I notice when trying to get the crank back to the 5 o'clock position that there comes a point where it gets very stiff to keep turning the bolt, more or less when the dot is at 12. Is it safe to keep giving it a go to get back to the correct position?

Try going in reverse. Not a good idea normally but nothing should feel right so give it a go. Perhaps turn all the cams so they are neutral or not pressing on any buckets. 12 will put the number 1 piston at tsc so don’t do that yet. 9 is where you want the notch for the dowel

For the last week, Ive been letting my truck idle for about 3 minutes at the end of the day before heading in. Since doing this, Ive had no rattle in the morning. My buddy gave me this tip and it seems to be working so far.

I have often wondered if it doesn't hit the right timing or something on shutdown and so the pins on the phasers aren't locked in right on next startup. Interesting tip. I may experiment further with this. [emoji1303]

Could be anecdotal, but it's both harmless AND potentially good for cooling down those turbos and the benefits that could offer.

It is but nonetheless it is not a bad thing at all to do

New here and new to the Ecoboost world. Just purchased a 2012 F150 knowing it had timing chain rattle for a good price. I have been looking at the forum and didn't see much (if anything) about engine failure due to the timing chain stretch issue, but maybe I missed it. I have a couple of questions:

Do people experience failure or just loss of performance and noise from the timing chain stretch?
Does the timing chain rattle get worse or last longer as you put more miles on the truck.

Right now I have the P0016 CEL and the timing chain rattle is noticeable but not as loud as some of the videos that have been posted on the forum. Is this something I need to address immediately or can it wait awhile.

Depends how bad it is. This can be seen in variable cam timing intake bank 1 PID reading. +6 degrees is as bad as you want it to get. You will eventually see piston to valve contact

Change oil every 3000 with Motorcraft full synthetic and a Motorcraft filter.
Hold accelerator to floor while turning engine over until oil pressure builds, then left off the accelerator so it starts.

If you're seeing that code. Possibly change the solenoids on the top of the valve cover, if that doesn't cure it then yes you need to do the job, your power etc will be limited and the chain is stretched too much. There has been a few chains that have let go completely.

Ok folks. Here is why cam phasers rattle. Proof and best pic I’ve ever posted. This worn “ramp” doesn’t allow locking pin to fully seat when shut down. Therefore upon cold soak, lack of oil pressure from excessive drain back of oil and the phasers not seeing oil pressure fast enough, the pin isn’t under enough force to push in the locking groove, therefore since it is not upon shut down of truck, the phaser clack first a few.

This is good info, we will have timing chain kits out in about 12 weeks.

1- they address the weak primary chain.

2- they address the accessible and unnecessary amount of drain back on **** down and any length of cold soak

3- they address secondary tensioner issue we found (more on that once we have run the engine dyno and confirm what we have already but with data)

4- secondary chains will be addressed and we break them (or have on 4-5 builds (seemed like 1 then bam bam all in a row and all 600 ish plus HP)

5- we will offer stronger cam phasers to not allow the backing plate to wear as seen. Pin is designed for like 2-5 million key cycles hence why plates worn.

6- we will offer cam limiters. 60 deg of movement on intake cams is A LOT and 40-50* deg is more than enough

7- better tensioner (primary) helping harmonics and wear thru tensioner that is actually smooth and doesn’t move in and out so much, hoping to reduce 80% of the oem movement

8- adjustable lockable cam gears will be available for big boys with big things and big sticks (bump sticks that is)

9 billet guide pass side and possible billet guide driver side with e85 comparable guides and wear strips

They are NOT Ethanol safe

I have a 2013 F 150 Limited, it started rattling 10mo ago. Fortunately I have an extended warranty, so the fix will cost me 100.00. The rub is unless the dealer personally hears it they won't cover it, and it happens often but not every time. Went in for coolant leak, and coil boots. When they started the truck on second day it rattled like crazy ( mechanics words ). Now I'm told Ford doesn't have the parts due to covid effecting production. Now water pump and tensioners are on hold. They gave truck back and said watch coolant level till timing chain kit finally arrives. SMH

Hmm. We use a large distributor for parts and have no issues

I believe it's called "getting the runaround."

