I hope that you are not interpreting “sealed transmissions” as a good thing. This will inevitably lead to less maintenance and–several years down the road–more transmission failures.

There are many vehicles out there that use chains; too many to sit here and list. Chains usually last the life of the engine and car.

Timing belt is ok if you can do the job of changing it and associated hardware such as the tensioner and water pump if applicable.

Timing chain

To name a few, I was looking for a new pickup truck Toyota tacoma or tundra. I didn’t buy one. Why? both models use timing belts!

My 1979 Toyota Celica (20R Engine) has dual timing chains. I have 200k miles on the engine, and have had no problems with the chains (this is true for most of the 20r engines). I’m told that Toyota moved to a single timing chain on the 22R engine, and those chains do not last as long.

The 20R motors were produced from 1975 to 1980, and the 22R motors from 1981 through 1995. My 94 p/u has a 22RE. I can’t comment much on any issues with the 20R, but I have owned several 22R and 22RE engines. When the chains on these engines stretched out, they would wear two grooves into the timing chain cover and directly into one of the coolant passages behind the waterpump. If left alone, of course disaster occurs. In my experience and talking with several 22R owners, this occurs around 150 kmi… some were sooner or later, and for some it never happened.

Timing belts are generally quieter than chains, but they don’t last quite as long and they usually fail suddenly and without warring, where chains give you more time and usually let you know when they are close to failing.

Can a belt make all the bends required for DOHC and then throw on variable valve lift and duration? Have you seen what GM is doing with its “V” engines that have the cam in the normal place in regards to variable valve timing? the device looks like an AC clutch.

However, it is not true that, “timing chains never need replaced (sic)”. While timing chains are very durable components, it is sometimes necessary to change a timing chain after…maybe 150k–200k miles or so. Many will go for the entire life of the engine, but if someone is in the habit of doing a lot of full-throttle acceleration runs, he will wind up stretching the chain. If someone uses extended oil change intervals, it is possible for sludge build-up to compromise the chain’s lubrication, thus leading to an early demise.

So, timing belts need TO BE replaced as a part of regular maintenance, and timing chains may need TO BE replaced on an as-needed basis, albeit much less often that timing belts need TO BE replaced.

2021927 — Wheel bearings can last up to 100.000 miles. In most cases, however, drivers have to replace them well before reaching that distance threshold.

Subaru’s six-cylinder engines use timing chains, rather than timing belts. That is one reason why I opt for their sixes, the other reason being the absence of head gasket issues on the sixes.

Chain belt vs timing beltcost

I’ll condense the difference between the two. Timing belts, when they fail, tend to result in very expensive catastrophic failure. Most, not all, of the engines are interference engines and bend the valves when they fail.

Timing chains, OTOH, will stretch as they wear. This will typically show some symptom before jumping time. You can also measure the stretch if you can see both the crank pulley and the cam. It’s read/measured in degrees of rotation at the crank.

Another issue was that the timing chain guides were made out of hard nylon. Occasionally the driver-side guide breaks causing a jump in time or in extreme cases bent valves…ask me how I know! Kits are available now with new timing chain covers and steel-backed driver-side guides.

When it comes to getting your timing belt replaced, most car owners often shy away and try to postpone the task because it’s on the expensive end in terms of repair and maintenance. Avoiding timing belt replacement can be a huge mistake, however, as failure has the potential to cause serious damage to your vehicle’s engine. A broken timing belt can render your vehicle inoperable, or even worse, bend your valves and pistons causing major damage to your engine. If you’re uncertain about the specific details of timing belt functions, how to know if there’s an issue, and how timing belt replacement works, we’ve compiled all of the answers to your questions below!

Replacing a timing belt can often be a challenging and labor-intensive job for most car engines. Additionally, a break likely also means that additional parts like the tensioner, water pump, or idler arm might also need to be replaced. To ensure other parts won’t also need replacing, preventative maintenance and getting regular checks on your vehicle are key. Replacing a timing belt on its own is manageable, but if the break has caused other parts to be damaged then the costs can really add up. Unfortunately, timing belts can’t be regularly inspected by the average vehicle owner as most belts are covered and hidden behind other engine parts which obstruct the view. The best way to maintain your car’s belt is through regular and professional maintenance.

