2015-2017 F150: Vacuum Pump Oil Leak Repair (3.5L EcoBoost)

This 2016 Ford F150 3.5 EcoBoost had an oil leak on the passenger side of the engine. It gave off a strong burnt oil smell whenever the vehicle was at a rest with the heat or a/c running. It initially appeared to be coming from the valve cover gasket. I replaced the valve cover gasket, but the problem persisted. I then removed the brake booster vacuum pump to find the large o-ring deformed and apparently failed. I replaced the o-ring and applied the recommended silicon to the joining metal surfaces. I have since put several hundred miles on the vehicle and the problem seems to be resolved. No more burnt oil smell coming in through the cabin air ducts. No more oil residue on the engine or garage floor.

Replaced the pump on my 2016. Removed the inner fender liner, EASY access! I had the old one out and new one in, took me about 20 minutes. No issues for a week, now today I am getting the burnt oil smell again!

Great Video! I had a oil smell that was slowly getting stronger, had no oil leaks under the hood, watched this video, went and verified that this vacuum booster was infact leaking and now am buying the seal.

I have been trying to figure out where that leak and smell was coming from. I could see it but had no idea what it was. Thanks so much. Awesome....

I can't thank you enough for this video and information. I've seen that so many folks have spent endless amounts of money trying to identify this exact situation. And I darn near became one of them. Outstanding post!!

Nice quick informative video, no 10 mins of babbling BS. Love it! Thank you

This video was very informative. Unfortunately it did not fix my oil leak that appeared to be coming from the Vacuum Pump. It took me roughly 2 hours to complete this job. I think actual valve cove will be next. I just purchased my truck used from a Ford dealership. On the test drive i told them I smell fresh oil burning on the exhaust. They assured me it was residual from a valve cover gasket replacement. So i allowed a week to go by to ensure it was residual. Unfortunately not. So I did the vacuum pump seal 2 days ago, and cleaned all excess oil from the back of the head, block and exhaust. Still leaking.... thank you for your video.

Just had mine replaced. That pump and both valve cover gaskets 1100 dollars! No more stinky smell with the heat on.

Thankyou sir! Dealer tried telling me it was rear main seal leaking.. i got under today and traced up to there and didnt know what it was leaking.. i will now be able to fix myself.. thanks!

[scottbrewer]

Great video, very informative. I have the same leak and couldn't figure out what the hell was actually leaking until I came across your video. Thank you for posting this info for the rest of us!!!

I just installed one of these bad boys and had no vacuum whatsoever, I realized I might not have aligned the pump in the first place IDK. Im about to redo this again with youre instructions. Thanks friend!

[rickymulch]

Thanks For the video I thought for sure the rear main seal was out, what a relief !

[jason]

Thanks for the video buddy! Kept smelling burning smell and oil dripping on exhaust. Finally going to get this fixed

[D-Allen]

Great video. I biggest concern of doing this was wrecking the vacuum hose connector due to not knowing how to disengage/disconnect it.I've seen others show that they broke the white tab taking it off. Showing that makes all the difference to me. Thanks!!

Good video man. I have an oil leak dripping in all the right spots, im gonna order that seal and just change it first because this looks the most possible. When i run my auto start the inside of my truck has smoke in it from the oil hitting the exhaust manifold

[MotoTaco]

took me halfway through to realize you were using a mirror! lol. Recently have seen and smelled smoke coming from my passenger side every now and again and couldn't see where it was coming from.

more often than not.. the oil leak is coming from the back of the vacuum pump housing. not the o-ring seal where it meets the cylinder head. sooo replace the whole pump... not just the $10 gasket.

[jimhendrix]

I've read to change ALL the gaskets... including the one on the outer casing?

[jorgemartinez]

I just replaced the pump on my 2013 F150 EcoBoost, Personally I would not just replaced the gasket, apparently after reading some Forums they also leak from the back. Also changing the pump this way is the hardest way to do it, If you remove the passenger side wheel and wheel well, it's easier to reach and remove the bolts.

I noticed oil on my drain pan and transmission area.
Didn't see the leak source but it is more on the passenger side.
Thought I'd look on YouTube and boom "vacuum pump oil leak" seems to be common to some degree.
Looks like an easy fix I suppose.
Looks like I'll be buying me this o-ring soon.
