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

SOURCE: Timing Belt Broke. 2002 Volkswagen Passat . Time for a new car?

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

SOURCE: Oil usage in 2006 passat 2.0 turbo

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.

SOURCE: 2000 camry. blown head gasket (daughter drove car

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.

Timing Belt Manual


WARNING Timing belt maintenance is extremely important! The A4 and Passat model utilize an interference-type, non-free-wheeling engine. If the timing belt breaks, the valves in the cylinder head may strike the pistons, causing potentially serious (also time-consuming and expensive) engine damage. The recommended replacement interval for the timing belt is at least every 6 years or 60,000-90,000 miles (96,000-144,000 km), depending on vehicle usage and engine type.
NOTE If removed and reinstalled, the timing belt must be installed in the same rotational direction as removed.

VW Passat & Audi A4 1990-2000 Repair Guide
Timing Belt - REMOVAL & INSTALLATION

WARNING Do NOT turn the engine or camshaft with the timing belt removed. The pistons will contact the valves and cause internal engine damage.


2.0L (9A, ABA) Engines
  1. Disconnect the negative battery cable and remove the accessory drive belts, crankshaft pulley and the timing belt cover(s).
  2. Temporarily reinstall the crankshaft pulley bolt and turn the crankshaft to TDC of No. 1 piston. The mark on the camshaft sprocket should be aligned with the mark on the inner timing belt cover or the edge of the cylinder head.
  3. With the distributor cap removed, the rotor should be pointing toward the No. 1 mark on the rim of the distributor housing. On 8 valve engines, the notch on the crankshaft pulley should align with the dot on the intermediate shaft sprocket.
  4. Loosen the locknut on the tensioner pulley and turn the tensioner counterclockwise to relieve the tension on the timing belt.
  5. Slide the timing belt from the sprockets

To install:
  1. Check the alignment of the timing marks. On 16-valve engines, the mark on the tooth should align with the mark on the rear belt cover.
  2. Install the new timing belt and tension the belt so it can be twisted 90° at the middle of it's longest section, between the camshaft and intermediate sprockets.
  3. Recheck the alignment of the timing marks and, if correct, turn the engine 2 full revolutions to return to TDC of No. 1 piston. Recheck belt tension and timing marks. Readjust as required. Torque the tensioner nut to 33 ft. lbs. (45 Nm).
  4. Install the belt cover and accessory drive belts.
  5. If the belt is too tight, there will be a growling noise that rises and falls with engine speed.
