As per the Consumer Guide, the engine 2.5 and 3.0l engines were biult with the timing marks for the cam shafts were in the wrong place and if repalcement timing chains are installed using the marks, engine damage will result.

take to the dealeer, there is a reacll on this, they will repace the gears and chain.

Not to worry. if timing belt broke your engine is fine. it is an overhead cam engine. although there is a good chance depending on your motor size. that one of the composite sprockets the belt runs on broke also. it is common.

99 trooper 3.5 v6 , believe balancer pulley sheared the key.pulley is wobbling and motor knocking like rod knock.is this a zero tolerance engine and are they known for this problem.sounds like motor is out...


IT is a zero tolerance engine which means that if you break a timing belt there will be valve damage. Check the harmonic balancer and if there is a rubber insert between the pulley and the crank shaft hub then replace the harmonic balancer as this rubber has failed and the pulley will fall off. If the key has sheared as you suspect there would be no engine noise as the engine would not be running. Fix the balancer first then check for the noise as it may be just the balancer

Have a 1997 dodge strautes timing belt broke we changed it but it will not start any solutions?


be careful as that motor is a zero tolerance valve clearance. did you time the oil pump properly? also the internal balancer timed properly, You didnt state if this is a single overhead cam 24 valve maybe repost with motor specs as i just did this same job two days ago and it was pretty easy with no problems as long as you aligned all timing marks properly when tightening the tensioner pulley, and also providing the valves did not get damaged

Timming belt / jump time want to repace belt


honda DOHC and SOHC motors have "zero tolerance" motors, this means if they "jump timing" they need to be inspected for head/valve damage, have this done before spending money on replacing the timing belt

If a timing belt break's on a 1990 honda accord does it bend the valve's


I'm not a Honda expert, but when my Ford Escort belt broke the motor kept trying to run and yes the motor eventually blew. It ran on 3 cylinders, then 2. Hope this helps.

Is the 98 trooper 3.5 engine a zero tolerance engine


All engines, be they gas, diesel, electric or aeronauticle, require a tolerance of certain specification as to allow for lubrication of moving parts. An engine can be considered zero tolerance when it has siezed. Please elaborate for me why this question comes to mind. Thank you, Dana

Timing belt broke at hiway speed Is the motor shot ? 1998 Ford Escort


Maybe not. Not all engine have an interference problem. Many wil be fine after the belt is replaced and the valve train is retimed. Was there a lot of noise? If the engine just stopped without much fanfare you are Ok. Check with your mechanic or dealer to be specific.

Thinking about buying a 2002 Galant but it needs a timing belt its a 4cyl.just need to know if it is a zero tolerance motor. to see if it may have bent valves.thank you!


remode all plugs and turn the motor over by hand
that will tell you if it a zero tol motor
remember to insert 1 plug at a time to see is the piston has compression and make sure if you fine a bad cyl to spin the cam a couple of degres to make sure it is just open valves and not bent or broken valves

if for some reason with plugs all out and motor will not turn then it is a zero tol motor and will likely need a head job with the timing belt

Timing Belt broke while driving my 96 Toyota Rav4, 2 wheel drive. Mechanic said that Rav has a zero tolerance engine and engine will need to be replaced. The timing belt has 55,000 miles on it and we were...


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.

No compression!


this could have happened if the timing belt broke. You are supposed to change the timing belt every 60 to 90 thousand miles.
