'89 GT Upper Intake Leak - Pics (HELP!)
Need some help. What is causing this leak? What all do I need to take apart to replace these gaskets that appear to be leaking (if they are not gaskets, what else is going on here)? I have 4 Mustang books (Haynes included), but cannot seem to figure out where I need to look. Nothing is helping too much.

How much work is involved in this? I have some manuals, so if you can give me a subject, I can look for a how-to. I don't see anything under "manifold".
I will say that I have had the following problem that I have yet to get rid of:
In the last year or so, my RPM has stuck at 2K idle for a minute or so. This has happened only twice I believe. It was pretty bad but went away.
When I am driving, and I throw the car in neutral and coast, the car will idle at 1,200 RPM or so for a bit and then finally drop to 900 or so. Not sure if this has anything to do with that residue. The car only has 24K original miles on it.

Someone on another forum said,
Are you sure its leaking? When is the last time you cleaned that area off. Some purple power or simple green and a garden hose should get most of that residue off . Then if it comes back in a short time I would worry about leaks. There really is no oil of fuel flowing thru that part of the intake, if you have a leak you should see a problem with vacumm like the previous post states.
I am not positive that anything is leaking, but what is all that residue?

Mostly dust particles and dirt. What the residue actually is makes no difference. The fact that it's sticking to a gasket mating surface points to a bad gasket. The fact that it's an upper intake gasket points to PCV system.
