO 20 engine. I read somewhere in the archives that you should not use vaseline on the orings for lubrication. The manual says to use vaseline. Any recommendations on this. Thanks for all replies.

I use Vaseline. I know people that use 85/90 gear oil. Vaseline is not as messy.

80 hours ago on the wife's '20 it got vaseline.
35 PSI oil pressure @idle warm or cold.
Replace the seals on the oil tube.

I used vaseline to install the sleeves on my TO20 in 2001 and its still doing fine.

How about engine assembly lube? Not particularly expensive, and available at any car parts place.

vaseline is even less expensive and available at
more places. . .just sayin'

the reason is that those o rings can swell up due to using oil on them. you want to use something that wont affect the o ring. I have used brake fluid and liquid dish washing soap as the best choice.

My favorite is a good thin coating of a silicone lube such as dielectric grease. It will protect the o-ring and lubricate it as the metal expands and contracts much longer that most petro based lubes. Also the assembly is easier, because of the superior "slipperiness".

try using o-ring lubricant. that is what it is used for.
