Cam Phaser/Engine Failure Reports

[smurfslayer]

The way it works is this. If you have the cam phasers rattling, that means they are not getting oil. It will only last a short time before the rattling / lack of oil destroys them. When that happens, the timing chain stretches / breaks. When that happens, the engine will hat already been hurt.

Squatch, show us some evidence of broken timing chain. not rattling, not stretched, broken.

Why does Ford replace the timing chain when they replace the cam phasers then?

Squatch, that’s not the discussion on the floor. You asserted broken timing chain. I want to see that. Others here, I am sure want to as well.

You’re probably asking why. I’m glad you asked. Because the timing chain isn’t the weak link in this equation. But then, you surely know that.

And I do know why Ford, and other manufacturers replaces the timing chain for a phaser repair, but that’s another topic matter for now. Let’s see those broken timing chains.

I think you answered your own question. The cam phasers fail, then they damage the chains if not repaired quickly. That is the only point really. This is why Ford replaces both when they get a cold start rattle complaint. It's the same work being done on the 15/16 3.5 ecoboost, and even the previous gen ecoboost of 2010-14.
Merry Christmas man - sounds like you need some holiday cheer.

I've seen most, if not all, trucks in for this issue get new timing chains. Cam phaser is cause, timing chain is damage.

Two different trucks in the Houston group caught it early and still got new timing chains.

I had to pay out of pocket for chains and new tensioners. The tensioners were also updated.

What! Why? Out of warranty?

Edit NVM, read other post. Do they think new tensioners will finally solve the problem?

Tech said they would only authorize phasers. He also said that the timing systems, historically speaking, need to be addressed every 100k. The tensioners are updated, they are quite a bit stiffer off the spring with a more robust ratchet system. At 25k in it was ultimately cheaper for me to cough up a few hundred in parts now vs later with labor out of pocket.

Gotta say, I think modern emissions standards, an ever increasing competition for more horsepower and veering away from models like TQM for sixth sigma have made the modern vehicle very unreliable. I’d love to have a simple, if such concept exists, 7.0 NA engine in this thing.

“Six Sigma projects are managed by "black belts" who have gone through formal training and have a proven track record in quality gains. These individuals work full time on Six Sigma in their departments but return to their previous jobs after a few years. TQM is run by the quality control department and professionals who specialize on quality improvements, usually, for their entire career. Six Sigma aims to spread the ownership of quality improvement to the entire organization while those who run TQM are more experienced in the quality field. Six Sigma is often driven by a focus on cutting costs and tends to work best if it has specific financial goals. TQM, however, pursues objectives that are harder to boil down to a single figure, such as customer satisfaction and long-term strategic excellence.”

I had serious engine problems. No timing codes however significant misfire events, flashing CEL and limp mode if I tried to get on it.

And this was specifically linked back to the cam phasers?

For sure. When the tech pulled the valve covers and front timing cover off you could rotate the RH cam shaft back and forth and nothing else in the system was moving. There was probably 20° of rotational play when un-pressurized.

He has done a lot of these and said mine was pretty bad, not the worse.
