How long is the timing chain supposed to last?
According to GM, the timing chain is supposed to last for the “life of the engine”. However despite this, I realize that at 230,000 miles, the chain could very well be worn out and need replacement. This question is a followup to this answer.
Can a bad timing chain cause engine damage?
Most, if not all, of these problems will illuminate the Check Engine light. It is also possible for the timing chain to break – although this is not common – with excessive wear or a weak tensioner. That would result in major engine damage.
Which is a disadvantage of a timing belt?
The main disadvantage of a timing belt (as opposed to a chain) is that they deteriorate quickly. Because of this, there’s a higher risk of damage being caused to the engine unexpectedly. In recent years, manufacturers have started to return to using timing chains again. What Will Happen if the Timing Chain Goes?
Why does my timing chain make a rattling noise?
Excess slack in the timing chain can cause a rattling sound or even a clanking sound if the slack is severe enough to cause the chain to contact the timing chain cover. If the engine is equipped with a hydraulic timing chain tensioner, the noise may disappear or lessen as the engine oil warms up and the tensioner removes some of the slack.
Where does the timing chain attach to the engine?
The timing chain or belt attaches to the camshaft, in the top half of your engine, and the crankshaft in the bottom half, ensuring that they turn at the correct speed and time so that your engine runs smoothly.
When does a timing chain start to wear out?
One of the most important components when it comes to regulating the timing of your engine is the timing chain. While timing chains can last for a long time, they do eventually wear out. However, before they break, they usually loosen.
Can a bad timing chain cause an engine to fail?
3. Engine won’t start or fails. A broken timing chain will cause an engine to not start or fail while driving. If the belt is already broken, the engine won’t have enough compression to start. If it breaks or jumps while driving, the pistons will be damaged from contact with the valves.
Which is better roller or stock timing chain?
Some roller timing chain sets are manufactured with larger than stock pins. These are typically found in standard roller chains. This design yields a stronger, more durable chain, but adds more friction than a true roller. Roller timing sets with iron cam gears have wear issues on iron engine blocks.
