    Changing spark plugs in '97 5.4

    Isn't it nice that some of the new plugs like iridium and platinum can go for up to 200,000 km or 150,000 miles +/-? Some of the modern plug jobs are 'stand on your head' workouts, so in my case at 255,000 miles, I may never have to do it again.

    ... Or is there more to the cold weather pvc system than simply changing to the double pcv hose config?

    1997 Expy 5.4 PCV Valve to Where?

    EXCELLENT! Thanks Hamfisted! You varified my suspicion. The 'cold weather' PCV package is what I was calling the heated PCV config. I suppose I could put that cold weather hose on there? Calgary gets cold enough for that I bet:) Thanks again. tinkering

    I I don't have time to wait for new hose but thanks for that. The mystery remains... What is that vacuum fitting used for?

    1997 Expy 5.4 PCV Valve to Where?

    I decided to build a PCV hose out of the old one. You can see I put a smaller hose inside the 5/8 hose which fits the fitting on the back of the intake manifold. I then fit a plastic PVC valve elbow I had in my stuff into the 2 hose piece. Then fit a little larger diameter hose over the fat end...

    ... but I forget what came off of the vacuum fitting under the throttle body area (visible in the 3rd pic)?? I can't find anything that lives there.

    1997 Expy 5.4 PCV Valve to Where?

    The homemade fitting was the rotted rubber boot (just like jelly) of the PCV hose stuffed into the clear tubing that was on the metal vacuum fitting at the back of the intake manifold. Amazing contraption; it was still able to run well but was not breathing. I suspect it caused a lot of...

    1997 Expy 5.4 PCV Valve to Where?

    Hi, 1997 Expy 5.4 1st Gen The PCV valve vacuum hose has presented me with a problem. I just finished replacing the plugs on the passenger side and was putting wires and hoses back on when I got to the PCV valve. I pushed the vacuum hose back on the PCV valve at the valve cover but the other end...

    Changing spark plugs in '97 5.4

    I hope I'm not repeating some info that's already been posted in this thread. It's late and I am too tired to read the whole thing. On my 1997 Expedition 5.4L I managed to change all 8 plugs without removing the fuel rails on either side. Let me say, it took me quite some time and if you don't...

    Those Little Specialty Bulbs in Headlight and 4x4 Selector Switches

    1997 Expedition XLT 5.4L 4WD 440,000 km 275,000 mi YES! I recently took the dash apart to replace bulbs and fix other things. Where the heck does a guy get those funny little specialty bulbs that fit into the headlight and 4x4 selector switches? I have some on the list for my next pick yer part...

    Power Distribution Relay Box?

    Well, that was easy. It was the first one I tried; the only large one, at the top right. I knocked it around a bit and I worked again but I replaced it with the known good one, just in case.

    Power Distribution Relay Box?

    I know this thread is 4 or 5 years old but I am having probs with running board lights too. I think I might have a similar relay box to 'the unicorn'. Mine is Oct 1997 (XLT). There are two rows of relays, see picture. How do I find which one is the culprit? I think I might just run a known good...

    The Infamous Expedition/F150 Windshield Leak

    I am going to get a caulking gun size tube of windshield sealant and try to go all the way around under the rubber seal. The most important part like always is cleaning and drying under there first. I need a new windshield but don't want to spring for one yet.

    The Infamous Expedition/F150 Windshield Leak

    One place it water gets in for sure is where the roof channel (run parallel to the roof rack rails) meets the windshield seal at the top. It works it's way along the top and down the pillar into the under dash area. Commonly does damage to the fuse box and GEM, causing all kinds of electrical...

    The Infamous Expedition/F150 Windshield Leak

    No 4x4 Low Indicator, No Actuator Movement 97 Expy

    I found where the windshield leak is. It's where a channel (that runs the length of the roof parallel to the roof rack) meets the windshield at the top seal. There is rust there too so the leak could come in anywhere. I might seal it all around. I am going to get some windshield sealant (black...

    No 4x4 Low Range or indicator light

    I think the LowRange problem was related to the corrosion in the GEM which is caused by the infamous water leak from tbe windshield. I thought I heard it was where the bottom of the windshield meets the dash but I think it makes more sense on mine that it is leaking water in at the roof line but...

    Apparently my Expedition doesn't like the rain

    I can see where this seal is leaking under the rubber at that channel on the roof, as well as other places likely where there is rust happening etc. After cleaning and preparing along there, what is the best sealant to apply in there? I need a windshield something fierce but don't want to...
