hey guys change all the fule filters on my ute cleaned the lil filter in the injector pump but still blowing greyish whitey smoke.. could this be fuel or turbo!!
Sounds like air in your fuel, try and ditch the primer pump (the one in the engine bay that the filter attaches to) and just put a plastic filter in the line for testing and see if it helps.
Sometimes the diaphram in the primer pump shits itself and lets air in and gives you those symptomes.
