SOURCE: Timing Belt broke while driving my 96 Toyota Rav4,

Zero tolerance means the valves may have hit the piston when the timing belt broke. I would suggest doing a cylinder leakage test to see if the valves are bent or not. If the valves are not bent then you can replace the belt and everything will be ok. If there are bent valves then the cylinder heads will need to be removed and repaired.

SOURCE: Valve job for 2000 VW Jetta GL w/105,000 miles

is he sure it isn't the rings are worn also?  If so don't waste money on a valve job, when you really need a rebuilt motor.  Had you changed the oil more you wouldn't need this repair at this time.  Good uck as his price is decent.  Ask him the price for a long block?

SOURCE: Timing Belt Problem-6 cylinder Saturn wont' start

If your timing belt broke, then it is possible that the valves in your engine got bent, which won't allow the cylinders to pressurize the fuel/air mixture, and it will let all of the mix to flow freely into the intake/exhaust manifold. This can be checked with a pressure tester that is threaded into the spark plug opening. A mechanic should have one, or you can probably find one at an auto parts store.

SOURCE: 1994 1.9 the timing belt broke.did it bend the valves.

For what it's worth, my info tells me it's a non-interference engine, so your o.k. but I will double check that & get back to you.

SOURCE: 03 jetta tdi timing belt broke

The number of miles is not relevant, because in 7 years of driving, obviously it was mostly highway miles and caused little wear.

It only takes about an hour to try just changing the belt. You need to buy a belt anyway. So it is always worth the attempt.
Most VW's have small depressions in the pistons for the valves, to prevent anything serious.

But no, I do not believe the TDI even is an interference fit.
Only the DOHC GTI engine was even close. I do not believe the TDI had a dual cam version, nor was any Jetta dual cam. And it is only with dual cam that the valves hit, because they are on such a hemisherical angle.

What are the chance that I will not need a value job after timing belt broke


A "valve job" typically means resurfacing the valve seats. It is unlikely you would need that after the timing belt broke unless you needed it before the timing belt broke - they aren't related wear items. Depending on the engine (if it is an "interference" engine) you may need new valves or a new top end of the engine because the valves may collide with the pistons when the timing belt breaks, causing a lot of damage. If your engine is not of the "interference" design type, then you probably only need a new timing belt; many shops also recommend replacing the water pump too because its failure can often damage even a new timing belt and there usually is no (or very little) additional labor cost involved. Other maintenance might also be recommended at the same time (like replacing spark plugs), but that too depends on your specific engine.

Timing belt went


If the timing belt broke while the engine was running you are up for lots of dollars. You will have bent valve stems and that means head off and new valves. Best leave this job to experienced mechanics

My timing belt came off on my 2003 chrysler seibring can i fix it myself


Well, a lot depends on your ability to do mechanical things. It also depends on whether you have the proper equipment or not. A timing belt on a Sebring is one of the toughest timing belts out there. It is no walk in the park for a seasoned technician. If the belt is broken, the job just got about 100 times harder to do...

ALL of the engines used in Sebrings in 2004 are "interference engines" meaning that if the timing belt broke while the engine was cranking over or running, there is most likely engine damage resulting from the pistons hitting the valves. The camshafts should be removed and a cylinder leakage test performed before replacing the timing belt. This test will identify any valves that may be bent. The cylinder head (or heads) will have to be removed to repair any of this type of damage. Then again, you might get lucky. The test will tell. I wouldn't even attempt to put a timing belt on one of those engines without doing the leak test FIRST if the belt is broken.

How locate & replace timing belt


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,,

My timing belt broke and I have purchased a new one; however, I need to know how to set the correct timing for a 2001 Volvo S60 witha 2.4L engine?


you need a service manual, if you don't have one i fear that you maybe in over your head-either timing belts or chians there are always timing marks which indicate cylinder id and tdc, basically top dead center of cylinder #1 matched to camshaft position of intake and exhaust valves inclosed position (cam lobes off valves and valve springs relaxed to full height-not compressed as that indicates valves are still open or in overlap-you must know you four strokes and consider which stroke will be required) anyways if your belt broke you may have larger problems than lacking a service manual as most engines today are interferance which means that it the valve timing is incorrect you could be tagging valves against the pistons, and if your belt broke you may have already done so-check your valves as they maybe bent and in this case you require a head job as well.

Timing belt broke


I've heard that honda engines are made so that if your timing belt does brake theres enough room for them not to hit the valve cover, but hey i could be wrong only way to find out is to take off the valve cover and inspect
