Well, my understanding is that I'm supposed to avoid getting oil on the coolant o-rings during assembly. I screwed up and got a fair amount of oil on two of them (an inner and an outer). I'm wondering if I can just clean them up and use them or if I should get new ones. They were installed using hylomar and the lightweight oil that I was using on the side housing surfaces for initial startup got all over them.

Any advice is appreciated.

Most builders hold them in place with vasoline p jelly

 

*some* builders do that, I don't know about 'most'. Hylomar is used by Racing Beat and several others.

But my problem is that I got oil on the o-rings. I've decided to wipe them down and use them. You are right that, whether or not it's most, a lot of builders use petroleum jelly without problems so the oil must not be a kiss of death to the rubber used in the o-rings.

I just thought I remember some kind of warning, maybe from the rebuild video or the RB catalog, against getting oil on the o-rings.

 

Well really depends on how much oil got on them. I would use the outer ones again with hylomar for sure.
You may not want to risk using the combustion ones though.

 

dont worry it will be fine... those seals are strong!!! the onlt thing that kills them is heat!!
