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.

Why does anybody still use belts these days? They are short lived and a pain in the ass (expensive) to replace. Not many American cars if any at all use belts they use chains. Don't know if they still use nylon sprockets, those were notorious for wearing out and along with slack in the chain would skip time. At least they still outlasted rubber belts as well as being easier to replace. Cars nowadays don't give you room to work or need extensive disassembly to replace anything.

Ditto!!! Totally agree. For example my V8 HEMI engine in the Dodge Ram, Dodge Charger, and Chrysler 300C does NOT have a timing belt. So stupid, those things.

Why would you keep it running if it has bent valves, and revving the piss out of it is idiotic.

What I find interesting is you spent money on new rims, taillights, and god knows what else, yet you neglected to perform the basic task of replacing the timing belt at 60,000 miles... now, you may very well need a whole engine rebuild (assuming there is piston damage). Have you learned anything from this?

I suppose exhaust shakes because the exhaust valves open after the pistons pass BDC and start to compress the exhaust gases inside the cylinder instead of pushing them out...then valve opens and the pressure is released violently. you might also have bent exhaust valves. Maybe you should just turn the cam sprocket(-s if DOHC) forward for one groove, but anyway starting or driving car like that is not so clever...

@geicoman5 my jetta just jumped time! my car started making weird noises it seemed like the belt was loose when idling. then i would start it and it would take a couple of times to turn over.. best thing to do is STOP driving it! Its gonna cost me $1400 to fix cause i bent 2 valves and broke timing belt. one day your gonna go outside and its just not gonna start don't keep trying to turn it over like this idiot! you will tear the valves to pieces.. take it from me. Stop driving and get it fixed!

@bbishoppcm that was fucking hilarious ....lol

[geicoman5]

dont give up on it. i have the exact same car. with a timing belt that is getting old. any signs to look for when it is about to blow or something

I agree. I am doing a 2.0 that stripped a belt.The guy cranked it for an hour.

Before attempting the repair, I removed the plugs, filled cylinders w/air.Turn cam to close the valves & they all held 100 psi. So no bent valves.

This one probably slipped from a lose tension adjustment.

You can get a knocking sound from an ignition combustion on an intake stroke because of a jumped belt or chain slamming back a valve that was in the wrong position @ firing time.

Oh man.... that hurts. Sorry dude.

@bbishoppcm Hey Dumbass! Maybe he bought the car used and it probably hads a previouds owner that just didnt care...u foool!
