Hi everyone. First of all apologies if this question don't belong here. Mods feel free to move it if necessary.
Ok. So i own an 09 Renault Laguna 1.5 Diesel Estate. I was driving the other day when the altenator belt broke. Got the car to my local garage where i get my service done to get the belt replaced. Got a call from them asking if i got the timing belt done has they have no record if it being done. i wasnt sure so i told them to get it done. Got a call 2 days later saying that i have a problem with the car. i go to the garage and the mechanic tells me that when the alternator belt broke. a piece of it must have gone into the cover of the timing belt or bend a pulley which made the timing belt to jump and bend some of the pistons. Now the car starts but its super sluggish and smokes likes crazy. the mechanics said to me is because the melange in the chamber is imbalanced or something and is causing the car to only run on 2 or 3 cylinders.
Now i'm not a mechanic or car enthusiast. I know nothing about car but i found it a bit suspicious.
Can anyone tell me if any of it is possible. i thought that in my car the timing belt was under a cover so i dont really know if its possible.
My neighbour told me that if they missed a teeth while putting the timing belt back its would creates similar results like a sluggish start and a lot of smoke has the fuel mix wouldnt be ok in the engine.
Would anyone be able to shed a bit of light on my predicament. the garage now tells me i need a new engine and i dont understand how i went from having a car that was working to have the fan/alternator belt broke and need replacing and replaced to needing a new engine.
All help or advice welcomed. thanks for your time. LP64
