::In any event, in that graphite head gaskets are currently being used or experimented with by some OMs and are also sold in the aftermarket (and haven't to the best of my knowledge come under attack for degrading in the presence of whatever oil they're in contact with ''when being used as a head gasket''), the comment may have been taken out of context. Speaking for myself here, I read the article as much as a warning about using graphite in head gaskets than as a shining endorsement of them, as you infer [[Head gasket#Graphite head gasket|here]]. If any head gasket was put in good light, IMO it was the MLS-types.--[[User:Cobalt327|Cobalt327]] 15:07, 3 May 2012 (MDT) | ::In any event, in that graphite head gaskets are currently being used or experimented with by some OMs and are also sold in the aftermarket (and haven't to the best of my knowledge come under attack for degrading in the presence of whatever oil they're in contact with ''when being used as a head gasket''), the comment may have been taken out of context.

So because it is represented as either +/-4 in a chemical equation, this makes it one of the most reactive and volatile elements. Motor oil has many different types of carbon molecules and other additives that will surely react with graphite. It is my understanding that there are several types of graphite head gaskets, bare, and layered with steel. | + | :::Carbon has 4 electrons in its outer shell. It wants 8.

+ | ::::If that is the case (that motor oil will "surely react with graphite"), and that reaction is such that a '''''head gasket''''' made of/with graphite would be adversely affected by exposure to motor oil during the expected lifespan of a "normal" head gasket, it seems to me that a graphite head gasket might not be such a great idea. So my question to you is, "do you stand by your statement [[Head gasket#Graphite head gasket|here]]", and if you do, are you basing it on empirical evidence or "other" reports? If the source is "other" reports (and is different than the article you cited earlier), I'd appreciate it if you would supply a link- because frankly, I do not read into the article you cited that the graphite head gaskets are anything more than a possible substitute for other gaskets that do the same job as well for less money w/the possible exceptions of applications not yet in service.--[[User:Cobalt327|Cobalt327]] 14:20, 11 May 2012 (MDT) |
