I have had my Stilo Abarth since Jan and been a pleasure to drive. 2 probs that I have is fact that it is loosing a lot of oil (from cam belt side of engine) and Im using 5ltr of oil every 3-4 weeks. I don't know where it is coming from its not the rocker cover because I tried replacing it.


Could the headgasket cause such an oil leak or is there another issue im not aware of with these cars?


Yesterday however the car died. I pulled up to my house turned it off, came back 10 mins later and the car would not start. I wired the car to the computer and got an error regarding the 2 circuits for the knock sensors (I have cleared these faults and they do not appear now).


The car now turns over and that's it.... I took timing cover off and found the issue was caused by a tiny bit of plastic managed to drop into the crank cog and caused the vibrations which set the knock sensor off.


Now Ive checked an I am getting petrol in the cylinders and there is a spark. Could this tiny bit of plastic cause the timing to jump very slightly and cause the engine to not start?


I am going to strip engine this weekend can anyone tell me or show me physical pics of the timing settings for crank and cam shafts.

So ive had a further look and the car is in timing, its got perfect compression, had it linked to a snap on computer and no faults, as I mentioned its got fuel and spark, all fuses are fine Im lost for ideas now please help.

Could the knock sensor still be damaged? It seems like a sensor fault to me?

I thought it could be the knock sensors or the crank sensor but surely it would show up as a circuit fault on the computer??

How sure are you that you have the spark? How did you test?

You will need the tools to lock the crank and cams to do the cambelt.

We had a Nissan van that failed to start. Had spark and fuel but no start. Turned out to be knock sensor but did show as fault on computer.

I have the locking tools etc to do the job. I have now since scrapped the car and bought another in yellow in much better nick.

1 thing I did notice was when it was linked to computer, the old Stilo said 'No' on the key activation but on the new 1 it said 'yes'.

Could a knock on the engine cause the immobilizer to stick?
