.... the EGR takes exhaust gases from the rear header and bleeds them into the intake manifold. The EGR has a vacuum control pipe connected to the upper intake manifold,(after the TB) that operates it. It originally connected to a whole bunch of vacuum pipes at the end of one of your black plastic pipes on your 2.5L manifold. (the other black plastic pipe went to the brake servo) You will need to find pipes to fit your EGR... where ever it happens to be, considering the 2.5L / 3.0L parts you have installed.
The PCV system sucks blowby gases from the valve cover(s) and normally pipes them to the intake tract before the TB but after the MAF. Some guys put a catch can between the valve cover(s) and the intake..... some just vent to atmosphere. Do not plumb it directly to the intake after the TB because you **** up yer engine.
Sort these two items out first and possibly the servo vacuum feed too, then see what you have left .....G.
Okay,im getting kind of confused but I think I have it set up the way it should be now (for the most part). I already have the egr tube from the exhaust ma idols connected to the egr valve and I have the dpfe stuff connecaswell. Here's a list of what I have connected:
-PcV valve is connected from the rear valve cover to the uim on the underside
-the egr vacuum solenoid has the red/green vacuum lines going from it into a bigger connector on the passenger side of the intake, and then from there along the front valve cover to the egr valve and fuel regulator. Green=egr red=fuel
-the evap relief hose is connected to the uim right next to the IAC.
-the main vacuum on top of the uim is connected to a tree that goes to the booster,hvac,evap, and air intake (I may be missing one thing here)
-the air intake also has a hose coming from each of the valve covers (I basically stole the junkyard Taurus setup and adapted it) the Taurus had 3 lines going to the air intake whereas the cougar only had 2
I think that pretty much sums it up. After connecting everything in this new way(I had it different before) I started the car and I no longer have an engine light for running lean and it seems to be running better. I flushed the radiator using water and coolant flush..ran it through about 15 minutes and my coolant temp was only 150 degrees. Afterwards I drained it and added new coolant (I mainly flushed it to clean what residue coolant/oil mixture that may have been in the system still because I know how Dex-cool is)
