Exchange clean intakes ready? That tells you something I guess.
Whats weird, is one owner of a Triton (or a couple in a small company fleet type deal) had his mechanic doing monthly checks on the things, oil capacity not going down on one of them and everything looked good but they did a oil analysis at 50,000k's and the oil was diluted with diesel. Looked a bit deeper into it and the manifold was crudded up, EGR valve crudded up too and not doing it's job properly. Diesel was dribbling in through the injectors and washing down if I recall - lucky catch. Once sorted it was fine, problem never returned.
