BMW M52 Engine For Sale

The M52 family was introduced to replace the previous M50 engine family.
The general characteristics were the same as those of the M50 family. We find therefore the architecture to 6 cylinders in line and the system distribution variable valve timing VANOS, with double camshaft in head and with four valves per cylinder.
Apparently it was therefore a family of engines not very dissimilar from the previous one (even the displacementswere the same), but actually concealed many innovations, the main of which consisted of the monobloc in aluminum alloy with cylinder liners reported in nikasil, in place of the integral cast iron liners.
In some markets, especially the British one, a fuel rich in sulfur components was used, such as to bring these engines to premature wear due to corrosion of the nikasil liners. This problem was solved by the parent company in September 1998, even if, albeit to a very limited extent, this problem came back from time to time.
In 1999, with the introduction of the M52TU series, the M52 family has adopted the new Bi-VANOS distribution system (in Italy also known as Double VANOS ) and the electronic “drive by wire” accelerator (including a traditional spare mechanical cable, acting in the event of malfunctions; it will then be eliminated in the next M54 ).
During the course of its production, the family of M52 engines was divided into several versions, different from each other by displacement.
