GTI Running in tips - Post rebuild

You can't hone bores on late model VW's as they have a silicon compound coating the sleeve. Honing the bore ruins the coating and kills the engine.

This is why I reckon a re-ring is pretty ineffectual. Not enough bore roughness to force the rings to bed in. Used to have the same issue on BMW motorbikes with Nickasil bores. The fix was to relign them with ci/steel inserts. There was a bit of meat to play with though and I doubt modern engines allow that luxury.

Irrespective of what others have said here, it doesn't matter how you drive it initially, if the tolerances on everything are still too open, then you will still end up with an oil-burner.

I flogged mine in the first 200kms, no oil consumption issues. Others have babied theirs and had no oil consumption issues.

It's just luck of the draw.

In the end that's the conclusion I came to. I'm driving it the way I need to, the car should be able to do that...and if it can't I will part ways with it.

For every tough luck story there is also a successful one....so I tend to agree with Gavs and besides, its not like these engines have zero run in from a manufacturing standpoint.
