Q: "If the timing belt breaks in a 1991 pathfinder does it always bend a valve?" Nissan 3.0 V6 OHC is an interference engine. It will bend at least one valve. Probably one or two on each head. If doing the work yourself you might come out OK. If not, a new engine or a new car might be cheaper. I found a D21 SE P/U with that engine and a snapped belt. 4 valves were bent. I did the work myself and plus a bunch of other new parts and ran about $500. I would expect to pay at least $1500 for someone else to do the work. -- scott pleasurizer.com i did the work myself but had a machine shop do the re-valving , i bent every intake valve and cracked a couple seats and still cost me around $900. some engine rebuilding shops or automotive machine shops have exchange heads for about $300 to $350 each.

Can a timing belt hit a valve on 97 dodge stratus?

The timing belt itself can not hit the valve unless you put it inside the intake manifold. If the belt breaks on a 2.0L it will almost always bend valves. The 2.4L and 2.5L very seldom bend valves.

Does it mess the motor up when timing chain breaks on a Saturn SC1?

Yes, if the timing chain breaks a valve will hit a piston, causing significant internal damage. The good news is, the timing chain seldom breaks. The bad news is, if YOURS was one of the few that did break, the engine is toast.

What causes the valve to contact the top of the pistons?

Timing belt breaks or chain jumped. one thing that will cause this problem is over reving the engine. To the poster who said over revving the engine; please explain. I wonder how race cars can turn 12,000 - 16,000 RPM's and not sink a valve if revving has anything to do with it. May be the timing belt breaks? ANOTHER ANSWEREither the timing chain or timing belt has "slipped" (most common) or the valve has been sticking or the engine has been operated at an excessive RPM resulting in valve "float". Valve float depends on the mass of the valve assembly and the strength of the return spring. Elaborate valve assemblies have been established for the purpose of preventing valve float.

What is variale valve timing?

variable valve timing is where the engine changes valve timing based on the driving situation much like ignition timing is changed to meet the needs of the engine in specific situations. in most cars valve timing is static and determined by the timing gear on the camshaft

If the timing belt broke in a 2000 Mazda Protege 1.8 will the car be damaged?

A 2000 Mazda Protege with 1.8 DOHC engine appears to be a "free-running" engine, meaning there is no valve/piston interference in case the timing belt broke. There is enough clearance between the valve and piston, even if the cam stops (i.e. the timing belt breaks) with the valve fully open. Therefore, the car will not be damaged if the timing belt broke.


Is a Mazda Protege engine noninterfering?

Depends on the year. The 2.0 DOHC in a 2001-2003 is said to be a valve interference engine, meaning the valves can become struck by the piston and bent if the timing belt breaks or another event that significantly alters the valve timing occurs.


What is a freewheeling engine?

In a freewheeling engine, the piston tops and the valve bottoms do not share the same mechanical space, even if the timing belt or chain breaks.


Do you need a new engine if the timing chain breaks on your 1994 Ford Courier?

Damage is only done if the motor is an "interference" design. ie the valves and the pistons overlap in the same place, only kept from colliding by the timing chain. When the timing chain breaks on a interference design, valves and pistons smash together. If it's not an interference design, the pistons and valve won't come into contact if the timing chain breaks, so odds are no internal damage done.
