Hello

Took my 56 plate ST3 in for its 4th service last week. Drove it in myself, all was fine. Left it on road outside and went home.

Called dealer at 3pm to see when I could collect. They then informed me that the car needs a new engine as the crank was worn due to no oil. Some facts to consider:

1. Car has full Ford service history and has never missed an interval
2. Oil pressure gauge was fine and no oil light
3. Absolutely no noise which would suggest a worn crank. I think I would notice it, even more on boost.
4. The car was left outside which meant dealer would have to drive it from road into garage then out the back again. If there was even a suspicion of a crank issue I wager that it would be left outside after being started and I would be called ASAP.

I have my own suspicions on what has happened which has been validated by a Ford mechanic. However, some views from fellow ST owners would be good as I have an idea that the dealer may try and claim there was no oil in it when I dropped it off.

My lease company has commissioned an independent investigation of car, so left in limbo (since last Weds!).

Thoughts appreciated!!

I take it you cant vouch for the oil level in the car? lease car or not I would still check the oil myself on a regular interval.

That aside do they know its a lease car? maybe they think they can pull a fast one or could it be its been thrashed round the block by an apprentice??

Or even worse they forgot to put oil in it after servicing - I hope not.

thats what i thought ,then they took it out for a test drive and ragged it

is it too late to check mileage,do you know what the mileage was when taken in for the service, and average fuel consumption etc

Average fuel consumption can get messed up anyway during a service if they leave the car idling to warm it up or get fresh oil circulated etc.

I'm amazed how they've diagnosed a busted crank so definitely without actually opening up the motor.

Not knowing the reputation of the dealer I too would wonder if they'd run it with no oil in or something like that

As you make no mention of ever having checked the oil level it seems quite possible that there could have been a latent problem due to lack of oil.
Difficult to comment further though without knowing the exact circumstances under which the dealer considered there was a problem which needed to be investigated i.e. had he even commenced the oil change at that point? Worth checking before anything is stripped whether the oil in the engine is fresh or old.

Its going to be hard to prove there was oil in the engine when you dropped it off, i normaly check mine before and after a service.

I agree with troy, how can they diagnose a worn crank without stripping the engine?

Im pretty sure this happened to someone else on here a while back. From what i know you should hear knocking coming from the engine if the crank or shells are worn. But as the others have said you cant really diagnose without stripping it.

They forgot to add oil after the change, simple as. You would damn well know if your crank had gone. I take it that they had carried out the service by the time that this problem was diagnosed?

If you dropped it off in perfect working order then surely it should drive away in the same working order, post service. Something doesn't sound right to me. Its good you've got the independent assessor, if not I'd be seeking legal advise definately.

Coming from the Impreza world, I had often heard tales of new engines needed. I myself needed a new engine after a similar diagnosed problem. Dealer sorted under warranty fortunately, but the point of my post is that noise was very obvious for at least a week and they did have to strip the engine to diagnose, and I haven't heard of anyone developing a worn crank in a day.

Might sound silly, and I'm afraid I don't know the oil capacity of the ST, but the Impreza took less oil than was in the supplied can, is it possible that there was maybe too much oil put in and this has caused the oil pump to go bust??

Not sure about the ST but usually they overflow when they get hot, causing oil over a hot engine, causing fires etc.
Cant see it would bust the pump.

If it is the oil pump this would not cause the sump to be dry of oil, There wold be plenty. I'd worry about the top half of the engine as no oil can get there if the pump fails also the turbo also would be
as the oil pumps directly to it.

A broken pump can cause a Crank failure as there is no pressure. The oil is pressured to the big end shells (which wrap around the crank). Regardless though, you would of noticed this long before it went in.

Not sure where you stand if something fails at around the same time as they have got it (out of coincidence) id imagine its legally their fault ?

Did you have any luck after?
