Oil Pump Belt Failure
 
Hey Everyone,

I have a 2017 Ford Focus SE 1.0L with just over 98k miles. Recently had an "Oil Pump Belt" go bad and tore up my entire engine and vacuum pump. They are saying that I'm going to need an entire engine swap and vacuum pump. Is there anyone out there that knows anything about this?

Just cant believe that this car has a rubber belt that runs the oil pump, and nothing stopping the engine from running when the belt fails. SMH!!

Any help would be appreciated.

What happened to your oil pressure light?, you stop engine based on that and been that way for 60 years.

Suddenly stopping an engine is how an OEM gets sued for millions when a car stops on the freeway to get smacked by others.

We are in a new different world...................

98k is alot of miles for a car thats two years old, you must like driving.
My car turned 4 yesterday and i dont even have half that mileage.

Anywho, the timing belt drives everthing on these motors and is bathed in the motor oil.
So if the belt breaks everything in there likely will.
The oil pump is a variable vane type if i remember correctly.
When the vacuum pump goes it wrecks the motor on these also.
Someone here recently just had the vacuum pump fail on his 1.0 and it wrecked his motor.
So yes, you need a new engine.

What has the dealer said as far as cost or being out of warranty for miles?

He probably lost pressure when the motor immediately stopped.

OK..........vacuum pump is driven off one cam at back end of it. Oil pump is belt driven too. Anything going wrong there lets both pumps stop but the damage likely comes from valves bent when timing belt lets go or simply jumps. A locking up vacuum pump could shed the timing belt by adding too much load to the cam driving it.

Based on what OP says that's likely what happened. If the timing or oil pump drive belt simply broke the vacuum pump would still be OK. I bet pump went bad first and started dragging cam back hard. If the separate short oil pump belt went bad then the oil light would have come on and time left to save the engine. The shop mentioning the vacuum pump going bad leaked out what likely happened.

Almost 100K miles IS a lot for only two years............I learned a bunch tonight about this crappy little engine, enough to greatly reinforce my previous belief that they were short lived crap motors. Let's see how many of them get to 300K miles like the old zetecs used to all day long.

Oil light came on, and everything quickly went bad. Did not have time to shut it off before it blew.

Timing belt was fine, but I did have codes showing 1 camshaft was forward and the other was retarded.

I bought the vehicle last year, appeared to be owned by an insurance company in Florida. Thought that having high mileage should be fine since it was probably highway miles. Clearly I was wrong.

The mechanic did notice that there is a gouge in the oil pump from something being lodged. I assume a piece of metal. But if thats the case then the oil pump had to have been working when something else went (Im guessing vacuum pump). I believe a piece of metal came from the vacuum pump, when it blew, and the piece found its way to the oil pump, got lodged and caused the oil pump to seize and snap the oil pump belt.

Why would anyone run an oil pump with a rubber belt?

Also, found out that the oil pump belt is a maintenance item. Every 150K Mi. Everyone beware!!

Either way, not good. Need a new motor, vacuum pump and oil pump. Vacuum pump is on some serious backorder (HMMMMMM wonder why that is!!!!)

Your codes say belt jumped, they can do it and show no sign of it.

X2 on the 150K rubber pump drive belt, Ford is working actively now to make sure if their cars go 300K miles you have to pay them to get them there.

73k miles on a 2017 focus same issue...

What happened with your Focus, and what did they blame it on?
