How does a bad VTC cause an engine failure?

How does a bad VTC cause an engine failure?

The bad VTC causes a drag on the timing chain every time it grinds at start-up. Over time that small drag stresses the timing chain TENSIONER, until it eventually fails. With the timing chain tensioner no longer keeping the chain at constant tension a skipped or broken chain is just a question of time.

What happens if you have a bad VVT solenoid?

A faulty VVT solenoid can cause several problems. The most common include: Your car’s primary computer, which is often referred to as the powertrain control module (PCM), monitors the operation of the VVT solenoid (s). If the PCM detects a problem, it will turn on the check engine light.

What’s the problem with my Honda VTC acutator?

Hi Leviathan, i had the very same problem here – 3 time to service, the VTC twice changed, still rattle noise at cold startup after 10 days from last service stay. They even changed the oil assuming I added a different oil type than the service manual says. I can see that your post is from 2 years ago.

Why is my VTC actuator making a noise?

With the timing chain tensioner no longer keeping the chain at constant tension a skipped or broken chain is just a question of time. This is mechanical fact, whether the interwebs have beaten it to death or not. If your VTC actuator is making noise, get it repaired period.

What happens if you dont replace the VTC?

Here is the kicker,The vtc wont fail bc of the noise but If you dont replace the vtc it puts stress on the chain every startup untill it stretches the chain far enough to jump a few teeth and kaboom !

What happens if the solenoid on a VVT fails?

If the VVT solenoid fails or is blocked, the lack of proper lubrication can cause the timing chain and gear to prematurely wear or break entirely. There are several other problems that may occur when a VVT solenoid is wearing out or has broken that may extend to complete engine failure.
