Ticking while driving with multiple codes?

Hi,

The codes are all over the place. However, there are multiple codes related to the camshaft position sensors. I'm questioning if there is an issue with the timing. It isn't likely that all of them would fail at the same time.

Do me a favor. Record the noise you are hearing and upload it for me to hear. It may help point me in a specific direction.

Let me know.

Hi,

I certainly hear it. Not being there makes it difficult to pinpoint, but it sounds like it could be a cam actuator, or something related to the camshaft. If you get right near the timing chain cover, could the noise be coming from in there?

Listening to it, to me it doesn't sound like a rod knock (bottom end). It sounds like a chain issue, chain tensioner, or even a guide. Please understand that I'm listening to it via a computer, so anything is possible. However, that is what it sounds like to me. Plus, you have cam sensor codes for each one of them.

Let me know your thoughts. Also, let me know if you are comfortable removing the valve covers and the timing chain (if needed).

Take care,

Joe

Hi,

Make sure the chain is tight and inspect the guides to confirm there is nothing damaged or cracked. Also, check for any lifters that are loose.

Take care,

Hi,

Is the one timing chain a lot looser than the other? It's hard to see your hand on the first one you check. Is that the same side that you are seeing oil from the exhaust side?

Also, take a look at the guides. Is anything damaged? If not, we need to confirm the timing is correct. I attached a pic below showing the timing mark locations.

Let me know.

Hi,

Based on how it was running, I don't think there is internal damage, but anything is possible.

If you had a bent valve, for sure there would be a cylinder misfire. You would have felt it.

As far as testing, you have two things to try. First, a compression test will certainly tell you if there is a damaged valve because the compression will be much lower in the affected cylinder.

Here is a link that explains how it's done:

You will need a compression gauge to test. If you don't have one, most parts stores will lend one to you.

On the other hand, if you can get a borescope, you can check down inside of the cylinders for evidence of damage.

Let me know what I can do to help.
