Disaster :@ UPDATE

[Sammy]

I got my car checked up today for the excessive smoke that was coming from the exhaust, The mechanic said that its because of the piston rings and i probably need a full engine rebuild. I dont know what has causen this must have been the wrong map for the injectors and turbo, Does anyone know how long a rebuild will take? Also what are the symptoms of failing piston rings?
Labour charges what am i lookng at?
This is the worst thing that has ever happened to me  

[Hurdy]

Probably easier and cheaper to get hold of an ED30/Cupra engine and fit it. Cost £3k to do this.

[ktlstar]

The reason was because you was boosting it with no correct map/fueling and timing??????

[Kregiel]

I would agree with the above unfortunately

Best would be to get low mileage engine and swap perhaps and then you would be able to recoup some money by shifting K04 etc

As said, easier to get a K04 lump, its a better engine than the K03 lump anyway.

Something like this?

Shame but as said, maybe because you was giving it beans before it had been mapped?

You really want to get a compression test done unless you already have? If the technician is solely dedicated to your rebuild, it could take as little as 6/7 days, including engine removal and refitting. I'd assume the bores would just need honing. I'd personally go down the rebuild route. Used engines can also be unreliable, at least when you have rebuilt it you'll know it's pretty sound. You could also uprate the specification to support further modification at a later date. I rebuilt my Supra engine in about a month, but most of the time was consumed waiting for machining/parts.

Yeah i have been boosting it around for a while but never knew it would be this serious, Engine swap is definately impossible due to funds.
I have to stick to just changing the piston rings, Is this a going to take a long time? And what should i expect to pay in labour costs?

No Luke i havnt done that yet, What is that and what will it tell me exactly? They have told me it will take 3 days max to do but said £800 labour charge, Does that seem ok?
Also they said because it is a aluminium block they may need to thread some bolts that might not seal back properly which again they said will cost me £50 per bolt, Does this all seem right?

[martziniuk]

Ouch!!
I must admit I did wonder if you would be posting a thread like this when you said you were running a K03 map. Anyway I hope it doesn't work out too costly for you  

[martziniuk]

I just hope it's not scored the cylinders

Sorry to hear this Sammy. I'd be devastated too. I'd contact the many wise old heads on here and see what they would do in your position before making a decision on rebuild v new but used engine.

Id love to do a engine swap but theres no way i would be able to pay for it way out of budget unfortunately

[Hurdy]

It will still be a substantial amount of coinage.  You are looking at £500-1k even if it is just the rings and that's using an independant VAG specialist. This is all assuming that the initial diagnosis of the car is correct.

I know £3k is a lot, but you'll be getting a fully guaranteed, used K04 engine including the turbo, injectors etc and fitted for that price.

I've seen three or four have the same engine swap before for the same price at Statllers.

[Luka]

I'm not entirely sure why they would want to re-thread any bolts, head bolts should be changed as a matter of course, if these are the bolts they're referring to. A compression test is pretty much as it sounds, showing the compression created in each cylinder. This would show if piston rings are worn by having little or no compression in the cylinder. As said, if the cylinders are badly scorn you may need to machine and fit oversized pistons/rings. £800 isn't too bad if you consider what is being done, if that includes honing/machining too. Especially when you think just a cambelt can be £400 odd alone.

I'd say that it certainly must a result of running a K03 map with a K04 turbo, and booting it whilst you're at it.

Given the recent turbo upgrade,I do sympathise and i feel that it must have been really hard not to give it some beans, and I genuinely hope that the £ damage caused is not too great.

Without wanting to knock down the mechanic you're using, is he knowledgeable on the 2.0TFSI? If not, it really may be better to see a specialist such as JKM, R-Tech, Jabba etc, and get everything sorted in one hit.
