2000 VW Jetta: Timing Belt Popped & Bent Valves... Got Hope???
Timing belt popped in the middle of the highway at 121,000 miles. We had a new timing belt, serpentine belt, and water pump put in, before we learned that at least 2, may be 4 valves were bent (VW are very tightly tuned and depend on precision timing. When the timing belt breaks some valves may open into the combustion chamber at the wrong time, and they get crushed by the upward thrusting piston). See http://www.alldatadiy.com/techtips/Volkswagen/20050926b.html
We'd either have to redo the head, valves, and pistons, or replace the whole motor... or just get a new car. The fix could easily cost another $1000 - $2000, in addition to what we just paid, without any guarantees.
This is what it means when a timing belt breaks.The valves bend after they
hit the pistons.This is a test i use to determine
quickly if severe damage has occured.A shop may use vacuum or simply
rebuild the head as bent valves become obvious when refaceing them.Valves
of a small stem diameter may not leak as the valve spring pressure
pulls the valve straight enough to seal.
But after repeated cycles of opening the head of the valve will break of
destroying the engine.
Also the valve guides are usually cracked in KIA HYUNDAI heads and the
smalls pieces will go in the engine.I have seen guides cracked in all the
16 valve heads
Cylinder Head 105 - Valve Job Basics
Valves not sealing? Valves not bent? This is how you fix that problem.
In this video I outline the basic valve job procedure. Cleaning the
valves, cleaning the seats, cleaning the combustion chamber and lapping the
valves in to make a better seal.
Here I cover the process start-to-finish. It's the same exact process for
pretty much all non-rotary combustion engines. It takes patience and
perseverance to do this job, but anyone can do it. Reference your service
manual for measurements and service limits. Everything else that's not in
your service manual is in this video.
I apologize for not having broken busted crap to work with in this video.
It's more beneficial to all of you when bad fortune falls on me because it
gets well documented, and many people watching these videos are looking for
answers. If you have bent valves, you will discover it quickly once you
chuck one up in the drill. You'll see the face of the valve wobble around
while it spins. You'll see evidence of this damage on the valve seat. If
it's bad, you may see damage on the valve guides in the form of cracks or
missing pieces where the valve guides protrude through the head ports.
Give all that stuff a good visual inspection. ...and if you doubt yourself,
never hesitate to get a second opinion or consult a machine shop. They
will have access to expensive tools that you wont find in your average
Pruven Performance engine melt down 4 cracked pistons, 8 bent valves.
Pruven Performance screwed up brand new Evo IX after this run the car had 4
cracked pistons, 8 bent valves, warped head and a long list of issues car
had to be taken to AMS for a new engine and head.

Broken Timing Belt damages some Engines without Piston to Valve Interference
(RockAuto.com is a MotorWeek Sponsor) Next to some timing belt engine
applications in the RockAuto.com catalog is the note "Interference Engine."
This usually means the pistons will hit the valves if the timing belt
breaks or slips while the engine is running. MotorWeek's Pat Goss explains
that some dual overhead cam (DOHC) engines are severely damaged by a broken
timing belt even if the pistons do not hit the valves.

Timing belt jumped a few teeth. Checking for possible bent valves. Engine
has compression. Trying to pull distributor, it is jammed in bore, had to
use large pry bar to pry out gently. Later disassembled distributor to
check pickup coil. So far everything looks good. Getting some bad
information from repair manuals. Last person that worked on timing belt
really made a mess, we are trying to straighten up the mess before we
reassemble the engine.

EASY HONDA CIVIC TIMING BELT (DETAILED) CHANGE/REPLACEMENT 1998 1.6L HONDA CIVIC
Automotive Technician since 1991 I show how easy it is to change the Timing
Belt and tensioner on this 1998 Honda Civic 1.6L. Timing belt kit (Belt,
pulley & tensioner) all cost under "$55" for the parts. The procedure may
be different for other vehicles but the principles are the same. The first
tool you should grab is your repair manual, do your research, then attack
it with no fear. Hope this helps you with your project. One day you will
stand before God, make sure you get it right before you do, repent and get
your life right with Jesus Christ, your soul will be required of you God
Bless. Warrior 4 Christ.
