2.4 Intake manifold removal

Hi all, wife's 2013 Equinox has a clogged PCV. Dealer confirmed it, but they want $630 to remove the manifold and clean the PCV orifice. I feel comfortable doing it myself, but are there any "gotchas" I should watch out for? Seems the high pressure fuel pump has to come off, but it's not clear if I have to open the lines. I know if I open the lines I'm supposed to replace the line. I know to rotate the engine so the cam that drives the pump is at the lowest point. I am ordering the Haynes book at least to get torque specs. Fortunately it hasn't blown the rear seal, but looks like I'll have to fix it before winter comes again. Stinks that GM has a service bulletin but I guess ours is not one of the ones that qualifies for the free repair, even though it's having the same problem.

I took the IM off my 2010 Traverse to replace the spark plugs, and that was very straightforward, but it didn't have the fuel pump in the way. Other than replacing the gasket and making sure dirt doesn't fall into ports, it was pretty easy.

Are you having any oil consumption issues? If so, you might want to get the dealer involved in the oil consumption test as I think I've read the 2013's are the last year that are covered under the extended warranty for that issue. If you're having only minor oil consumption, cleaning the PCV orfice may resolve that. In any case if you decide to do the job yourself, don't buy any parts needed from a GM dealer as that will leave a paper trail that they can use to deny any extended warranty in the future or even litigation. Genuine GM parts are available from 3rd party vendors like Rock Auto or even Amazon.

I have a 2012, 2.4, looked into removing the intake manifold. There is an ac line that runs right in front, and that needs to be disconnected which involves evacuating the ac system...never got a solid answer though.

Tank is right. My Alldata says that the AC line will have to be removed as well as the low pressure fuel feed pipe from the fuel pump. A few things will need to be repositioned but the fuel pump can remain on the manifold. Removing the studs will allow the intake manifold to be removed without removing the fuel pump.

Thanks for the tip, Garagerog. Yes, it's having an oil consumption problem, but apparently not enough to qualify for any coverage. About 2 quarts in 2000 miles, which GM considers "acceptable". Still more than my 42 year old MG uses per mile, and I need a catch pan under that because it drips on the garage floor.



AC line? Well, that's a head scratcher. The AC lines are far from intake manifold. There's even a Youtube video on removing it that doesn't involve disturbing the AC lines. Exhaust I could believe, but it looks like there's plenty of room to remove the intake. Only thing thing that bugs me about the Youtube video is the guy doesn't seem to take any precautions with the fuel pump, just cracks open the high pressure line and unbolts it.

sparky dave, i guess there are different ways to remove the intake manifold. step 13 in Alldata says this: 13.Remove the A/C line nut (1) and line (2) from the compressor and reposition the line to the side. ?It does show the AC lines from the compressor being disconnected. Personally I would do anything I could to avoid that myself.
Not sure why if it is as you say. I'll have to look at my 13 nox 2.4 tomorrow to see what this is talking about. Maybe Tanks 2012 is different than the 2013.

that doesn't sound right, when I had my oil consumption work done I was told by my dealership and was able to confirm it online that if your terrain/eqiunox burns 1.25 quarts or more within 2000 miles you qualify. see this TSB

This is for a 2011 but I am pretty sure its the same threshold for the 2012. So if yours is burning two quarts in 2000 miles you should qualify.

There is no service bulletin related to oil consumption in effect for a 2013. They checked, and the only one that we might qualify for one for a power steering problem, which we haven't experienced. I'm starting to think GM is well aware they have problems but they can't afford to fix all of them, so unless it's a genuine safety issue they can only fix some of them and make a few people happy. The dealer knows how much I said it burns, but they didn't offer to do an oil consumption test or give any indication that it might be covered.

Right across the front on the 12' there is a line. I refuse to open the ac system, it's a pita imho to keep dry and recharge correctly, any moisture can easily destroy the system.
