Ok, so when I drilled my weep hole I wasn't sure how deep to go, I went thru the hard plastic and then it felt like it was hitting something harder like maybe metal so I stopped there. I don't see anything coming out but I am not sure if I drilled it deep enough. Anyone want to chime in and help?

all you needed to do was go through the plastic. From what i have read on here, the oily/water combo doesn't always come out when you drill the hole. So don't be worried that nothing came out. It all depends on where you live, if you just drove it recently, and how humid it is outside.

I also changed the spark plugs and the coil boots after drilling the hole. The truck is driving like a champ (and yes Houston is very wet and humid today).

This feed helped me tremendously, I didn't have to take it to the dealership and get lied to and raped on charges and unnecessary parts and labor!

Thanks to all who wrote in here and replied on how to do it and how their trucks were running afterward. Mine was barely moving if you touched the gas pedal much at all, now all gears including passing work GREAT!

Default Driving through water with weep hole

I tried searching for this answer, but could not find any detail.

I live in an area that floods (6-12” typical max depth). Will driving though water pose any risk with the 1/16” weep hole?

thanks- this thread has helped a ton of f150 owners!

I am going to ask these questions simply because this thread seems to be about multiple issues and not the specific one.

I have a 2011 Eco Boost. 139k on it now. Somewhere around the 130ish range, I started experiencing the shudder/Shake, almost like a wheel is out of balance when approching the 55 - 60 mph range.

I see many people on this thread talking about drilling holes, getting wheels balanced the plugs replaced, etc.....

I am NOT an expert and really have not much knowledge about these trucks. What I do know is, in the last 6k miles I have replaced all the timing components, the plugs, Oil, and ford said they lubed the ends of the drive shaft, not sure what that means, but it got rid of a clunk I had when releasing my foot from the brake and transitioning to the gas.

But like I said, I still have this shudder/shake at 55-60 mph. I do find that sometimes is is slight and sometimes it is insane.

After browsing this thread, I feel like I still don't know what it could be. I feel like something with the driveshaft, or still something with one of the wheels, or brakes or something. I just don't know.

Has anyone actually been able to fix this issue, or pin point what it really is?

This thread title is misleading and is actually TWO different issues.
1.) the driveline vibration - most common on the 6.5' bed trucks. This is an incorrect shim on the rearend that causes a harmonic vibration. It is not specific to a particular engine.
2.) misfire/studder/shutter - Specifically on ecoboost trucks and is due to condensate buildup in the intercooler that blows out spark on acceleration. Only Remedy is to drill the intercooler weep hole and religiously change spark plugs every 30k miles with motorcraft sp534 gapped to no more than .030.

Tried reaching all 300 pages and I gave up. I have a 2013 5.0 supercrew with the 55mph steady shake. Have a front passenger tire that is wearing much faster on the outside than other three tires, almost bald. Going tomorrow to get tire and suspension looked at. I've searched and read pretty much all threads over last week regarding this topic. Suprised to not see anything being discussed about the torque converter in the 300+ page thread. Have any of you had that replaced and problem solved? Other threads point to that being the case fix and issue, not spark plugs gaps

Default Finally sold it.

After all of the well-documented engine issues I have experienced with my 2013 KR Ecoboost (and money spent on “fixes” that didnt work), I finally traded for a 2016 Toyota 4Runner, which I will drive/modify over the next 6 months and then give to my son. At that time, my goal is to purchase either a 2016 F150 Lariat or a Sierra 1500. I am going to have to jump over to the forum section covering 2016 models now to see what issues I should be wary of over there. One thing I will do for sure, is always buy an extended warranty on all my vehicles. My 2013 was a good truck for the majority of its life, but I have been disappointed in each of the Ford techs I would take it to (most of whom had no idea of the well-known TSBs on my model), and Ford’s unwillingness to handle the expense of such widespread issues, regardless of warranty or not. Thanks to all for many great posts and advice. May see some of you over on the 2016 section!
