6.7 Vacuum Pump Gasket

[01yellercobra]

Just a heads up to the guys with the 6.7 to check the vacuum pump bolts. It's on the front of the engine right under the intake. I took my truck in for the recall and was told the vacuum pump was leaking oil. I checked it this weekend and it was weeping more than leaking. Two of the bolts were loose and took 2-3 turns to tighten. I cleaned everything up and will check back next week as I'll have about 1000 miles on it by then. Hopefully I caught it early enough.

Figured I should follow up with this. I checked after a couple weeks which was a touch over 1000 miles with everything and no more leak.

Funny story. Mine started leaking on my 15. It happened during my busy season, so it was meet with a "it'll be ok, its not that bad."

Well, as soon as the season wrapped up, the wife and kids and I had a work vacation to pick up a genset in Texas with the truck and trailer. So we took off. Somewhere close to Texas was a quick little traffic jam, where I got hard on the brake, and then back on the gas.

My dash immediately pops with low oil pressure when that happened. Pull off, and yup, two gallons were needed to get back to full. We kept going to Texas, got the gen set, and headed home, adding another 2 gallons on the way back.

What year do you have? Wondering if it affects certain years

2015. It definitely affects the 2011-2016. I'm not sure about the 2017+. But better safe than sorry. On mine it's easy to spot with a flash light looking under the intake tube. It's one of the things I'll be checking when I'm doing the last bit of maintenance before heading to South Carolina.

At least it's not a difficult/expensive fix.

As long as you don't have the dealer do it. They quoted me $1100 to replace that gasket and a drive shaft seal. I said I'll handle it myself.
