The D 2866 engine has been around in various guises for more than 20 years. The two major faults associated with it are a 1990’s reputation for the camshaft gearwheel to come loose with predictable results and a risk of the block cracking along the line of the camshaft if the engine has been uprated significantly. The warning sign for the latter being oil leaks in that area.
Thank you
