The information in that article is fictitious and dangerously incorrect. I know both the Peugeot TUD3 and TUD5 very well because the TUD3 is famously a "lemon" engine with many failures and was quickly replaced by the TUD5. I did some of the failure TUD3 failure replacements not in cars, but in Toro golf-course equipment (Toro 3000 Groundmasters). Toros run hydrostatic pump, wheel drive and cutting heads at 2600rpm. I had to record in the Workplace Health and Safety job book (welcome to Australia) the weights used on the engine lifter and the TUD3 is 108kgs while the TUD5 is 114kgs (drained of water and oil). The TUD3 is most certainly NOT 80kgs and that is even a tough weight for a 1.4 SI (car) engine to meet let alone a 1980's designed 4 cylinder diesel. Add to that oil, water and radiator/hoses and you are over 120kgs. I have no more to add to this 'discussion' and wasn't intending to, but post this info in the interest of helping someone who may consider the Peugeot diesel a choice, it's not.
