hey guys, would you, or, do you do this? i recently spoke with a bloke who swears by flushing out his diesel engines with diesel. i know there are a number of products on the market designed for flushing and cleaning the internals but hey if diesel works and is safe then why not. all his vehicles are old school non turbo jobs which concerns me a little when i'd be putting it through my 4.2 turbo, not that its cutting edge technology but its the only engine i have. any thoughts?
