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.
cylinder leak test how to check for bent valves
i did this video to help some of you not get ripped off when buying a
i will be doing many videos of how to test parts and what to look for.
please email me if you have question or what to learn how to test something
else email@example.com or firstname.lastname@example.org
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
Finding If A Timing Belt Or Chain Is Worn.
Scotty Kilmer, mechanic for the last 45 years, shows how you can find out
if the timing belt or timing chain on your engine is worn. It's a
relatively expensive job replacing them, so you don't want to spend all
that money for nothing. It's a pretty simple job checking them for wear,
Once you know how to do it. And, If you like my car help, be sure to watch

First Cold Start of my Passat 1.8T after Timing Belt change
My car was really noisy lately, almost like a valve knock, plus it had
started overheating above RPM speeds above 1750. Those waterpumps were
unfortunately made out of plastic and were breaking off the shaft (my
case). So it was still spinning but slipping at higher speeds.. We realised
that my hydraulic tentioner was all the way at the end of it's course when
we removed the timing belt so the belt had a really big slack, and could
have easily jumped a tooth in the furture. Fortunately with lots ov LOVE
for a VW and patience, and with the help of my friend Marc (BMMRPT), We
managed to do a pretty good job.. il still puzzled why at TDC is my factory
timing off.. meh.. we put it that way and it runs REALLY nice.. so far.
VW TDI Timing Belt with no Tools + Helpful Hints
TDI Timing Belt with no Tools. 03 TDI Golf with 1.9L ALH engine. The
Timing belt broke and took 3 valves(two intake + one Exhaust), 5 Lifters(or buckets) & the vacuum
pump with it. I Used 15/64 drill bit to pin the diesel pump. Got All the
parts(timing belt kit + valves + Lifters + head rebuild kit + odds&ends)
from MetalManParts.com for about $580. I got the Vacuum pump for $190 from
MobileOneInc.com. I got 4 new OEM Glow Plugs from WWW.BoraParts.com for
$45.50. I also broke my turbo GT1749V.
I was going to rebuild it but I would have no way to balance it. If you do
not Balance your turbo it will not last
more than 1 month. That is a lot of money and effort to waste on a 1 month
turbo. I broke my turbo trying to get to the VNTs (vents) to clean
them (diesels are know for fouling the turbo VNTs). I Got GT1749V (center housing
rotating assembly) from WWW.XSBoostturbochargers.COM for only $360. The turbo comes with a VSR report and real balancing
1) Don't forget to put the lower timing belt cover back on before the motor
mount. I wasted 50 mins re-doing the motor mount because I forgot to put
the lower timing belt cover on first.
2) I use High temp RTV instead of thread lock. High temp RTV will seal out
water and remain elastic even after several heating and cooling sessions.
RTV will also stop nuts and bolts from falling out do to vibration.
3) Always check flywheel for Cyl #1 TDC
4) Don't work in the frick'n cold
