Ignoring these rules leads to costly major repairs.
Engine: Design features and typical breakdowns
Heart of the majority Nissan Bluebird Sylphy G10 are engines of the QR and MR series, which are characterized by a high compression ratio and a complex gas distribution system. Phase shifters These units operate under high oil pressure, so the quality of the lubricant becomes a critical factor in the longevity of the engine. The use of low-quality oil leads to rapid wear of the couplings and the appearance of extraneous sounds when cold.
One of the most painful topics is the variable valve timing system, which often fails due to clogged oil channels. Phase regulators require constant diagnostics, since their jamming can lead to camshaft rotation and serious consequences. If a characteristic clattering sound appears when starting the engine, you must immediately check the oil pressure and the condition of the filter screens.
In addition, it is worth paying attention to the crankcase ventilation system, which on these engines is integrated into the valve cover. Catalyst often breaks down and gets into the cylinders, requiring expensive replacement and installation of plugs. Regularly checking the condition of the catalyst and using high-quality fuel will help avoid this problem.
