I'd say fuel is leaking past the rings... maybe running a bit too rich?

Pull a plug and see if it's got black deposits on the tip.

if u can get access to an external fuel pressure gauge (not one for your car, just a gauge on a hose) u can check fuel pressure while its running, maybe your FPR is at fault, if pressure is too high, that could cause problems like that... the rings are a good suspect as well, but u'd think if it was that bad it would be burning enough oil to notice...

You could have an injector(s) being held open to long by mechanical or electronic fault too.... lost of possibilties
