Was in the engine bay (z20let) yesterday fiddling about and noticed my Dump Valve had a tiny amount of oil sitting in it (Trumpet one). When I make it dump, no oil sprays out, but when turned off, you can feel a tiny amount of oil residue is there.
Turbo (VXR Unit) is only 6000 mls old. Is it on the way out?
Or could someone explain what's happening?
