I can't believe the dealer is giving you that hard of a time. My local dealer would have had you fixed and on the road with new timing chains, tensioners, etc. If something doesn't get fixed quick, in my opinion, the entire engine will get trashed. I would go to different dealerships until someone at least done SOMETHING.

Great thread…I am piling on. Apologize ahead of time for long post.

I had/have the cold start up rattle in 2011 SCREW Ecoboost. See my OP below.

https://www.f150forum.com/f102/p0016-eco-timing-chain-267738/

I installed new primary and secondary chains, primary and secondary chain tensioners, and all new chain guides. The only pieces I didn’t replace were the cam phasers.



I have about 2,000 miles on her since I replaced everything and it has been whisper quiet….UNTIL 2 days ago. I started it in the garage and thought I heard something, but I ignored it, because I thought it can’t possibly be that noise! Yup, did it again this morning. It has also developed a new noise. If I hold the engine right at 1,000 rpm’s, it gets very noisy…like lifter rattle. Above or below that rpm and the noise disappears.I currently have no engine light on and it is running fine.

So, here are my observations having done this work myself.

Primary Chain – I measured my old chain against the new chain (you can see my method in OP linked above) and found old chain to be @ 1/4" stretched.

Primary Tensioner – The plunger was fully extended.

After seeing the primary chain stretched and that the tensioner was completely extended, I was 100% sure that the chain stretched so far that the tensioner was unable to take up the slack causing the terrible slapping sound. Now that it is making the noise again, I can’t think that in only 2,000 miles of driving the chain has stretched out again.

I have seen lots of people blaming the lack of oil pressure at startup for the noise. I sort of agree. The main tensioner does use oil pressure to push it out, but it also has a pretty healthy spring in it to keep it extended against the pressure arm guide keeping the chain tight. It seems to me like this would likely be enough to keep it from slapping while starting in the absence of oil pressure. Furthermore, the teeth on the plunger that keep it from being pushed back in are quite small. So, the most that the plunger could be pushed back in would be slightly less than the distance between 2 of those teeth. My point being that it doesn’t seem like that small distance would be enough to allow for that slapping in the absence of the oil pressure.


I really want to get this fixed/help others find a solution here. I love the power this truck has and the cabin room, but it is getting dangerously close to living somewhere else!

I think if I had that noise, I'd take the truck to the dealer and tell em I'm gonna lemon law it. If Ford doesn't have a fix then how can they refuse to lemon law it?

In my state, I believe you have to have seven unsuccessful attempts at repair before you can begin the Lemon Law process. If they won't even attempt to fix it once, Lemon Law isn't an option.

Alright, finally got the truck back today. They did the TSB for the intercooler, replaced the coil and spark plug on cyclinder 4, oil change, replaced the tensioner and chains, all four phasers, valve cover gaskets, intake gaskets, water pump gasket, crank seal and bolt.

Paperwork said the timing chain was stretched and the teeth on the phasers were worn, and the tensioner had 5 teeth on it.

Seems to be running well... for now.

Take a look at your HPFP and that camshaft area. It is possibly you have a damaged camshaft. IF you flatten or score it will make noise.
But I'm betting the tensioner let go and is damaged some along with the guide material missing.

That's great you got it fixed! I can't remember if your truck was throwing error code P0016 or you just had the rattle?
