![]() If you’re driving an older car or one with a lot of miles on it, keep an eye out for signs that the timing chain is failing. Chain problems are frequent in automobiles with increasing mileage. Unless there is a specific fault, the timing chain should be replaced between 80,000 and 120,000 miles. For optimal power and overall engine performance, as well as fuel economy, proper synchronisation between valve timing and cylinder strokes is required. This component resembles a bicycle chain and generates a louder noise than a timing belt. It serves as a link between the upper (cylinder head and valves) and bottom parts of the engine (pistons and crankcase). This allows the engine’s inlet and outflow valves to open and close at precisely predetermined intervals during each round of the engine. I think it's disgusting due to the amount that have been recalled back.The timing chain is a component of the car engine that synchronises the rotation of the crankshaft and camshaft in the engine’s lower and higher portions. I now have to pay £1000 to get it fixed by a garage. I have a disability where I'm in chronic pain 24/7 and stress makes my pain intensify. I stated it didn't need servicing every year due to low mileage. He also stated if it hadn't got full service history they wouldn't look at it either! It has 5yrs out of 9 yrs I told him. ![]() He stated there was nothing he could do from nissan. When I stated that they should last at least 100.000 miles or a lifetime of the car. He basically patronised me thinking I didn't know anything about timing chains. ![]() Customer service were lovely, thought I had a case for a repair on my faulty timing chain! Then when I spoke to a guy named Benjamin from head office. My 1.6 turbo sport nissan juke has done 38.000 miles. It MUST be replaced when it shows early failure symptoms to protect the engine, especially on interference engines. If the chain breaks this design usually ends up damaging the block and pistons, basically ruining the engine beyond repair. In general, most timing chain engines are interference designs. However, most people do not have the Nismo version. Usual rules apply for Nissan speciality quality, except the quality of the chassis. If you hear about the VR38DETT, this is a Nismo engine. I f the engine has been replaced, there is no way to be sure without just getting it done. However, the VIN will give you a definitive answer if you’re in the US by checking it on the NHTSA website. The 2011-13 MR16DDT Juke has known timing chain issues, so if you want to avoid *any* issues, get it changed at your expense - cheaper to change the chain then the entire engine. If Nissan puts out a TSB, it usually means they use interference engines and they don't want to swap entire engines for free due to negligence. Check the engine code to be sure, but Nissan is fully onboard the interference train unless this is the rare exception. The other thing with Nissan is they almost always use interference engines - which are more powerful, but are prone to head and block damage if the chain/belt breaks, so you need to check the engine with a borescope camera for piston, block and lifter damage if it breaks. The issue is Renault is not known for quality. However, on these Renault Nissans (1999-present), even proper maintenance doesn’t help most of the time because these are not as good as the 90’s Nissan products and specialty cars like the R35 and 350/70Z. That will vary if ANY of the maintenance was delayed or skipped. They usually do last the lifetime of the engine properly maintained (or at the minimum, 2-300k miles provided it is a quality chain, like in a Toyota) but with poor maintenance they usually start to wear out at the ~100k mile point. Timing chains are supposed to last the lifetime of the engine, but that’s never the case most of the time as it depends on the quality of the chain and the maintenance regimen of the owner.
