RS4 B7 engine damage

[riddo]

Hi all

I have a B7 RS4 only 70,000ks, it appears there is a deep scratch in cylinder wall, no idea how this happened. They are suggesting that i may need a new engine - or bottom part anyway, as the coating will be too hard to repair. They are getting a specialist from Audi to check it out, however does this sound right?

Cheers

Sounds like a screw from the intake manifold flap runner has loosen and fallen into the cylinder. Plenty of info online about it happening to others.

Not good news.

Can you machine and sleeve these engines?

Not common at all. Especially in Aus.

I believe LA Sleeves and maybe Darton sleeves have one that fit.

Unfortunately I can offer some first hand experience with this, had a scared cylinder from what was most likely a melted spark-plug.
Looked at sleeves but with the man hours and accuracy required was simpler and cheaper to get a 'new' block from a wrecker.
Unless you want to rebuild the block with forged components etc, I suggest doing the same.
SC or NA?
Sorry.
