Timing chains usually last the life of the engine, it's the tensioners that go bad around 100k. Once the tensioners go bad, you will usually hear a swishing sound from the left side of the valve cover. The timing can be done with a light, download the FSM or search to get a good idea how to do it. Stick with NGK's, they seem to work best with our cars. Do you have a problem with the car not running smoothly? At 68k, your engine is still a baby so you shouldn't have many problems to worry about besides the oil and the occasional tune-up.MASIAH said:My sentra is at 68,000 miles. I was just wondering, how long do they usually go without being replaced. Also, can my timing bu adjusted by the gun or by computer. It feels like it needs adjusting. I also have tekwire wire set and NGK plugs. Do you guys think I should put NGK wires instead and my car would run smoother. Thankx in advance for your help!
