Car broke down today 3500 rpm coming down motorway in 5th gear then when a tried to accelerate car was just reving

Smoke coming oot the bonnet wi oil spraying oot underneath think the bottom end may have gone

What does everyone else think ?

Where in Fife are you? I would have a look at it for you if I'm close.

I am in dunfermline the now

Looks like oil has been dripping onto flywheel causing it to slip dont lnow where the oil is coming from but will need to strip her down and check all hoses

if its just revving when in gear then you most certainly have a clutch issue - possibly contaminated.

the oil leak should be simple to find

It will be tomorrow that al have a look and strip it down will let you know what i find

Couldnt find where oil was coming from refilled the engine with oil and started it to see if i could see any coming out with no success. Engine system fault came on on the dash when started now has went out other than that the car seems to run fine with no judders clutch feels awryt. Was thinking maybe crankshaft seal or somin but there is oil on top of the gearbox which to me indicates its coming from above the box.

Come to conclusion that the crankshaft oil seal is needing replace anyone had to do one before ?

The crankshaft oil seal, in your case the gearbox end is a lot of work! Essentially you are removing the gearbox, clutch and flywheel just to get at the seal.

Think it will be going to a garage then what kind of price would a be expecting ?

I've never done a Fiesta ST but I would suggest you change the clutch while you have it apart. So for a clutch kit, slave cylinder, gearbox oil and oil seal probably around 300-400 quid at a guess.
