Yes the chain on my last 1972 Hillman Avenger made a horrible noise when it was worn out. The engine wouldn't have smashed itself up but changing it anyway wasn't too expensive. My present 1972 Avenger had the chain checked when the engine was rebuilt, didn't need changing. Good for another 46 years or so.

@black guy Technically you are correct, but I was not being a dick, I was trying to express my opinion that if the timing belt is changed on time (by miles or years) then it's not likely to be a concern, and the "warning" is in the owners handbook rather than waiting for a noise. Sorry if I was not clear.

@steve_put_this_here 5 жыл бұрын

Absolutely not true. My parent's 77 Buick (Built with the 403 Olds engine) broke a timing chain with no warning - unless you consider a loud "BANG" a second before it broke "ample warning"! A chain link can snap on an otherwise decent chain. I recall my 79 305 making a hell of a lot of noise; not so much for the chain being worn, but rather the nylon teeth they put on the gears. That didn't break, but you could bet money that the gears and chain were replaced with a good double-roller chain!

@AlexDlugosch 5 жыл бұрын

@@Naturalhit The rubber exterior of the belt may have been fine but the tensile cords in the belt are affected by fatigue over time, and there is no way to inspect these. Just before a catastrophic failure of the belt, the cords begin to break progressively and the belt lengthens slightly as the fibres break and pull through the rubber slightly. But again, there's no way to determine when this is actually happening before the belt completely fails.

Hey Scotty, Back in the day, Ford made their engines (302 in my case) with a timing chain, BUT the timing gear had a thick nylon tooth coating on it. It would disintegrate at about 120k miles. The fragments would fall into the oil pan and get sucked up by the oil pump.Then you'd have to remove the pan AND the pump to clean it all out.

Hi Scotty, I am from Europe and have to say that things said here are only partially true for Europian cars. As it goes, car manufacturers tend to skip out on material quality so we had cars with a lot of timing chain issues. It culminated with VW Golf TSI engine which had a timing chain that I would not fit on a bicycle, let alone on the car. People reported that it overstretched after 25.000 miles only. On the other hand, modern timing belts are not made solely from rubber anymore. Today they are made from glass fibres and aramids (like kevlar), and some manufacturers (like ford) introduced wet timing belt system and they can last for hundreds of thousands of miles.

69 Mercury Cougar V8 had timing chain. However, the crankshaft sprocket was steel but the camshaft sprocket was some sort of composite that wore out. (I bought it used so I don't know if it had been previously replaced with cheap parts). Easy to replace timing chain and sprocket. Replaced timing belt of 74 Mustang II. But it was hard to put the belt on while keeping the sprockets lined up. It seems like it took a dozen tries. I'm glad they are back to gears. But I don't do my own repairs anymore. I'm too busy and modern cars are too cramped under the hood.

@ldnwholesale8552 5 жыл бұрын

All Ford gears of that vintage had nylon faced alloy cam gear. With a link belt chain. Actually quite a big job when they fail as you have to remove the whole front of the engine and drop the front of the pan to get the cover off and back on. And often end up with an oil leak after. Or pull the pan by lifting the engine up as far as it will go, removing the sway bar and pull the pan out by turning the crank so as to wiggle the pan off. though that is the best way as there will be all the dead gear crap in the pan anyway. Days work however with a p/s AC car.

It can happen with chains, too - though more often than not, it's because the chain slips rather than breaks. Had it happen on an old Chevy. The chain didn't stretch all that much; the issue was that GM used a cam sprocket that had its teeth jacketed in nylon to help keep engine noise to a minimum. Over the years, the nylon got brittle and started breaking off, and once enough had worn away or broken, it left enough slop in the timing set that the timing would eventually jump.

The problem I had on the two timing belts that I lost about 20 years ago (one on an interference engine 😢, one on a noninterference engine 😁) was not that the belts "snapped". Both sheared off the teeth on the belt at one location. Examination showed that the teeth on the belt were cracked and degraded. However, having looked at more recent belts replaced after 10 years, the belts seemed to be in much better shape with no signs of cracking. Perhaps the belts have improved? I don't think the engines are running cooler (which would presumably cause the belts to degrade more slowly).

Not only saving money to buy a transmission also during my timing chain when I had the time to do it. Hopefully this is the last night I’ll be riding the NJ Transit for awhile.

Loved my old ('96 and older) Ford 4.9 litres. Or 300 CID inline six for you old goats. Gear to gear, no timing chain. And those engines were built like a tank. Originally designed for industrial applications they got put in pickups as a temporary measure. That turned into long term. Great for us old guys that ran the wheels off service trucks.

I always hated timing belts in principal. The first time I saw one, I thought the engineers were completely insane. I spent a couple of hours trying to wrap my head around why any engineer would choose such a sloppy and poor solution to something that absolutely needed maximum reliability. This is why you should never buy a brand new car. Always buy used, a couple of years after all the bugs have been discovered. Scotty, I worked as a transmission mechanic. Quite often, we had to do rebuilds that required engineering updates to improve lubrication or solve other factory issues. It would be interesting for viewers to know how often brand new cars get these unknown updates that are only addressed after equipment failure, during the repair process.

@CurlyFromTheSwirly 9 ай бұрын

You should buy used card cause they are more affordable. If you can afford a new car, it's best to wait till the end of the year when both delears & makers are offering incentives. By that point plenty of people have already noticed and reported the bugs your talking about.

Great video. My dad owned a 1969 Pontiac Grand Prix that had a 428 Cubic inch engine. At about 30,000 miles, the timing chain "jumped". These engines, from the factory, had a timing chain containing metal sprockets that had nylon (plastic) teeth. It was the premature wear of these nylon teeth that caused the timing chain to "jump". Pontiac told him that this design made the engine run quieter. We all know that making gears containing plastic teeth was probably cheaper to manufacture. Thankfully, there was no other engine damage as a result of the timing chain jumping. The timing chain was replaced with a heavy duty, all steel timing chain and sprockets. The engine did not sound any louder after the replacement. 52 years later, the engine still runs good with the same, all steel timing chain assembly.

Have clicked 345,000km in my 2000 Ford Falcon and it still runs like new with nothing but fluid changes and the odd pulley replacing. Services cost me around $20-30 every 6 months on an engine with such a simple, solid design!

The main reason why timing gears aren't used nowadays has nothing to do with expense or the whining sound they make. Timing gears receive harmonic vibrations from the engine and adjacent parts pick up some of it. This trips the knock sensor in modern cars which makes the ignition timing go wonky.

You really don't hear any noise with the timing gears LOL. My 84 Ranger and Bronco 2 had the 2.8L V6 engine which had timing gears. When they switched to the 2.9L fuel injected V6 in 1986 they dumped the timing gears for a timing chain. Timing gears or a timing chain will be fine, its the built in expensive failures of timing belts that really pisses me off...they couldn't spend an extra quarter to just put a timing chain in rather than a damn belt that will fail and cause major damage in several engines. Engineering/cost cutting at its best, and they'll just rape you when you come in needing that belt changed because...well not only did they cheap out and install a rubber belt they also installed a nice plastic water pump for you as well that needs replaced at the same time.

I had a 6 cylinder Ford in 1966. One timing gear was steel the other was nylon. Eventually at around 100k the nylon gear would start to wear out or "feather". New set of gears cost $40. That was about a third of a week's pay back then for comparison purposes. It had no "whine".
