| Corolla 2010 Timing chain? | 36Relevance | 5 years ago | alrontal | Submit Your Question HERE | |
| Hi Scotty, I was watching you're video 'This Scan Tool Destroyed My Car and I'm Mad as Hell'. Recently bought this 2010 Corolla 1.8L 2ZR-FE, Manual transmission 5 speed, it has 187500Km. It has no codes and mostly runs well though it has some roughness to it running after slowing down at idle. I haven't driven manual in 30 years so am rusty though it does seem to stall too easliy from a start. I've changed the plugs (which i dont think were ever changed and looked worn out but had a nice colour and no deposits), cleaned the throttle body all of which have made it run much smoother. After seeing you're video above I tried the Blue Driver scanner and noticed the timing flipping all over as you had described in the video. I have swapped the coils around on cylinder 1&3, still the same. A few questions: Could it be something else other than chain with the timing flipping as you described? If the chain is actually bad, which i have a sense it is, is the car worthwile fixing? What i mean is if the chain is bad which from my understanding shouldnt' be at that #of Km's means the oil likely wasnt changed frequently. Are there likely to be other damages to the engine making the timing chain just the first of a string of problems? I was in a hurry when i bought the car from a family member who didnt have the car long and didnt do my due diligence of running the scanner before buying. big mistake! live and learn. You've sold me on Toyotas Scotty and I don't blame the car or manufacturing as the first owner never took care of it. | |||||
| Answer to: Car runs worse with camshaft position sensor plugged in | 35Relevance | 1 year ago | Justin Shepherd | Submit Your Question HERE | |
| You can't tell if the timing chain is off by thousandths of an inch or less by observing it visually. If it were "off" enough to notice with your eyes, the engine probably wouldn't run at all. The timing chain doesn’t wear out evenly. Every time you shut the car off and start it back up, the timing chain starts wearing out until the oil pump builds up sufficient pressure. Over thousands of start-up cycles, random chance says that certain links in the chain will wear out more than others, eventually leading to uneven firing. When you don't have the camshaft position sensor installed, the crankshaft position sensor takes over the engine's firing order. The PCM "knows" more or less when to fire the spark plugs because it's been programmed into it. The camshaft position sensor fine tunes the firing cycle so it's more precise. When the timing chain is stretched, the fine tuning effect is lost. | |||||

| That engine (2.4L I4 K24A4) should have a timing chain only. See below: It is located behind the timing cover - you can’t see it without removing the cover first. | |||||
| Answer to: 2015 Mazda 6 Timing Chain replacement or not? | 30Relevance | 5 years ago | theeel | Submit Your Question HERE | |
| I often wonder about when to change the timing chain on any vehicle. I've watched videos where the chain had to be replaced as soon as 40,000 miles. Some people with my car (2002 Mustang GT with 71,000 miles) had to change their chain at 75,000 miles. Surely these chains last a lot longer than this. Who would want the expense of changing a chain every 50,000-100,000 miles? | |||||
| Answer to: 2010 Mazda CX-9 Timing Chain | 30Relevance | 5 years ago | springer2 | Submit Your Question HERE | |
| The timing chain, with proper oil changes, should last for the life of the engine and is not normally replaced without cause. A faulty chain or chain tensioner will normally set a CEL or at least start making noise. Also unlike a belt, it is uncommon for a chain to just break without the above warnings first. If there are no CEL and no unusual noise, just continue the routine engine maintenance, not change it. | |||||

| Why are you replacing the timing chain? With proper oil changes, you shouldn't have to touch the chain. If the chain is worn, the engine often has problems, so it's worth considering why you're changing the chain. | |||||
| 2016 Hyundai Accent Timing chain noise | 35Relevance | 2 years ago | rocky85 | Submit Your Question HERE | |
| ... vehicle meticulously. I am the second owner and the car was in the family before I owned it. I got the car at about 25000 kilometres and vehicle was service regularly before I owned it. The issue is what sounds like a slight timing chain rattle only under light acceleration when driving and it only happens at low RPM's just above 1500rpm and under 2000rpm and it is generally happening when doing speeds of about 20 kph to under 60kph does not happen at speeds above 60 kilometres per hour. it will only happen within that acceleration band and then as s ... | |||||
| Heating issue in Opel Corsa (whether to fix or sell) | 34Relevance | 6 months ago | jaz059 | Submit Your Question HERE | |
| Can you tell me what is wrong with my car and whether it’s worth fixing. It’s a Vauxhall (Opel) corsa D, 2009, 142,000 miles. I have owned it since 2018 where it had 60,000 miles on it. I am based in the UK England. So far I have done the following works to it over the years. - new A/c compressor - new clutch- new alternator -recently new coil pack and spark plugs due to misfiring - new rear silencer as it fell off due to rust - changed rocker cover gasket - new oil pressure switch-changed oxygen and crankshaft sensor Now the heater is only blowing out lukewarm air not hot like it used to. I took it to a mechanic who looked at it for free and he said the following (not sure if it’s accurate). - doesn’t think it’s head gasket as there’s no white smoke from the exhaust, engine is not cranking when I start the car (starts first time). - he felt the two pipes in the engine bay and one was hotter than the other ( so it could be a circulation issue) - he touched the coolant with his hands and said it looks like something is mixing with the coolant. Could be oil or could be something someone who owned the car before me has added into the coolant (sealant of some sort). - said