I think there is a real thing going around that just seems so evil. Some things available at a walmart 30 miles away are still not in stock at the local walmart. They are still blaming wuhan-corona-covid superdooper worse than anything ever known to mankind flu virus.

Im going on my 2nd week without the rattle when allowing truck to idle for 2 min b4 shut down. Prior to doing this, ive had the rattle on every cold start since i boughtvthe truck 8k ago.

I bought my 2017 Lariat 3.5 Ecoboost 8/6/20 w/ 52K miles. It was a CPO truck, but obviously had been used as a tow beast. The first morning I started it, I heard the rattle. Several days, several videos and the dealer finally said; bring it in. It sat there 2-1/2 weeks before they finally got the parts. Just got it back yesterday afternoon. Hoping the fuel mileage improves w/ the new phasers.

Are you saying the rattling was caused by using it as a towbeast ?

After all the work, including another unrelated issue that came up and is posted on a different thread, I started the truck after confirming oil pressure and priming the fuel pump and even though it seems to be idling fine I am now getting code P0017.

I'm attaching pictures that I took during the install maybe someone can catch something I'm not seeing. One thing I did notice is that there's a loud buzzing type sound coming from the PCV line on the RH valve cover. Here's a video link for that noise:

Wish I had more time for this, I almost feel it could be an electrical issue, is that possible with that P0017 code? The solenoids were replaced as well.

Including my previous post above, but have one other question.

I took the truck a mechanic to run diagnostics. Mostly, I was interested in what the timing was doing to make sure it wasn't a simple sensor or something throwing the code. The cam and crank sensors were communicating and transmitting the same timing numbers. When looking at the timing during idle it was jumping around sporadically ranging from 0 - 10 degrees out. Is this indicative of a stretched chain or something else.

Thanks for the help.

Also, I had the truck scheduled to get the timing chain replaced and was told that the phasers are on back order for 2-4 weeks. So I am not also playing the waiting game for parts as someone else mentioned recently in this thread.

Still ignoring my rattle, now at 113,600 miles. So that's about 50k miles and almost 4 years of either ignoring or avoiding (foot to the floor method) the rattle. No noticeable difference, but I do use the motocraft filters and Mobil 1 5w30. Still only 3 things that matter on the rattling - time, temp and how long you crank it over. Embarrassing to crank over your truck for 10+ seconds when there are people around, but better than the death rattle and better than dropping $2700+ when the truck runs fine. Hopefully a tree falls on it and I get a big insurance check. One minor change - I did notice more metal dust (very, very fine particles) on the magnetic drain plug last oil change... that plus the developing rust may convince me to trade it in on a 2015 with the 2.7L.....

OK finally gave in. Got it fixed at 118k. What finally pushed me over the edge was the constant loss of power. I guess that is what happens when it gets REALLY stretched out. So for the record I went just over 55k with the rattle. The power loss went from occasionally to consistently to constantly, to the point where when I drove it to my independent mechanic to get it fixed every time I let all the way off the gas it went into limp mode. I bet I put it in neutral and restarted it 30 times in 60 miles. Glad my wife was following me or I may have been shot at. Mechanic said the chain was insanely stretched, he couldn't believe it still ran. So I guess I milked every last mile out of it. He said slight damage to the phasers so he replaced them, also did the secondary chains and the internal water pump.

I've put about 4k miles on it in 6 weeks (including a 2k trip towing a camper) and other that a recent check engine light it's been great - no rattle, great power, 20+ mpg when I baby it. Mechanic did it for $1800 but I promised not to share his name to other ecoboost guys because he says he HATES doing the job He did it for me since my family has been using him for years. Your time is coming, @snakebitten

 

[grover738]

Regarding temps as a contributor to rattle, is it higher temps that cause more rattle or lower temps?

Higher for sure. When it's really cold (like sub 10 degrees F) it didn't rattle at all.
