    Was the motor guaranteed running when you bought it ? ....G.
    the motor was from a job nkyard but they said it was running when they pulled it. I'd have to double-check the compression deal but I think the two lowest ones were on different banks.

    But hey you won't believe it but I did a leak down test on cylinder 2 because it was the lowest one and I had no leakage at TDC, so I said heck with it and put the intake on and tried to start the car...and ah starts! It runs a little round but not bad. I'm getting a o2 code for running lean on both banks but I'm not sure if it's vacuum related or not because some of the stuff isn't xonnected, and my egr isnt tighten down all the way. But im just excited to hear it again

      be careful about running an aluminium engine when it's lean .... overheating is a serious issue.

      Try to fix as many issues before you let the engine temp's rise above the blue section .

      Glad to hear it starts.... just the kind of encouragement you need to get it finished ....G.

        I hear ya. For whatever it's worth, the temp gauge was still c
        pretty far towards the cold side and that was after looking getting it run like 10 minutes. But yeah I'm going to connect the rest of the vacuum and see what happens

          I'm going to see about going to the junkyard today so that I can look at some vacuum. Specifically I want to know how the pcv system on the 2004-2005 is connected. I know the valve is in the rear valve cover, but I want to know where it connects to the intake. My original assumption was that it connects on the rear of the intake but if that's the case than it is pretty hard to put on because there is next to know room. Also, I'm wondering more because i seen that the hose on the 2004-2005 is much longer than in previous years. Furthermore, I have a inlet/outlet port on the passenger side of the intake right next to the egr vacuum solenoid that I still don't know what goes to. I posted a picture of it once and in that picture (from Google) there was a hose going from it to somewhere along the driver's side of the engine

            .... 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)

                .... sounds like you have everything basically in place.

                As long as the idle is steady and not too high and temp's are good.... you seem to be heading to putting some miles on it and just monitoring the engine.

                Are you planning any mods ? have you got any plans for fine tuning to your basic remap ? .... although you can run a 3L on a remapped SVT pcm ... some guys reported that having it dyno tuned really sharpened things up ....G.

                  The idle seems pretty decent. I haven't revved it up to much yet but I'm kind of babying it for the moment. I actually got a tune from npg. Joey said that there isn't much point in going to a dump because he can do just about anything. He does know quite a bit but yeah. I already got quite a few mods. Headers, y-pipe, magnaflow, cold air intake, etc. I may do a turbo but that's down the road. After this is sound I'll probably do something with the trans

                    .... it's a shame Joey doesn't have a dyno .....

                    Hmmmmm; I might invent a home dyno set of rollers anyone can have in there garage........ could really take off,

                    quite literally if not strapped down Ha ha ....G.
