There have been so many failures of belt in oil system that screw up the engine entirely. The benefit is far far less than the problem it has created. These engine manufacturers have lost their mind.

[@AltMarc]

The benefits for the car makers are great, it's called planed obsolescence...

[@A2Z1Two3]

You are supposed to scrap the car before the belt goes , that is 100,000- 150,000 miles . My wife has just bought one of the eco boost engines at 33,000 , and I will make sure we sell it at 99,000 miles . 😮 ( if we are lucky , it will not fail before that )

[@davidperry4013]

There have been reliable belt-in-oil timing systems used in VW TSI engines. However, the best timing is a timing chain with multi-ply chains and low-friction coated metal guides. Timing chains for the most part last as long as you do regular oil changes. The traditional belt-in-air timing systems which have been widely used in SOHC and DOHC engines throughout the 1960s to the early 2000s are designed to last between 60,000 to 90,000 miles and are pretty good too and are easy to replace and a reputable mechanic will check it at 60K miles.

Ford Ranger 2L bi turbo diesel uses a wet belt. After a while bits of rubber come off the belt and block oil ways. Crazy idea they have gone mad! A rubber belt running in hot oil is a recipe for disaster!

[@mazdaman1286]

These belts are letting go at as little as 40,000 miles. Truly disastrous resulting in massive cost or a worthless pile of metal.

1%efficient is not equal to the work when replacing that belt not to mention the price for that belt.

[@claudhenrysmoot7957]

A motor that runs for years is always more efficient then making another motor to replace one that has piston valve party mix. The manufacturers really just want our money faster.

[@Justacogg]

My bet is history will not be kind to these types of belts!

[@bikeman123]

As you can never really be sure your shop is replacing your oil with the correct spec, these belts are just a time bomb. They also cost 3 times more to replace than a dry belt, so many cars will never have then replaced with the result that many will destroy their engines prematurely. Don't buy these cars and manufacturers will stop making them.

[@Tigerfire75]

Hey that is unfair that people won't replace them and it will cause early engine failure. That may not happen. Especially when the belt fails long before it is do to be replaced because it may still deteriorate when not been driven continuously.

BELT IN OIL = MADNESS

[@paulfildes5489]

The total brake failure that my son experienced while coming off the slip road at Junction 10 on the M23 motorway was terrifying and he (and his apprentice) were fortunate not to have been involved in a major accident at this busy junction. The cause of the failure is well documented - the use of the wet belt inside the EcoBoost engine causes delamination over time. Debris from it eventually clogs the pick up pipe and vacuum pump which then fails causing the brake pedal to go hard. The brake pedal simply cannot be depressed to slow the vehicle no matter how hard you try. He is self-employed and relies on his Ford Transit Custom van everyday. It is currently at a Hendy Ford garage awaiting a goodwill gesture from Ford - as it is a few months out of warranty - yet the wet belt was not due to be changed for another 30,000 miles at the earliest.The current estimated cost of the repairs are £1,800! In addition, the failure of the wet belt may have caused damage to the turbo and the cost to replace it would be £1,000 according to Hendy. He has had the vehicle regularly serviced - using the specified oil. Ford have a duty to undertake the repairs - and cover any additional damages resulting from the delamination of the wet belt but they are digging their heels in - offering a fraction of the repair cost.

After watching a recent video of a woman in charge of a small haulage company that purchases dozens of ford transits and saying that almost all of them had to go back to ford due to a wet belt issue, ive become rather cautious of my transit custom now !!

[@joansmith8215]

Back in the 70’s and 80’s, my husband, being a mechanic at the time says that one of the biggest causes of failure with the then new idea of using rubber belts in place of timing chains on overhead camshaft engines was oil leakage from the camshaft oil seal, the oil causing contamination and premature failure of the belt. A particular problem with the Ford Pinto engines. How on earth 40 plus years later have these so called design engineers decided that it’s a good idea to run a rubber belt through a ‘bath’ of oil? The mind truly boggles.

[@VWT5Alive]

At least the Pinto was a non interference engine !

[@WildDisease72]

Belts are made from same companies that make our tires we love

"So what's driving belt in oil technology" A wish and a prayer?

[@Tigerfire75]

It is not a lot of fun changing a timing belt. Add oil in and you are just adding trouble. You don't have to add oil to the belt just make it of better material.

