does it have variable valve timing. no that's y u got a belt. ud bend and break alot more than jus vavles
First off the 4.7L uses a timing chain, not a belt. Second, it could bend valves if the chain breaks.
Yes, it can bend valves when a timing belt breaks.
No because unlike Hondas this machine doesn't has an interference design where the pistons could hit valves when timing belt breaks.
Valves can bend if the timing belt breaks, so it is interference.
Yes!!!
yes if the timing belt breaks the pistons will hit the valves and the motor will have to have a complete overhaul before it will run again
Yes, the valves generally will collide with the pistons. You can imagine the rest. If you where super lucky, there is one spot where all of the valves would be closed. ( unlikely!)
Went the belt breaks the engine still turns for a short time. The belt controls the cam shafts went it breaks the cams stop turning. Some of the valves will be in the open position as the piston comes up it hits the valves and will bend them this is not a good thing to happen. It can do some serious damage to the engine.
It is about 50% possible for the valves to hit the head on a Neon. Sometimes it does, sometimes it doesn't.
A 2000 Honday Odyssey is an interference engine. This means that that if the piston and the valves are not in proper timing (for example when the timing belt breaks) there is a possibility that the pistons will hit the valves and cause damage because they have the potential to occupy the same space at the same time (i.e. INTERFER with each other). On these types of engines since engine damage is very likely in the event of timing belt failure, it is HIGHLY recommended that they be changed at the recommended interval.
The 2000 Mercury Villager uses a timing belt and has a non-interference engine. Which means that if the timing belt were to break that no engine damage would occur from the valves and pistons hitting each other.
I assume you're talking about the 4-cylinder engine, and yes, it is a non-interference engine. The pistons have "cutouts"to prevent the valves hitting them in case the timing belt breaks. This doesn't apply to the V6, of course, since it has a timing chain, rather than a belt.
