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? |

Ok but the only thing that gave me doubts about the White Lithium Grease in a spray can is that it says it's for metal to metal, and the ingredients are mineral oil, hexane, propane, isobutane... which I thought would be similar to acetone and dry rubber out.

OK, perhaps 3&1? Engine oil, WD40 & CV grease are all petrolium based, which breaks up rubber over time. I don't know what's in 3&1. I like the sound of the marine sealant... sounds like a type of plumbers grease, which is also OK for rubber. (IMG:style_emoticons/default/cool_shades.gif) |