[@phiksit]

Sounds as smart as internal water pumps.

[@TheHungrySlug]

@@phiksit Changing water pumps on most front wheel drive small cars is a whole engine removal and reinstallation. Because there is no room to get bolts or the water-pump out.

[@Jones-xx2gc]

What an absolute genius the person is that came up with this idea for modern cars. I hope the company that person is working for has deep pockets, as I don't see why the paying public should foot the bill for all the failures.

[@cobbler40]

You were right timing belts and oil don’t mix. It causes the belt to degrade and teeth fall off.

[@redjohn20001]

In my opinion wet belt engines are a complete disaster particularly for a used car buyer.

[@Bobby-ez9so]

Any quick online search including KZbin videos will reveal that wet timing belts are unreliable junk. Several European automakers who have been using this technology for a few years have bombarded with complaints from customers of not only premature timing belt failure at the 50-to-60-thousand-mile mark on a belt supposed to last 150 thousand miles but rubber peels from the belt plugging up the oil sump screen causing the engine to have oil pressure loss and shutting down. The oil pan must be removed to clean the sump screen which is costly. Even worse, if a small piece of rubber gets into an oil gallery that part of the engine is oil starved, and you have premature engine ware. To change the wet timing belt, it is labor intensive because many upper engine parts must be removed to access it making it expensive to replace. The 2024 Chevy Trax 1.2 engine uses a wet belt system along with its sister, Buick Envista and owners of these cars are in for a rude awakening. My advice, stay away from any cars that have this very unreliable technology.

[@crow_2k11beatsbydre8]

Proper intervals 5000 km-6000 km or 3000 miles to 4000 miles for oil/filter will reduce the chance of wet timing belt degradation. Owners who experience issues run these wet timing belts without proper oil changes or incorrect oil. These wet timing belts with proper maintenance should last 125000km-150000km or 80000 miles to 95000 miles before required wet timing belt replacement........

[@michaelt.4806]

Here in Europe we call the Ford Ecoboost the Ford EcoBOOM for good reason. Stay well clear of wet belt design engines !!!

[@chriswilliams1096]

The little 1.0l EcoBoom also had the inconvenient habit of bursting coolant hoses. The mass of the engine is so low that the whole engine overheats very quickly and then seizes, before the driver is aware of the problem. Still, the engine is cheaper to make and that boosts (!!) Ford's profits.

[@geoffsclassiccars]

I'll avoid ever getting anything (not just ford) with wet belts unless i can find a way to convert to dry belt!

[@bassmana2z686]

[@oiyou5870]

I won't with the degradation of the wet timing belt timing systems would Shell Helix ultra stop or reduce the damage. Given the oil is fully synthetic GTL based oil with no crude oil base to case any reaction.

[@DashCamSerbia]

It is contaminants in the oil from the combustion of the engine that cause belt degradation. In Citroen PureTech engines what have belt in oil system, it causes the belt to fall appart and chunks from the belt clogging the oil paths in the engine leading the catastrofic engine failiure. So, frequent oil changes and using the premium fuel will extend the lifespan of the belt. Also, all modern engines require fully synthetic oil. Even those that require semi-synthetic should use fully synthetic oils. There is no exuse. It is given that the oil is fully synthetic, why would anyone ever use a subpair oil. And you need the oil that satisfies the quality standard for the specific engine, meanin it is designed for the engines that have belt-in-oil system. Also, manufaturers like Continental and Dayco had released an upgraded versions on the wet belt, that are more durable that the OEM ones from the few years ago.

[@leepower2717]

Puretech = Purecrap or Pureshit as there now known as in the motor trade. Ford Ecoboost = Ecoboom or Aquaboost.

Really? Fuel savings of 1%? It’s a shame to even mention this value. And how much they save on the COGM? Maybe a few cents, maybe 50 dollar / unit. Peanuts! And what about reliability, safety and cost of ownership? Ford is being sued because their EcoBoost engine catches fire due to cylinder wall cracks, and the disintegrating oil pump belt causing premature failure of the engine, and degrades braking power and efficiency! PSA engines, wet-belt disintegrate between two early oil changes on their own, engines need full replacement before they can hit 100 K kms (60 K miles). So that’s how “genius” this wet cam-belt system is! It only brings money to the manufacturer, robbing the car owners and sucking their wallets dry! Wet belt systems are a disgrace for the well established car manufacturers!
