Strange ticking noise

[FaSSt9602]

So I had the Flex at the dealership about a year ago for a few things, one being a ticking noise at start up.  They said they couldn't replicate the noise (not sure how, it does it EVERY time...) and said everything looked in order.

Fast forward to today...the noise is still there, seems a bit louder now.  It will tick 6-8 times.  It sounds like a metal on metal tick, clank, etc...and no it is not the blend door click, that is a separate issue.  :blink:  So a few weeks ago, it made the same noise when I was playing around.  It did it at about 5000rpm and I backed out quickly!  The sound is like a brass check valve closing if you have ever heard that, so my mind went towards possibly a WG issue?  I could see something like that at full boost if the actuator is having issues, but not sure why I would hear it at startup.

Anyone heard/hear a noise with their car?

There's the constant ticking noise the HPFP makes, but haven't heard any ticking other then that one...which kinda caught me off-guard when I first heard it.

I hear it too.  I freaked at first.

Nope.  Not constant.  Does it about half a dozen times each time you start the car and it has done it a a few times on some WOT runs... At the dealership now or I would get a video of it...

Beside the HPFP clicking noise, the 2nd thing is the cam Phasers. They'll clatter for about a half 2nd on start up, and thats normal. But if still audible long then that, a oil change maybe in order. Todays cars are very finicky about the oil and filter you use, while oil pressure is critical, flow is just a critical. And this where all filters are different. So I recommend motorcraft oil filters and a quality synthetic oil of manufactures weight spec.

We'll  see what they come back with.  It has done it for as long as I can remember and the dealer has done all oil changes except one...

You using full synthetic over Motorcraft semi-synthetic? I just did my first oil change and I was thinking about this -- wondering if I should get the next oil at dealership to be full synthetic instead.

I switched right away from syn-blend to full synthetic.  Motorcraft that is.

I been using royal purple.

Well the dealer is taking a serious look at the noise...they aren't sure what it is yet, but they said they don't really like it...Updates tomorrow hopefully!  :-[

Hope it is a good update!

Me too, I've been using Royal Purple, only difference is I have also been using Royal Purple filters.  Just FYI, I change oil and filters at 3K intervals.

Nice to know they haven't dismissed the noise...hope they can find it and get it fixed quickly for you.  Keep us updated.

Well came back that they found a "memo" Ford put out about the noise being known, but and not affecting the life of the motor... :angry1:

When I get a copy of said "memo", I will scan it and post it up here...

Why are you guys using fully synthetic? The only car I use that in is my blown mustang and the oil temps get upto like 280 degrees on wot runs in the summer. What kind of oil temps are you seeing?

From what I understand, normal oil starts off as regular oil and then viscosity enhancers are added to reach the desired viscosity. These viscosity enhancers gradually diminish from the first time that the engine is started until you drain the oil. That means that the engine is subjected to additional wear due to the oil viscosity changing and not providing the same lubrication as when it was new. Synthetic oil is engineered on the molecular level to be a specific viscosity, so it doesn't have these viscosity enhancers that break down. That being said, with synthetic oil it retains it's viscosity throughout the life of the oil change and the only reason you need to change it, is to remove the carbon and other deposits and accumulate in the oil.

I guess I got a little off topic there, but I was attempting to answer the question on the previous post.

In my 2013 SHO I have heard that ticking noise a few times during crank up after the car has sat for an extended period of time. I have ran full synthetic Motorcraft or Mobile 1 oil with Motorcraft oil filters from the first oil change. The car has 36,600 miles right now, and it seems that I have heard the noise more when the oil was toward the end of it's life span.

To me this noise sounds very similar to the noise that is made on a high mileage engine during a cold crank when someone has went about 8-10k on a single oil change.

Would be nice to crack open the valve covers and see what's going on.

 

[FaSSt9602]

Mine is probably more noticeable when it the car is cold (or as cold as it can be in Arizona), but the thing that really gets me is the very random times when I hear it above 5k rpms.  That's when I really don't like it! :'(

When you are hearing that noise at 5,000 rpm, does the vehicle fall on it's face for a second?

Since my SHO is not tuned I regularly run 87 octane in through it. One time I got some bad gas and when I had it WOT the engine detonated at around 4,500 or 5,000 rpm and then fell on its face for a split second and then a let off. I did this a couple more times on that tank of gas with the same results. After I filled up again, it has never done that again. If you are not familiar with the sound of detonation, it sounds like a marble rapidly bouncing around inside your intake. The only problem with 87 is that it is not always 87.

My Flex does it to on cold starts. I had my wife start it with my face in the engine bay. I swear its coming from yhe throttle body. I did notice if I turn the key all the way to on and push go pedal to floor twice it is alot quieter.
