smoking crx

[PHOBIA]

my friend has a problem with his second gen crx.
it pores out pure black smoke and is spitting liquid out of his exhaust.
he had a set of bosh dual spark plugs in for about 2 months and in my opinion ive never seen a set of plugz that tore up, looked like they had been burnt with a torch.he sed it started doing it after he installed his a/c . what else would cause pure black smoke to pour out the exhaust?

hmmm, a better stated question.
what would cause his d15 to smoke, burning oil? what else?

Blue smoke is usually oil. White smoke is usually steam, or a blown head gasket. Black smoke is unburnt fuel, or running rich. These are all generalities, but hold true most of the time.

I would check the fuel system, but that is just my $.02 :roll:
