Yep it finally happened, someone actually put a rubber band to drive the oil pump that is submersed in oil, see what happens: Ford Recalls 1.0L EcoBoost Engine In Focus, EcoSport For Oil Pressure Issues
"Not even Ford's nifty 1.0-liter EcoBoost engine could escape the regulatory eye of the US government. Ford has issued a recall for certain 2018-2022 EcoSport and 2016-2018 Focus models equipped with the three-cylinder engine and 6F15 automatic transmission. They could suffer from a loss of engine oil pressure due to a defect with the oil pump drive belt tensioner arm."
According to the recall notice, the belt tensioner arm may fracture because the retention caulk joint isn’t robust enough to withstand engine vibrations. If this happens, the tensioner could separate from the backing plate and cause the belt to degrade by losing teeth. If this happens, the engine might experience a loss of oil pressure, which could damage and seize the engine . . .
The recall arrives after the National Highway Traffic Safety Administration opened an investigation into nearly a quarter-million EcoSport crossovers for reports of alleged engine failure in 2018-2021 models in September. Ford’s EcoBoost engines have been under scrutiny since 2022 when NHTSA began investigating issues with the Bronco.
Go view the publics comments, they know it: What genius thought up a belt that would be used IN OIL? Ever see what happens to a timing belt when it gets oily? Disaster. My 05 VW GTI 1.8T has its oil pump driven by a chain. A chain might have cost then an additional what, ten bucks per engine? Sad thing is, you have to take the engine apart to get to the belt too. Why is a gear driven oil pump so hard to figure out? Even mine, driven by a chain is better than this., A small block chevy oil pump failure is rare (the OLD SBC). It takes the distributor locking up to keep the oil pump driveshaft from spinning (That or the cam snapping in half maybe). Now race cars will use a DRY SUMP oil pump powered by a belt, but it's not run in oil, it's external.
