Mechanic’s warning over ‘unfixable’ issue on used | Tech News
A high motoring mechanic has warned of an “unfixable” issue on most second-hand petrol and diesel vehicles offered after 2017. Dave Harrison, a spokesperson for 911 Auto Repairs, pressured the issue may develop into the “next big scandal” in a main blow to these securing a model constructed prior to now eight years.
Dave defined that timing belts have been changed with moist belts in 2017 as a result of they’re believed to be “more efficient”. However, HE pressured the moist belts will seemingly solely have a 10-year lifespan, which means points may begin to come up within the subsequent couple of years. Despite realizing in regards to the issue, Dave pressured that repairs are “very difficult” with motorists more likely to be slapped with pricey payments.
Dave defined: “The next big scandal – wet belts. They replaced timing belts with wet belts on a lot of models after 2017, supposedly they’re more efficient.
“The moist belt is a large downside as a result of it solely has a 10-year interval after which it breaks. It deteriorates and it may stop your brakes working. But if it breaks after 9 years, they don’t need to know. And when it does [break], it’s very tough to repair. It takes twice as long as a regular belt to repair and it prices more to exchange.”
Wet belts are also known as the belt in oil (BIO) system. It means the part has been moved from the outside to inside the engine’s crankcase where it is lubricated by engine oil.
According to GEM Motoring Assist, wet belt systems are said to reduce drag by 30%, which could provide emission benefits as well as save fuel.

GEM explained: “Common issues with BIO timing belts embody swelling, delamination and tooth shredding. All of these components finish up trapped within the engine and have to be eliminated manually.”
However, Dave warned of the potential long-term impacts with the high prices, which means highway customers are more likely to must ditch their automobiles altogether.
He added: “That’s one that makes your eyes roll when you see it – oh god, it’s got a wet belt. They say it’s better but it ends up costing double to fix or it’s unfixable and makes the car basically worthless.”
