I suppose some seal in the PV assembly has gone, allowing exhaust to escape into the forward housing of the cylinder.
I doubt it has a negative effect, but I would be looking to fix the seal before it gets any worse. Someone with more experience will chime in.

From a quick diagram search I discovered I have no experience with this style PV.
