Do Honda timing chains need to be replaced?
The timing chain normally needs to be replaced between 80,000 and 120,000 miles unless there is a specific problem. If driving an older vehicle, or one with close to 100,000 miles, it is recommended to look for symptoms of the timing chain going bad or failing.
How do I know if my timing chain needs to be replaced?
When to Change the Timing Chain
- Timing chain noise.
- Engine misfire and poor performance.
- Difficulty in starting the vehicle.
- Illuminated check engine light.
- Engine vibration or shaking when idling.
- Engine won’t start.
Will advance timing cause rich?
No, but it can make it smell ‘acidic’ or sharp with increased NOx. It would not smell rich. If you smell gas, it’s idle mixture, or a small leak, or a hot carb percolating fuel, or your tank venting, etc.
Does timing affect air fuel ratio?
timing can’t have an effect on a/f ratio, but as dave inferred, timing can affect the output of a motor under load.
What is a good air to fuel ratio?
The ideal air-fuel ratio that burns all fuel without excess air is 14.7:1. This is referred to as the “stoichiometric” mixture.
Can adjusting timing reduce heat?
Retarded timing makes for a hotter running engine. The fuel is burned less efficiently requiring more fuel for similar power levels. However this fuel IS burning and creating heat as it exits the engine.
Will car overheat if timing is off?
Some overheating problems aren’t related to the cooling system at all. Late timing alone doesn’t cause an engine to overheat by more than a few degrees, but when coupled with other problems, it can bring the engine temperature to a critical point.
Can timing affect engine temp?
Advancing ignition timing increases engine temperatures. As you increase towards MBT you get more power but temperatures may get so high that you melt a through the combustion temperature + compression increasing temperatures.
Can timing make engine run hot?
A very high degree of timing change might lead to stalling of engine. The piston will be moving upwards and the thrust developed on the piston head due to premature ignition will be converted into heat which overheats the engine. So bad timing can be a cause for engine overheating.
Will too much timing advance cause overheating?
Too much advanced timing can eventually result in overheating but you would probably notice poor performance, backfires, or pinging before overheating begins – assuming you don’t keep driving under these conditions.
Can timing chain cause car to overheat?
Engine overheating: Although rare, if the water pump is driven off the timing chain, a loose timing chain may result in engine overheating.
Can running too rich cause overheating?
Yes! Running rich will make one overheat. And lowering the temperature of the T-stat won’t make one run cooler. Once the T-stat opens you are gonna get what you get as far as temperature!
Is it better to run an engine lean or rich?
Running lean can give you more power but to lean will blow your engine. Running too rich can also hurt your motor. Think of it when you are mixing gas for your weed wacker. It is always safe to add a little more oil than not enough to the mixture.
