Re: Engine shagged on brand new 1.4 16V

When I bought my car from new they said it doesn't need running in and can be revved right up to the limit. I asked if it should be 'run in' but was told this is not neccessary as these days they're all run in on the bench. So therefore there can't be such as thing as over revving it, as the limiter stops it revving any higher than it should.

Re: Engine shagged on brand new 1.4 16V

in that situation yes but you can over rev an engine dropping down the gears at high speed as its mechanically induced

it dosent lean out the mixture it shuts off the fuel completly

and another thing it dosent have a throtle control it has an idle controle valve witch canot limit the engine in any way just control idle

Re: Engine shagged on brand new 1.4 16V

i dont beleive you have over reved it with your right foot, droping into second sounds more likely

infact their is a prosedure of reving it to the limiter for learning the phonic wheel sensor on the engine this has 2 be done 2 or 3 times over and dose more good than harm as most engines have been grogeled

if you have induced the engine to over rev then you may have skiped the timing ie jumped a tooth on the cam belt this whould explain the poor perfomance

howether i have never heared of anybody breaking a fiat engine throu reving it to hard except a few cases were it has not been servised and more importanly oil changed or not had any in atall because people dont check it often enouth

i rev my uno to the limiter all the time well just under it and it is set to 7500 rpm and afterwards it sounds much healthier my car dosent smoke or lose any oil atall

if you carry on driving it and you have done internal damage to the engine you will notice oil or water levels droping
ie pistons worn or cracked or head gasket blown more likely the later

if the levels stay normal then i can only gues the timing has jumped

just be glad you dident buy a ford that whould have long expired anything past 6500 rpm

Re: Engine shagged on brand new 1.4 16V

ok people, go back and read..

he revved it to 7k ish in second and then changed up into 3rd.. you know, a higher gear.. so the revs would've dropped, not been forced up.

now.. onto rev limiters,

Quote Quote:
Upon consulting the Owner's Handbook.. it does say

"IMPORTANT The electronic injection control system gradually shuts off the flow of fuel when the engine is "over-revving" resulting in a gradual loss of engine power
gradual, not complete - that is leaning it out. regardless, to reduce fuel is leaning out.

and as for throttle contorl.. these things are fly by wire throttle. the throttle butterfly is moved by a stepper motor, not a cable thats connected the accelerator - all that is controlled by the ECU, so like i said, full spark, fuel and throttle control.

isnt it the st or something else that ford has made that will go at maximum revs for approx 150,000 miles without going wrong, as long as everything else is in perfect order or something

edit: cant find the website i read it from now, may be something totally wrong and just a rumour i hear but if someone else has heard it then let me know :P

I believe those engines also have a cam chain instead of a cam belt, so something else less likely to break!

Question Re: Engine shagged on brand new 1.4 16V

Thank you all for your posts.

I haven't driven it since driving it back from the dearl on Saturday.

It's going in tomorrow morning first thing, I won't take the car back untill it's running properly.

And to clarify I was in 2nd and went upto 3rd.

The main thing I noticed was the rev counter, as normally they're really responsive arn't they?

Anyone with a 1.4 16V when you slightly touch the gas the needle smoothly jumps, then when you take your foot off it jumps down smoothly - not goes as slow as the speedo??

Re: Engine shagged on brand new 1.4 16V

It had skipped two notches on the cam belt (Essential it stays put), massive error on design because no matter what load / stress there should be enough tension for it to never slip!

Since it slipped it's not been right, still isn't right. Engine managment wires are exposed on the connection, also a beeping / clicking sound of a solenoid going off before engine starts and whilst enegine is off.

Exhuast blows / pops. Am not happy. It's going back first thing tomorrow.

Found this on another forum... am really not very happy at all.

"I'm capable of doing it myself and whilst It's OK getting it done on the cheap what happens if it goes tits up and snaps for being over tightened, slips a few teeth and puts some holes in your pistons and bends say 16 valves? Not a cheap job anymore is it and for £193 I don't like to take the chance with something I rely on every day."

Re: Engine shagged on brand new 1.4 16V

I thought it cost more than 193 to change a cam belt.....thought it was more like 450..?

450 sounds like a 5 pot price

Re: Engine shagged on brand new 1.4 16V

cam belt shouldnt have slipped on a new engine. it clearly wasnt tensioned correctly. jumping two teeth could've caused valve damage, but i dont know the engine well enough to say for sure.

Re: Engine shagged on brand new 1.4 16V

Cambelt shouldn't jump. Period.
Fuel cut at the rev limiter is (according to Coupe Technical manual) retardation of the ignition at the soft limit (about 6800 rpm I think on the Coupe 20VT), then fuel cut at the hard limit (7013 rpm on the 20VT).
So it retards the ignition rather than leaning the mixture out to start with.
