Can you drive with a stretched timing chain?
It’s probably not immediately “dangerous” to drive with an elongated chain, but if it gets elongated enough, it will lose tension, start to “slap”, and may break the plastic cam chain guides or jump a tooth on one of the sprockets, which may cause catastrophic engine damage.
Do Honda timing chains stretch?
To be precise, the chains do not stretch, they wear. The link plates and link pins wear where the pins go through the plates. Slight wear on every piece adds up to a longer chain.
What happens to the timing chain on a Honda CRV ex?
I have a 2006 CRV EX and I had to replace the timing chain and tensioner. What happens is that oxidized oil builds up in a critical oil orifice in the tensioner and begins to close it off. The chain is lubricated by pressurized oil coming from this orifice.
What happens when the timing chain is stretched?
When the timing chain is stretched, it makes the engine perform poorly and so the engine emissions are increased. This triggers the engine light to come on. A qualified mechanic will be able to use special software to detect a stored diagnostic trouble code.
Why does my Honda CRV engine not start?
Engine Won’t Start– If your CR-V’s timing chain or belt has fallen off completely, broken, or has jumped a few teeth, it is entirely possible that the engine won’t even start. You might hear it slapping around as the engine cranks over.
When did Honda replace timing chain and tensioner?
This is especially surprising as that dealer had just replaced timing chain and tensioner 2 years ago, under an unspecified “service bulletin”, as no-cost warranty repair (also they were unaware they had done this until I checked my invoice file and told them). As a former mech engineer, I cannot buy the “stretched chain” hypothesis.

Can a loose timing chain cause engine overheating?
Engine overheating: Although rare, if the water pump is driven off the timing chain, a loose timing chain may result in engine overheating. 5. Engine failure: If the timing chain breaks or jumps time — meaning it starts skipping teeth on a gear — the valves may contact the pistons.
