How old was the timing chain when it broke?
Our timing chain broke at JUST under 50,000km, 2 years old. Initially, the engine was making a strange noise on startup that would go away and sometimes return on acceleration. No warning lights came on. Within a week, the timing chain broke and the motor blew apart.
Why does my engine rattle on a cold start?
Hearing metal on metal during cold starts is never too good though. 90% of engine wear happens on cold starts. One of the most important parts of an oil filter is the anti-drainback valve that keeps oil in the filter.
Why is my timing chain tensioner not working?
The dealership confirmed today that there are metal fragments in the oil filter and in the oil.

Why does my Nissan SL make a rattling noise when I start it?
One is that the VTC gear on the intake cam is making the noise and the other is that the cam chain tensioner is slow in filling with oil (i.e. hydraulic pressure) and it is causing the noise. Sometimes it rattles when we first start it and other times it does not. Once you start the engine, then turn it off it, then restart it, it nevers rattles.

When do you know to change the timing chain?
A timing chain runs inside the engine, as it needs to be lubricated by the engine oil. A timing belt typically needs to be replaced between 40,000 and 100,000 miles depending on the vehicle and it’s a few hundred dollar repair. A timing chain doesn’t need to be replaced unless there is a problem with it.
Why does my car not run on the timing chain?
The intake and exhaust valves open and close in respect to the rotation of the crankshaft, which controls the strokes of the piston for firing. If the two become misaligned or the connection breaks as the result of a bad timing chain, the engine fails to run properly or won’t run at all.
What are the bright links on a timing chain?
Locate marks or “bright” links in your timing chain. These links are brighter than the other links and are used to align your engine. Set your engine to top dead center. To get your engine to top dead center, line the bright links on the timing chain up with the marks on your camshaft and crankshaft gears.
