One symptom of a bad time chaining is a shaking when the engine is in idle. The valves in the engine may also clatter or knock and the car could also backfire.
Noise coming from the area of the chain and in severe cases it will jump a tooth and the engine will run very badly with no power.
When the timing chain is bad on a 2002 Cavalier, the engine could have several symptoms. The engine could run rough, be hard to start, or not run at all.
A loose timing chain should be replaced.
Timing belt or chain may be bad.
Car will run rough ,backfire and you may be able to here it rattling.
Bad timing/valves/rockers/timing chain
Do you mean a bad timing chain ? The 2.3 liter four cylinder engine in a 2005 Ford Escape has a timing CHAIN instead of a timing belt
The symptoms of a 4.3 liter V-6 engine timing chain problem is an engine that runs very rough. The engine will shake violently.
With a broken chain the engine won't run at all.
Incorrect Timing Can Cause Backfire.
The timing chain should last the lifetime of the engine. I would like to know the symptoms.
Parts and labor to replace the timing chain on a Nissan Maxima will easily exceed over $1,500.00. If you have to incur the expense, might as well also spend another $500.00 to replace the water pump. [Note: when that timing chain goes, you lose the engine. Engine-replacement is over $3,000.] The timing chain shouldn't really break. "Going-bad" will be where the timing chain is getting loose and the sound of the chain flapping around inside its assembly can actually be heard as you rev the engine. Have a reliable mechanic give you their assessment of what's happening with the timing chain (and the water pump). Might as well get a second mechanic give a second opinion.
