Firtsly, what are the symptoms and how was the cause diagnosed as piston rings?

Basically i was driving 2 days ago in the morning and noticed quite a bit of smoke from the rear i thought its normal and didnt see it again as i hit the motorway, 80 miles later i had misfire from spark plugs.
I then drove to the garage who changed out the spargplugs but by now there is loads of smoke present coming out the exhaust.
After spark plug swap took it for a short drive and realised it started misfiring again, So car got back to garage and pulled out plugs to see there is oil on the tip of the plugs,
The mechanic then pointed out that it is not a faulty turbo (What i thought it was originally) and that it is the piston rings.
This is the where I have come up to with the mechanic so i really dont know if he knows what hes talking about

You need a second opinion from somebody who knows what he is talking about.

Then if its the same outcome, rag it until it finally goes pop while you save up

Then buy a complete k04 lump and slot it in.

Get a compression test done to be 100%.

Agreed but for now got to hope and pray its nothing major!

[Sammy]

What else can lead the oil to the spark plugs? Also do any of my symptoms show turbo failure?

[vRSAlex]

Its not an alloy block on the TFSi engines.

I would look more into the pistons being damaged rather than the rings.  Sounds like you have had loads of det which just ends up melting pistons.

Fair price at £800, but it doesnt really sound like this place knows the TFSi engine very well.

Turbo failure is usually a noticeable lack of power.

Is this the same car with hardware mods recently fitted but not a matching remap? On the face of it I would stay well away from that garage who didn't advise you appropriately.

So what is the block made of in the TFSI? If it is the pistons surely i should go and get S3 ones if i have to change them anyways?

Yes Robin it is the same car with the K04 fitted recently

As others have said I would seriously consider dropping a ed30/S3 engine.  I had issues with my ko3 Gti which had a Ko4 conversion in the end I went to Steve@Statlers and had a low mileage S3 engine fitted.  The car has run like a dream ever since and was the best decision I could of made.

Geordie has a low mileage engine in the classifieds which I would be very tempted by if I was in your position.  I also suggest you take the car to be diagnosed by the tuners who work on these Tfsi cars every day rather than your local mechanic.

Does the engine oil smell of fuel??

I would deffo go with what people have said on here and get a compression test done by someone who really does know their way around these engines. Not wanting to diss your mechanic but it really doesn't sound as if you have had much good advice from the start. It could be anything that is making your car smoke as it is. Is it a constant smoking? It could be down to the map anything. Get the compression test done and dont worry too much until you have a full prognosis.
