Ive just removed the turbo pipes to check the turbo and found oil in the pipes before and after the turbo the engine dose not smoke but over boost massivley and cuts out like hitting brick wall at full chatter.I had a bit of oil coming out of the dumpvalve after giving it a thrashing the other day so thought was the turbo but now seeing oil before turbo im now thinking exsesive oil passing through the breather system.Any thoughts on this? It also dose not tick over when warm but drives realy nicely (except too much boost )
