Ok, I'm putting parts of my engine back together and I'm using some old rubber parts that are in good shape- but I'd like to lubricate and protect them.
For example- I have the rubber O-ring right under the oil filler neck. Don't have time to run to Pep-Boys again today so I gotta use something I've got. The choices are: *Engine oil *CV joint grease *WD 40 *White Lithium Grease from spray can *3in1 Houshold Oil Or I probably have lots of other stuff that would apply. I just don't know what dries out rubber (alcohol? acetone?) that I should avoid, and what I should use, if anything. Also, I have wiring boots on the outside- what to use on them? |

I'm a fan of silicone grease as it is easier on the rubber because it is not petroleum based. I agree some o-rings are designed for oil contact but I still coat with silicone grease. Pool stores have it readily available.
