Broken Timing Belt

[Aaron Jongbloedt]

I just went through this; I picked up a '98 a4 w/ 110k on it, were the belt 
went go at idle.  or so the previous owner says.  I ended up replacing all 8 
exhaust valves, had the head refurbished (new guideds, retainers, lapped 
valves), new gaskets all the way around, new snub mount, samco hose kit, new 
diverter valve, spark plugs, all new accessory belts, t.belt kit, new water 
pump, O2 sensor, ecu coolant sensor, all the necessary gaskets.  I spent 
right around $1800 on the head, and a bit less than ummm $2800 as a grand 
total to get the car back on the road.

I have heard of the end of the valve snapping off, bouncing around in the 
champer ruining the entire motor.  I have heard of the valve moving the 
piston off to the side enough to wreck the piston rings. I have also heard 
of a case were one cylinder didn't raise quite as far as the other ones at 
TDC, bent connecting rod?  SO, it is a gamble.

Here is my thread from VWVortex which shows more or less what you may be in 
for..
