I stumbled on this video searching for something else. I wanted to compliment you on your delivery in the explanations.
Thanks a bunch for your comment, I really appreciate it.
Just got me one from Ford Parts Department today and it's now $100 with tax... How times have changed in just a year! thanks for the video, very informative.
I paid 77 bucks today
Bought one at Autozone for $40 works like new
I have a 2013 3.5 ecoboost. Got code P2099. Did notice my intake noise was low and did not hear the BOV sound when slowing down. Did a proper evaluation and all hoses and parts were ok. Pulled the BOV and sure enough the diaphragm had a hole. 40 bucks later and 5 mins under the truck and the truck is back to normal !!(fyi no need to remove the intercooler, just remove the fabric liner).
I'm getting ready to buy a used 2013 3.5. How do you like yours? And how has it been treating you?
Is this the same part for a 2018 raptor 3.5?
I have a 2015 2.7 F-150. It's a different part, same principle, but the boost just isn't there like it was before. The boost gauge never goes past halfway, mostly sitting around a quarter of the way. And it has a hard time staying steady and I feel it when driving. Do you think the valve is bad?
I can't say for sure, but it definitely is worth looking into deeper. I'd take the valve off and inspect if it were my truck.
Thanks for the video. I'm looking at mine now and when 12v is applied to the pins the valve has no movement until I push it down a bit, then it actuates. Shouldn't this valve open and close without assistance?
I noticed that same thing on my original valve when I put 12v on it. I didn't try that to my new one. Yeah, i think the valve should work without assistance, although it would have some assistance when boost pressure is on it.
What problem were you having? My turbos stop producing boost yesterday while driving. I have cleaned and replaced the mass air flows and checked my bypass solenoid. Cause this valve be stuck open causing my boost to leak out while running?
I wouldn't expect this valve to be your issue, as it fails in a closed position. If boost was being built, but escaping then you would definitely hear that leak.
I have a 2013 Ford F-150 XLT with the 3.5 ecoboost. About a year ago, I heard clicking sounds around the front bumper area which ended up going away on its own. I also haven't heard my turbo whistle in quite some time. Everything else on the truck is fine but just wondering if I replace this part, will I get my turbo whistle back?
Of course, I can't speak to your vehicle specifically, but otherwise, this valve does control the bypass blowoff of the turbo pressure, which is where the turbo whistle comes from.
I'm getting ready to buy a used 2013. 3.5 for 11k . How do you like yours? And how has it been treating you?
I replaced the valve, and it works like it should while driving, but I am still getting that electrical clicking when sitting at an idle. Any ideas what is wrong?
It's a solenoid/relay most likely. Sorry I can't diagnose via TH-cam.
I'm hoping this is my problem will be checking soon cause I'm getting the error codes for boost
I would first check your Mass air flow sensor. It's on the airbox duct. Unplug the connector and then reconnect it real good. Then clear your code and see if it comes back. This is a common issue.
After replacing the bov did the clicking on and off go away or did it come back.
It went away and has not returned.
So this is on the 2012 ecoboost as well? My intake comes off the throttle body a lot no matter how tight I get it.
Yes, your 2012 has this valve. 2011 to 2014 are the same 3.5L ecoboost design. It's weird that your intake duct keeps coming off. I've not heard of that before. Are you thinking the boost pushes it off when the throttle plate closes? You could connect a scan tool and watch your MAP (mass air pressure) and see what happens when you let off the gas, especially after a hard throttle pull with good boost.
@@jackharding98 that’s exactly what it does. The boost is so much on a pull and let off like pulling out to pass it pushes it loose. I’ve cleaned the throttle body lip tried to make it grip. Scared to put silicone around the lip to hold for fear of it breaking down and sucking into engine. But yeah I’ll get a check engine light now and then fill a misfire and go check and it will be pushed back usually the bottom part is where air leak occurs. Lotta pressure at that connection under boost. Can’t figure out a way to make it hold.
Mine was making same noise, took it out green seal has small tear. Will replace it but when I do do I need to reprogram my computer as my turbos were loose too. Now I have insane power and the clicking quit. But still gonna replace the BOV.
I don't know about reprogramming the computer, I wouldn't think so.
Ok, thanks for responding, seems no one has that answer🤷🏻♀️. You didn’t have to on yours, I’m assuming???
Mine is same year and mine was doing the ticking sound but not constant, when we took out the BOV and put same one back in it quit.
@loriash9433 No, I didn't have to reprogram anything and no codes to clear afterwards.
i don't see the blow off valve on my 2011 f-150 lariat not even in that location my ecoboost turbo not working
The turbos are different on the 2011 ecoboosts vs the 2013 ecoboost
I have a 2011 f150 ecoboost I replaced the turbos because i thought that would be the problem the turbos won’t whistle or it won’t accelerate. I am not sure what’s wrong with it do you think this is the problem?
Sorry I Don't know what your issue might be, but I don't think this bypass valve is your issue. It wouldn't keep you from acceleration, it's main function is letting off pressure after the throttle is closed.
Did u ever figure it out. I’m having the same issue. Replaced my turbos as well. But little to no boost
@@ralphtime yes I did sir now it’s working like a champ the the turbos I bought didn’t work avoid the auto part store , and now I bought them at the Ford dealership and they worked 👍 and also the vaccum hoses were moved around .. that fixed my problem
@@fordguy1115 what vacuum hoses were giving you problems?
Will this cause a p0299 code and low turbo boost to happen?? How to know if it’s bad or good?? I have a 2017 f150 ecoboost 2.7
Sorry, 2017 2.7L ecoboost is a different generation of engine than mine. I can't answer your question on the code.
Ford mustang 2015 Turbocharger bypass valve ticking noise is normal or no
I don't have Mustang experience, but it's not normal on a 3.5L ecoboost in the F150. I can't think of a reason it would be different on your car, but I can't say for sure.
I got low oil pressure so i took the truck to get it scanned it came up p0035 bypass valve thats what they told me does a bad valve cause low oil pressure or you think it might be something else. Thanks in advance
The blow off valve doesn't have any effect on oil pressure. It is part of the air intake duct.
I got the same problem, did you get a fix?
@@edden3560 not yet, I have it parked but I don't know why something tells me may be is gonna be the turbo so I'm kinda saving to replace it... But before doing so I'm gonna take it to a nearby Ford specialist to confirm my thoughts...
@@josegalindo1262 it turns out I had a blown fuse, it's the F8 one in case that helps
Great trouble shooting, You can do a delete of this valve all together and install a VTA, this will still communicate with ECM , No more codes and the bigger picture is, This VTA (vent to atmosphere) will Save your Turbos, the turbos will not have to deal with blow by Surge!
What…? 🤦♂️
The only thing vta will do that this valve won’t, is make noise. This valve just dumps pressurized air back into the air stream prior to the turbo without the noise.
So how do you know if ur blow off valve is bad ?
In my case, I heard a loud clicking sound near my front bumper when the truck was in my garage in the morning. It sounds like a solenoid actuating erratic.
@@jackharding98 did this solve any issues besides the clicking?
@@bchaveezy There wasn't a problem that I knew of besides the clicking sound and a error code. I think I mentioned the code in the video, otherwise I think it was P014.
Hey my ecoboost is not making any whistle sound when I leave my foot off the gas , any tips what’s going on all vaccum lines are correct??
Sorry, I don't have any info on that situation. Hope you figure it out.
107$ now
I have a doo doo doo noise sounds like my intake but it’s definitely not my rpm’s run high when I accelerate and it makes the noise on and off the gas
