If you don't mind sharing, what did you use to plot those charts?
I used good ole Excel to create those charts. Just select the columns and click insert chart. I selected the 2D line chart.
Glad you finally tracked the leak down. I would just silicone those areas and see if that takes care of the issue and maybe check all the mounting bolts on it to make sure they are tight before using silicone on the problem areas.
Also, each intake does have it's own o-ring/gasket and most automotive stores carry the manifold gasket sets.
Unfortunately, I don't think a manifold gasket set is going to make it stop. It's not leaking from either the upper or lower intake manifold gaskets. I sprayed those down really well with no change in O2 sensor results. I also checked the torque on the bolts. All were good at 89 in/lbs. I gave them all a tiny bit more of a turn but it didn't make a different to the problem spot.
Those two arms adjust the air mixture going into the cylinder. The air is leaking around that pivot point. I can't really even get to the shaft because the arm is in the way. That little arm that's sticking up connecting to the plastic is welded on. So I can't even remove it to fully access the shaft.
Bummed that it also looks like I can't buy the manifold runners separately. On top of that, looks like the dealer is the only one who sells the full intake manifold. I found an aftermarket one for the Mustang (it's the first picture in my previous post), but not for the Explorer/Mountaineer.
I'm going to the dealer tomorrow to get the cost of the manifold. I'll also ask their service department how much it'll be to put it on. If it's not too bad I'll make an appt, otherwise it's my next free weekend project.
Has anyone else had a leak from this spot on their intake manifold? Or am I the only lucky one so far?!
