    You realize you have to pull the whole engine and tear it down to the shortblock, right?

    Maybe "head" should read "valve cover" though.

    By any chance does this person own a Supra or car powered by a 2jz? It's more than likely just that you're running really rich and the fuel is coming out of the tailpipe in solid, black particulate.

    If concerned about your valve stem seals (which personally, I wouldn't be) then monitor your oil level every hundred miles. If you have leaky valve stem seals, it's not the end of the world, but you will (or at least should) notice a decrease in your oil level. If you keep noticing the smoke as well as a decrease in oil level, then I would recommend taking it to a Subaru dealership or a Subaru specific shop to have them possibly diagnose the problem further.

    That being said, I'd be willing to bet a pretty substantial chunk of $$ that your problem is just that you're running STUPID rich and the smoke is really just exhaust with unburnt hydrocarbons in it.

    Yes, of course, if you had a car that wasn't black you'd be complaining about having to clean all the soot off your tailpipe and bumper every time you wash your car. Being catless with a full atmospheric BOV you will definately see smoke coming out your tailpipe under WOT. It's unburnt fuel. Monitor your oil level for like 600 miles and report back. Don't beat on it unless you have to.
