997 Porsche 911 Engine re-build due to cylinder faliure

This 997 Porsche 911 C2S came to us as it had a number of different noises coming from the engine bay, plus there was smoke coming from the exhaust.

We could see straight away the engine was burning oil, the smoke from the exhaust was the giveaway.

We know there is a common issue with nickel cylinder liners on the 3.8 litre engine as we have rebuilt so many of these engines now. But we perform a full diagnostic to be sure of the root-cause.

We used a bore scope to inspect the cylinder liners and pistons. We found 2 cyclinders on bank 2 which had pick-up, this is where the piston starts to wear away at the cylinder wall and this in turn causes oil to get into the combustion chamber (above the piston).

We stripped down the engine to confirm the fault.

The remedy for this fault is to rebuild the engine with steel liners taking the place of the original cylinder walls.

Please see the pictures below showing some of what we did.
