The weight of the M43 engine according to the catalog is 138 kg. The M43 engine number is located at the junction of the block and the oil pan. The main problem of the unit is not in reliability, but in low power characteristics. You will learn about the failure of the DISA variable geometry system by crackling and noise. Oil leaks from under the valve cover are often encountered, usually due to a gasket. The crankcase gas recirculation valve gets clogged, and the pipes supplying antifreeze burst. With cheap oil, the camshaft wears out quickly, and the hydraulic compensators make knocking sounds.