it could be water pump as that circulates the coolant around the engine. timing chain is making a ticking noise and rattling on cold start so advised if changing the water pump might as well change timing chain also. Quoted me £500 for timing chain and water pump with parts and labour or £250/300 for labour only if I buy the parts. - said could try bleeding the cooling system and adding new coolant ( advised to get concentrated antifreeze and not the ready mixed) as concentrated is stronger. - advised to start using 10w 40 engine oil and not 5w 30 as thicker oil is better for older engine and it will stop the timing chain rattling. I don’t know how accurate that is ? - but I have also noted a leak underneath my car by the drivers side allow~ which could be coolant I can send pictures. So I’m not sure where I should start first. Should I get the leaks fixed first and try flushing the cooling system . Before doing timing chain and water pump ? - he also advised me to add white vinegar or radiator flush to the coolant reservoir and leave cap off and rev engine to 2000 rpm for 2 mins. Did that this afternoon myself Overall is there any value in doing any repairs with this high mileage. Cars value is approx £1000-£1500. | |||||
| Do timing chains need to be changed at regular intervals like timing belts need to be? | 30Relevance | 6 years ago | carguy13 | Submit Your Question HERE | |
| Hi everyone, I have a 2004 Toyota Corolla with a timing chain. I know timing chains can stretch over time and it's very expensive to change them because the guides and gears have to be changed also. My Corolla is nearing 200K. Should I be proactive and change the timing chain which is like a $800 job or wait? I've heard you'll get warning signs if a chain is about to break, I've also heard Corollas have non interference engines so all this makes me want to put off doing this. Can Scotty or anyone tell me this? | |||||
| Answer to: when should a timing chain be replaced? | 30Relevance | 5 years ago | OLD GUYS RULE | Submit Your Question HERE | |
| Well, I'm not a professional mechanic but I do have a 2001 Mustang GT with 153K miles and I have no indications of timing chain problems. There are actually two chains on the 4.6 SOHC engine. If the car hasn't been abused and you take reasonably good care of it in the future, you can rest easy on the timing chains. A timing light doesn't work because there are no timing marks. You can't adjust it anyway, the computer controls the timing. | |||||
| Should I replace the timing chain | 29Relevance | 4 years ago | CuriousMarina | Submit Your Question HERE | |
| Hi there Scotty, My name is Marina, I have a 2006 Nissan Altima SE 3.5 6 cylinder automatic. Recently I heard a tapping noise and I was told it was my timing chain quite a penny I come to find out that it's going to cost the car has over 200,000 miles on it should I go ahead and pay to do the timing chain on it or should I just have the engine rebuilt. Thank you for your time in this matter I am a girl that has worked on vehicles of my own but in this case I just don't know what to do... | |||||
| E-CVT and timing chain longevity? | 29Relevance | 3 years ago | Japancarfan | Submit Your Question HERE | |
| Hello, I'm wondering about one thing. ECVT keeps engine rpm at very low level when driving normally, below 2k rpm, let's say it's around 1500 rpm most of the time. How this affects timing chain and general health of the engine? Because if you drive a manual transmission car like that you will basically stretch a timing chain and put a lot of stress on connecting rod and pistons. Is ECVT somehow putting less stress on the engine at low rpm? And engine is safe form chain stretching and connecting rod, pistons problems? Sorry for my English, it's not my first language. | |||||
| Answer to: Chevy equinox 2013, odd sound after drilling pcv manifold, | 34Relevance | 4 years ago | Chuck Tobias | Submit Your Question HERE | |
| As @doc says, the PCV valve has nothing to do with timing, except perhaps a clogged PCV valve could lead to sludge buildup over time which could affect the timing chain and tensioner. Drilling into the manifold? For what purpose? Rattling is typicaly caused by a worn timing chain or loose tensioner, and those vehicles are known for timing chain and other engine problems. Better get it repaired since that's an interference engine and it will self-destruct if the chain lets go. (You didn't say what engine you have but both the 2.4 and 3.6 are interference engines known for timing chain problems.) You've been very lucky to get nearly 200K miles out of that thing. | |||||
| Answer to: 2002 Maxima | 34Relevance | 5 years ago | Kerem | Submit Your Question HERE | |
| Pass That was the first year of the 3.5 V6 and you could look up on youtube where many mechanics talk about how they had issues, specifically timing chain I believe. Maximas are screaming cars they are awesome but nowadays they tend to have problems with their CVT autos, though 02 isn't affected. The French company Renault merged with Nissan in 2001 and Nissans after then had more issues than before. I would want proof of the mileage, have a mechanic check it out, and haggle if you are considering buying it. Owner complaints show high number of engine issues Noisy/rattling timing chain is very common issue with the earlier 3.5 V6 Ratchets And Wrenches on Youtube, "Top 10 Reliable Cars Under 5K - 10 MOST Reliable Cars Less Than $5000" "#5 : Nissan Maxima from 1995 to 2001, these cars come with a 3.0 V6... However, the Maximas from 2002 and 2003 are not on my list because in 2002 the 3.5 engines were used and those used a timing chain which had issues with both the timing chain and timing chain tensioner..." Actually, my father's first car was a 1994 Nissan Maxima. It was decent until it was around 15 years old and then the engine fell apart. The next couple generations showed a huge decrease in quality. All in all I do not think this vehicle is a good buy. With my 3k, I'd look for a Toyota Camry/Avalon with a bit more miles, which would still be a lot more trouble free for a long time. | |||||