The damage a broken timing belt can cause is highly dependent on the type of engine your vehicle has. If your engine is an interference one, one of the functions of the timing belt is that it will keep the valves and pistons from smashing into each other. In the case of a snapped belt, damage can be caused through bending the valves, disrupting the cylinder head or camshaft, or damage might also be caused to the piston or cylinder wall.

Chain belt vs timing beltpros and cons

I wouldn’t worry about belts vs. chains. If you do the recommended maintenance, there’s nothing to worry about. I have over a quarter-million miles on my engine which uses a timing belt. The belt has been changed twice in my ownership of the vehicle.

It is incredibly important to regularly check your vehicle before timing belt issues occur as major malfunctions can result in serious engine damage. The timing of your vehicle’s belt replacement is highly dependent on the specific make and model, however, some generally recommended replacement timelines are after 60,000 to 100,000 miles. Make sure to check your vehicle manual to read up on the exact specifications for your belt’s replacement, and make sure you’re taking your car in for regular service so your timing belt can get checked.

Unfortunately, there aren’t many sure-fire signals that your timing belt needs to be replaced. Normally if there is a serious issue, it will be less of a gradual decline and more of a sudden occurrence. When your belt becomes worn down, there is more of a chance that it will slip completely which will cause misfires. If your timing belt fails, your engine will likely stop immediately or have a significant reduction in power. Alternatively, if your vehicle has a chain rather than a belt, you might hear a significant amount of noise if it becomes loose, and even a loud crack if it breaks. To prevent belt slippage, make sure you’re replacing the part as per the recommended guidelines of your vehicle manual.

Air and gas are let in and out of your engine through valves operated by a camshaft. The crankshaft in your vehicle is what moves the pistons up and down. For your car to function correctly, these systems have to be synchronized exactly or else damage might be caused to the valves, pistons, or engine. The timing belt is there to make sure that the two systems remain synchronized and turning at the correct pace.

Lubrication is critical to a long chain life …and not at all with a timing belt. Each has their technical advantages and shortcomings.

I had a 1990 Toyota Pick-up with the 22R. I changed the timing chain at 250K miles, but only because I was doing a head gasket replacement. The chain still hadn’t reached it’s stretch limit, but was fairly close.

some dont have both chain and belt. Use gear driven!! For instance Dodge Ram truck with Cummins engine use gear driven no belt or chain. Also I believe older Jeep Wrangler with 4cyl engine use gear driven.

Even engine design has a lot to do with timing chain life. Pontiac’s 4-cylinder engine, as used on the early Tempest models, typically needed to have its timing chain replaced every 40k or so. Luckily, just like other timing chains, the rattling noise as it reverberated against the inside of the chain cover was the tip-off that the chain needed to be replaced again.

Can anyone name some cars that have engine timing chains? I understand that timing chains never need replaced but timing belts need replaced as part of regular upkeep but the job is very expensive.

Timing belt vs timing chaincost

If your engine is a non-interference type, then pistons or valves won’t crash into one another if the timing belt breaks because the two aren’t close enough together. Because of this, it’s unlikely there will be extensive damage to the engine, however, you will definitely need to have your vehicle towed into a shop for maintenance and repair services.

But if you ARE worried, I’d look at buying a vehicle that doesn’t have an interference engine, regardless of whether the valvetrain is driven by a belt or chain.

Most of the new Hyundai (and Kia) engine designs are chains. And they are starting to use sealed auto tranmissions, too. Less maintenance all-around

The chains that do fail generally fail due to the poor maintenance habits of the car owners. Poor maintenance habits means extended or irregular oil changes, chronically running the oil level down low, etc. Chains do not like dirty engine oil.

In Pre 1970s, vehicles were built with timing chains, however, companies began to use belts instead as a means to reduce car weight and enhance fuel efficiency. In recent decades some companies have begun to switch back to chains given they have longer durability as long as regular maintenance is scheduled. A timing chain is a relatively maintenance-free part and will rarely need to be replaced, and the maintenance process for a chain, as opposed to a belt, is substantially different. Make sure you read up in your vehicle’s manual to ensure you know which part your car has so you can make sure you’re scheduling the proper amount of service.
