Skoda Fabia engine problems

[xbemx]

Hello. 

 

Has anyone had problems with engine (1.2, 2002) runing like this. It seem it is working only on 3 or maybe 2 cylinders. It lost fair amount of power, but is still driveable and the whole car is vibrating. Any  ideas?

Could be a failed ignition coilpack, could be more. Any fault lights?

You know that your engine only has 3 cylinders?

[xbemx]

No, I did know that, thank you  Yes, the engine light is on all the time, but some times it starts to blink. Thank you for answers.

Take the engine cover off and look at the tops of the coilpacks. See if any have obvious bulges/blisters.

Just before time belt - jump? Soon valve crash?

If the engine has gone more than 130 000 km I would be worry?

Mine chain vas gone after that km drive. In Norway this happens often, I have heard. Other here can tell more about it? 

[xbemx]

coilpacks seem ok. it looks like left cylinder is leaking oil...

[Breezy_Pete]

Could still be a coilpack problem, really need to scan for fault codes with VCDS or a handheld scan tool.

Torbo might be right too, timing chain may have slipped

[sepulchrave]

...or burnt valves.

[Breezy_Pete]

Yep, definitely a possibility.

[xbemx]

thank you guys. so the best option is to take it to mechanic and he will scan the fault codes and we will continue from there.

[Breezy_Pete]

Yes. You might be able to hear the effect of a leaking valve as an uneven rate of cranking when the starter motor is turning?

[xbemx]

I am not sure about uneven rate of cranking, but it surely runs uneven. I just did the paper on exhaust test if it helps in any way?

Compression test.

@xbemx - The other possibility I can see here is an oil-fouled spark plug, probably on the cylinder you're seeing the leak from. Without access to the car I can't advise on likely causes of oil fouling in the individual case but @Torbo @sepulchrave and @Wino have all gone straight to worst cases IMO.

[Breezy_Pete]

I disagree, @KenONeill, my first suggestion of a failed coilpack is pretty much the best case scenario. The oil 'leak' evident in the first picture looks to be fairly obviously from careless filling.

@Wino - Are you now denying agreeing burnt valves as a possible diagnosis? Or claiming that spark plugs are cheaper than coil packs? Or both?

[Breezy_Pete]

Burnt valves is a very real possibility on these engines,  it would be foolish to disregard or disagree with that suggestion.

 

But on the basis of doing the cheapest and easiest things first, a free eyeballing of the coilpacks, followed by a potentially free scan with VCDS or a scantool seem perfectly reasonable as first steps to me? Sparkplugs are another good thing to check, I don't disagree with that part; maybe I should have been clearer.

Correct reckoning is a good point - good idea. Diagnose, compression test. Correct order is a good point. Coils is a weakness, so it's a good idea to check with another? Spark plugs can also reveal problems.
Cylinder leakage test is also a good thing to do unless compression test reveals the error.Then think about chain and head. Easy job to change chain if the head must off.

My skoda fabia 1.4 16v petrol 2005 are even WORSE than this and all 4 coils aswell it cuts out all the time its got backfire, smell of petrol and sometimes can't even rev it. Its not drivable at all will change when they arrive hope it is them checked and cleaned everything 3 times
