::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.

| + | :::Carbon has 4 electrons in its outer shell. It wants 8. It will either donate it's 4, or grab 4. 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. | ||
