Thanks for having this very helpful site!!
Due to severe burns suffered in a Jet Truck fire last year, I was forced to use a local shop change the timing chains and water pump 3,000 miles ago.
It’s run fine since but now suddenly started misfiring briefly after morning startups.
Check engine light is on and shows active codes P0011 & P0014. Both VVT solenoids were changed with timing chains and guides.
There is also a loud tinny engine rattle after running for a couple of minutes. I also noticed that at operating temperature, both cam phasers show 0 overlap but work fine for several minutes after first starting. This is also when the rattling in the engine starts.
I thought maybe a cam chain guide may have come loose but I would think that would be constant not just after warming up.
The car runs normal going down the road with full power. I’m just leery of running it like this.
Any ideas would be very much appreciated!!
Thank You

I’m sorry you were injured, hopefully your recovery is complete.
the P0011 can indicate cam timing out , a loose timing chain( broken front guide) or clogged up solenoid can also be the culprit

Pretty much the same for the P0014, I have had both and resolved the problem by replacing the timing chain and installing a ZZP front guide in place of the black plastic GM style guide.
I replaced both solenoids

Now before you order anything, remove the valve cover and check for a loose chain and a damaged front guide, remove the solenoids and inspect for clogged oil passages in the mesh

The are some cheapo kits out there that include unneeded parts that do more harm than good. That includes poor quality phaser, solenoid valves, and chain tensioners.
In addition to the inspecions already suggested, with the valve cover off I would look would look down the front chain gallery an try to see if the front guide looks intact. It's notorious for breaking very quickly, especially in an engine that sees high-RPM operation. Also, ask your mechanic if the phasers were changed.
Let me ask some questions. What symptoms led to the timing chain job? How many miles on the engine? Any prior problem or repair history? What do you know about the oil change history? What oil is in it now? Any additives? And finally, a kinda dumb question but just to be sure, have you checked the oil level?

I was told it was a Cloyes kit, but wasn’t able to be there to see it. The kit also supposedly had both phasers and was supposedly changed.
My wife was driving the car and started running hot for no apparent reason. I’d been planning to change the timing chains anyway because of mileage concerns, so I had to have a shop do the work including replacing the water pump. This was at 120,000 and is now at 123,000. I’ve had the car since around 24,000 miles and other than regular normal maintenance, I’ve had to change several cam phasers.
Oil changes have been regular between 3,000 to sometimes close to 4,000 miles.
Ive always ran 5/30 Mobil 1 oil and no oil additives.
The rattling noise is louder when I remove the oil fill cap, but is definitely coming from the chain area at the front of the engine.
So I suspect a guide has broken or a bolt came out as previously mentioned.
I will pull and check the cam phasers and the valve cover this weekend and see what I’ve got. If guide(s) is the problem, Can I replace all the guides and re-use the chain with only 3,000 miles? Or just start with all new stuff?
I am also trying to figure out why both cam phasers appear to work normal but stops displaying any movement after getting up to operating temperature. Thanks

Change the chains and guides and as I posted install the ZZP front guide and a replacement bolt for that upper bolt in the front guide.

Both are included in this kit
