Question about Cars & Trucks
I BOUGHT A 2006 PASSAT AND AFTER I DROVE IT FOR 3 MONTHS IT BROKE A TIMING BELT. WHEN THE CYLINDER HEAD CAME FROM ENGINNERING THE MECHANIC NOTICED WHEN TIMING IS 100 PERCENT THE VALVES HIT PISTONS SO IS THERE A WAY OF SOLVING THE PROBLEM OF TIMING.
That is alot of machining off the head? I would double check the valve timing first, then valve clearances. it that is no good you will have to replace the head and then kick your machinist up the bumb for cutting so much off

i would go with the mechanics advice and allow them to fix it. 1200 to 1500 beats spending 4000 on another motor if that one can be saved

I had the same problem with my wife's 2006 passat turbo. We lost 2.5 quarts in 3000 miles and the warning light came on. They put us on a 1000 mile oil test and I lost 1.8 more quarts of oil. They finally agreed to replace the rings. Service tech told me that the factory rings are defective, they begin to lead after about 25,000.

Yes, you can, but not exactly recommended. If you are going to go that deep into it, then might as well do everything else. However, being unemployed tends to have a negative impact on the wallet....
I suspect it is more than just rings. I think that the walls have been scored badly as well. You may be able to use a borescope to take a peak into the cylinder through spark plug hole. Move the piston to bottom of stroke, and see what you can see. If scarred, much work will be needed. If hatches look alright, then you might be able to get away with just rings.
What kind of compression are you getting on #1 vs #2? This also might be a blown headgasket into an oil passage, or the head (perhaps block?) is ever so slightly warped in this area.
