Timing Belt Broke. 2002 Volkswagen Passat . Time for a new car?
Today my mechanic said that my timing belt broke and most likely 75% chance that the valves are bent. If the valves are bent then it would cost apprx. $100 for each to be fixed. My car has 12 valves? If the valves are bent then it may be feasible to pay for a entire new engine which a used one would cost about $4000. Any advice? Does my mechanics' analysis sound right?

You can have your mechanic pull the valve cover. Loosen the bolts that hold the cam(s) in place and do a compression test. If one or more cylinders is low on compression the motor is junk. If the compression test is fine reinstall the cam and replace the timing belt and you should be good to go.
find the bolts attaching the bracket to the engine (possibley2 or 3) Buy a genuine replacement assy and fit get a new belt as the old one may have suffered damage. Replace where you removed the broken bit and adjust the belt to the correct tension
Your timing belt is behind the pulleys and belt and you will have to remove the plastic cover to get to the timing belt Caution though because if you set the timing belt wrong or if it broke the chances are you will have to remove the head because the neon engine is a interference engine this meaning the pistons with hit the valves. If you are not skilled enough to tackle this job I would take it to a mechanic to do the repair,,
I'm assuming you meant if the timing belt broke would the pistons hit your valves? 2 parts to this, #1 if your belt just broke you should be fine, #2 if your belt skipped time significantly (highly improbable) only then would your internal components have a chance of hitting each other from components trying to open and close at improper times. This could damage both intake/exhaust valves, other valve train components and even damage the head of your pistons.
Its always hard to know if you bent valves or not with out taking it to a garage. Ask yourself these questions. When the belt broke did you continue to try and drive it? Did you try and run the vehicle after the belt broke and how how was vehicle did the temp spike up and stay hot for long?
If you answered no then chances are your probally just fine with a new belt and reset the timing
Replacement of the timing belts is a critical maintenance item on most all VW's. Usually start watching the performance begining at about 70,000 miles. Dealer cost for the service is typically in the $600-750 range. Other parts should also be replaced once the timing belt is exposed. A timing belt failure can result in severe damafge to the engine, and can kill most engines when it occurs. Engine replacement is an expensive repair.
No you could be lucky depends on RPM at time of brakage but chances are the valves are bent a good mechanic can pull the head have it reworked and reinstall it for about $600 or you can buy a chilton
manual disconnect the exaust the intake pull the head have it reworked for about $225 $45.00 new belt $60.00 for a new head gasket cost $330.00 but you have to do it your self. But You May have been lucky a long time ago a friend of mine had a timing belt break on a fiat shop told him $300 this was in 1987 I bought the car from him for $50.00 dollars $15 dollars more than the junkyard would give him I bought a timing belt for $25.00 spent 3hrs installing it, Drove the car for a year and a half till one of the rear strut mounts tore loose still a good deal but I was lucky had valves been bent i would have lost 75 dollars in87 that was 1/2 a weeks pay wish you the best of luck oh by the way most engines bend valves
when the timing belt / chain break
That Can Only Be Determined After Replacing the Timing Belt Or Removing the Head, It has Been MY Experience that About 20% DO Have Valve Damage. This is Aftet MY 30 Years As A Mech/Tech. I Normaly Advise Customer Of the Chances And R&R Timing Belt and as I Say Toyota Is Better than Honda About NOT Tapping Valves when jumping Time.
