    1997 lean condition

    I just went through this on a 5.4. Same symptoms anyway... Did a smoke test and found a minor vacuum leak at the intake manifold. Replaced the manifold and gaskets and all is good now.

    2001 5.4 2 Valve Intake Manifold / Valve Cover Gasket Job and Parts List

    Good idea and that'll certainly work but pics on the phone were easier for me as I tossed all of the bolts in a bucket of solvent to clean the crud off of them while I was working on other things.

    2001 5.4 2 Valve Intake Manifold / Valve Cover Gasket Job and Parts List

    All back together and so far I've driven it about 100 miles with various types of driving with no CEL! I think my problem is resolved! So far I haven't noticed any rough idle on cold starts, I'm pretty confident that was intake leak related. If you're doing this project I would recommend taking...

    I’m not sure about the crossover gaskets. I went with a new intake which comes as a complete assembly with the crossover already installed.

    2001 5.4 2 Valve Intake Manifold / Valve Cover Gasket Job and Parts List

    Update! Tore everything down last weekend. Got the intake and valve covers off, was pretty painless for the most part, worst part was getting to the last couple rearmost valve cover bolts on the passenger side. I also had a problem with the thermostat housing bolts being seized up. Broke the...

    This is the intake manifold on mine. The throttle body which sits on top of it is alluminum. Weekend project for sure.

    2001 5.4 2 Valve Intake Manifold / Valve Cover Gasket Job and Parts List

    Yeah this is my second 1st gen expedition. I got close to 300k out of my first one and it was still running strong with original engine/trans when I retired it but everything was rusting out around the drivetrain. I picked this one up about a year ago. It’s pretty clean and has lower miles so...

    Got it! Thanks for your recommendations. Genuine Ford manifold on order. I’m definitely not prepared to pull the heads but I will give them a good cleaning while I have everything apart. I don’t have much in this vehicle and mainly just use it to tow my boat so I’m not going to sink a bunch of...

    Thanks for your input. You scared me away from the aftermarket. I found a genuine Ford one on eBay for 225 shipped.

    2001 5.4 2 Valve Intake Manifold / Valve Cover Gasket Job and Parts List

    After doing some more research I feel like it would be a good idea to go ahead and replace the intake manifold. Looks like OEM Ford is around 400 bucks ouch! Does anyone have anything to say good or bad about the aftermarket by dorman and others that I see on rock auto?

    2001 5.4 2 Valve Intake Manifold / Valve Cover Gasket Job and Parts List

    Thanks for the reply but just to clarify- mine is leaking air in at an intake port, not leaking coolant as far as I can tell. Is it advisable to replace the manifold anyway if it’s being removed?

    2001 5.4 2 Valve Intake Manifold / Valve Cover Gasket Job and Parts List

    So I have this truck which has been giving me lean codes on both cylinder banks for months and I finally want to fix it. I looked all over for the obvious leaky vac hose or boot but found nothing. After doing a smoke test on the intake plenum it appeared to be puffing a little smoke from beneath...

    Can't tell which wire is NEG/POS on speaker wires

    Easy way to test speaker polarity Use a 1.5 volt battery (C,D,A cell). Test by connecting your battey to the pair of wires going to each speaker at the head unit. When the speaker travels outward observe the + and - markings on the battery compared to your wire colors. Outward travel =...
