On the 2017-2023 Renault Sandero, the 1.0 SCe three-cylinder engine used in the Brazilian Sandero from the 2017 model year has a chronic oil leak at the plastic valve (tappet) cover. The cover's sealing degrades with heat cycles at low mileage — owners on Reclame Aqui describe it as a design defect — and oil seeps into the spark plug wells, soaking the spark plugs and the tips of the ignition coils. This causes misfires, rough running, and repeat fouling of new plugs and coils. Reclame Aqui complaints document leaks appearing on cars with as little as 20,000-30,000 km, sometimes recurring after dealer repair, and related seepage from the timing cover area on the side of the engine. Separately, Renault issued an official recall (service start September 2020) for 1.0-engined units produced July 2019 to January 2020 because a non-conforming oil feed orifice could starve the engine of lubrication, risking seizure or fire — affected owners should confirm completion at a dealer.
Replace or reseal the valve cover with an updated gasket/sealant, clean the spark plug wells, and replace oil-fouled spark plugs and any saturated ignition coils. Inspect the timing cover joint at the same time, as it is a secondary leak point on the same engine. The job is inexpensive at an independent shop; the main cost driver is replacement coils if oil has damaged them. For 2020-build cars, check the official Renault recall portal (renault.com.br/recall) for the open oil-feed-orifice lubrication recall, which is repaired free of charge.
