Right my oil light came on, pump was knackered, when new pump was fitted and car was started the full workshop was full of bluey white smoke. After about 1.5 mins the engine chugs and dies unless you keep the revs up, if you rev it high where the turbo should come in, my boost gauge never goes above 0 psi! I've been told it could be valve stem seals and piston rings OR that the turbo seals are away. Any ideas cause its driving me mad
