Hello everyone, Ismael53, thinking about this interesting topic, perhaps the solution goes through changing the motor wire before, I don't know how many km the manufacturer recommends lubricant change. I have not observed that manufacturers have extended the change of lubricant in diesel engines, in some cases more than recommendable in my opinion. My father has a BT-50 Mazda, the brand representative recommends change every 15000, we seem too much and from the beginning, depending on the use and environmental conditions (suspension dust) we do not give more than 5000 to 7000 km between each change, always with semi-intentic oil and Liquid Moly additive to the molybdenum bisulfide, the pick up currently has 2300 km Motor, the other every 30000 I make a work to the engine, with a special oil for those purposes (high detergent power) after 10 min running to Resenti, Boto and put the corresponding oil. Recently we took the valve lid, I had a small leak and I was surprised by the accumulated waste inside the engine, we also checked the turbo and everything ok. How many km recommend the Citroen change for Europe and what oil do you recommend?
The other, an experience learned in competition (Chevrolet 6cil 250) The original oil filter was not able to handle the high flow rate sent by the pump (high flow), we realized that the engine metals suffered damage due to dirt and small metal pieces especially probate especially of the motor tachies., And the first question that I asked me at that time is what happens here, what happens here, what happens here, what happens here is. Motor area, supposedly clean ... Cutting oil filter realized the by Pass valve, given the impossibility of regulation of using lubrication systems by dry carter, the carter was modified, the engine suffered pressure drops in pronounced curves, but in addition to this the lack of an efficient filtering of the motor lubricant was being avidido ... In the end after discussing the citation (Amateur with few media, but a great competitive spirit and ingenuity, we woke up many sees trying to put the car on the track), we chose to install a remote filter, out of the engine. They adapted conveniently (there were not much space either), in the area where the filter was originally, we set a piece of aluminum and sent the turner, he made the threads and the clusters to take to the side of the engine, to adapt the filter, with its corresponding base of a mitsubishi canter with its filter, much larger and of greater capacity. I know that this has little to do with the problem in Citroen, but it seemed an experience to share with you, solving a chronic problem, at a low cost of fact before identifying the problem we were several engines, a long time and money ... and the solution was simple and economical.
