ive recently had huge plumes of smoke behind me and on closer inspection of the turbo found there was a lot of play in the axial of the turbo. Got another turbo today and removed the old one, the intercooler pipe had oil lying in the u bend below the turbo, is this normal for turbo failure, do I need to replace all gaskets. Ive also been advised to crank the engine first before fitting the oil inlet pipe to insure its getting oil. Whats your thoughts on this advice. Just dont fancy doing all this again. thanks in advance
