Why did my Honda CRV timing chain jump?
My 2002 CR-V jumped timing due to a faulty tensioner. I was told by a honda tech that the tensioners go every 150,000kms. I don’t believe there was any chain slap. There might be a bent valve, but one thing at a time. I will replace the tensioner, retime the engine, crank it over by hand and see if I have anything hitting.
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.
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.
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.

Are there any problems with the timing chain on a Honda Accord?
I have had multiple problems with the timing chain on the 204 Honda Accord 2.4L 4 cylinder. Mine jumped time at just under 100k miles and was replaced by the dealer at no cost. My daughter has the exact car and hers went at 135,000 miles and the engine died while running.
Why is the crank on my Honda CRV not working?
Problem is crank and cam positions don’t match due to stretched chain. Vehicle has always been serviced at dealer using recommended fluids. 66 people found this helpful. We also got an intermittent check engine light and a dealer diagnosis of P0341, Cam & Crank in incorrect phase. This is on our ’04 Honda CR-V, at 124,000 miles.
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.
How often should the timing chain be replaced?
The timing chain normally needs to be replaced between 40,000 and 100,000 miles unless there is a problem. Issues with the chain are pretty common in high mileage vehicles, so if you are driving an older vehicle, or one with a lot of miles, it is best to be on the lookout for symptoms of the timing chain going bad or failing.
Which Hondas have timing chains?
All the V6 Honda engines in regular production have timing belts (J30, J32 , J35). They switched to chains when the “K” series engine came out (4cyl) and the S2000 has always had a chain (F22).

Can a Honda engine have a stretched timing chain?
Honda engines where the oil level has been allowed to get low repeatedly, have been known to suffer from stretched timing chains. That said, as long as you have monitored and maintained your oil level and don’t get any CEL codes from the crankshaft and camshaft being out of sync, there is no action required.
What to do if you have a jumped timing chain?
Place the vehicle in park with the emergency brake set. Start the engine but be sure the battery has a full charge and is operating at peak performance. Note the speed at which the engine tries to start, comparing it with a normal start condition. An engine with a jumped timing chain will show signs of very sluggish and slow starting.
What is the timing chain removal procedure on 2004 Honda?
Drain the engine oil. Align the timing marks at TDC No.1. Remove or disconnect the following: Negative battery cable Front splash shield Drive belt Cylinder head cover Crankshaft pulley CKP sensor VTC oil control connector VTC oil control solenoid valve Support the engine with a block of wood and jack.
