![]() In the case of timing gear, it really is better safe than sorry. The last thing you want to do is get a couple of thousand miles into ownership before the belt fails and you’re left with a severely broken engine and a horrendous labour bill. ![]() To stop this ever happening, I would advise getting the timing belt changed immediately on any high-mileage car that you buy, unless there is blatant evidence that it has already been changed recently. The continued reciprocation of the pistons will then send a piston head crashing up into the opened valve, crushing it and therefore producing a potentially fatal bill once you’re towed to the local garage. 1.It may solve the problem such as low transmission efficiency and. This is particularly troublesome in an interference engine, where the pistons share their TDC with the same area that the valve extend to. Timing Belt for Chinese Cars, Find Details about Auto Timing Belt, Fan Belt from. Let’s say your timing belt jumps or even snaps the camshafts will inevitably leave whichever valve was open at the time in its actuated position within the cylinder. Over time, the belt can become slack (or over-tighten), teeth can be worn down or ping off during operation, all to potentially catastrophic effect. And keeping an eye on your car’s mileage in relation to the timing belt is certainly not something that should ever be neglected. Couple that with ever thinner oils due to fuel efficiency requirements, chains just don't last much further than the warranty period in some cars (but definitely not most or all).As an alternative to a belt, timing chains are seen to be a much more durable method of keeping an engine in time, as belts can last as little as 40,000 miles before they begin to wear and need replacing. However, with the more recent "built as cheaply as absolutely possible" mentality there are many examples where the parts used aren't designed to be strong or durable enough in the long run, which means that chains stretch and sprockets wear out way before the vehicle is otherwise useless. The general pros and cons used to be that chains were service-free for what was realistically the expected life of the vehicle and belts were reserved for cheaper cars. Some cars have them built in a way that makes them hard to change due to the location increasing the cost, or some weird shit like the wet belts that are encased in the engine block of some Ford Ecoboost engines (it's a "lifetime" belt, as in, when it snaps, the life ends). ![]() Some cars have awesome timing belts that are easy and convenient to change making sure that if you do the maintenance, the engine will go on for a while (honestly most timing belts if you stick to the replacement schedule). Some have unreliable underbuilt garbage (BMW diesels) that fails prematurely and takes a bunch of other stuff with it making it waaaay more expensive to replace than if it was just a belt, and to top it off, some are at the back of the motor, meaning engine removal to change. Some cars have awesome timing chains that last a long while (honda K series, except for some tensioner problems). They're only as good as they're made to be.
