Finally got round to checking the woodrough key today on the camshaft pulley and its fine so im going to put a new timing belt on it for piece of mind because it looks like the original one but now im clueless to why the cars still smoking and why it wont rev above 3k
Diesel exhaust grey/white smoke often indicates valve/fuel timing issues, water contaminated fuel, engine coolant entering combustion cycle, insufficient fuel supply, blocked DPF, low combustion temperature i.e. EGR valve open, unburned oil entering the exhaust flow and last but not least a worn or flood damaged engine. When buying a 10-year-old scrap and parts project, the price is what you pay and value is what you get~ or perhaps not if beyond economic repair and you may find it profitable to do additional research; some 1.5dci smoke threads on MSC and additional tasters as follows to get you started?

We look forward to hearing an economically positive resolution and useful addition to MSC archive! Good luck.
