    97 expo dont run right

    The easiest way to find TDC is to pull the plug for the cylinder you are working on, and put a waded up paper towel in the top of the hole ( MAKE SURE IT IS IN LOOSLY as the compression builds it will blow it out ). MAKE SURE YOU STILL HAVE THE FUEL PUMP DISABLED!!!!! Slowly " bump " the...

    97 expo dont run right

    You do not need much, a cap full should be more than enough. If the numbers did not go up considerably, then I would deffinatly say " do the leak down test ". The leak down test will tell you where the lost compression is going that way you know what you are up against. The easiest way...

    97 expo dont run right

    Also the 2 readings from the drivers side look pretty good as far as pressure goes, but the difference between the 2 makes me kinda uneasy. If you can try to test ALL of the cylinders both " Dry " and then " Wet " and post the readings. Try to post the readings with the cylinder number...

    97 expo dont run right

    For those first 3 cylinders on the passanger side do the compression test again but squirt a little bit of oil down the hole first this is called a " wet compression test". What the oil will do is seal any gaps in the rings and if the compression numbers go way up ( closly matching the...

    1997 4.6 overheating issue

    Try to park on an incline with the front of the Expy higher than the rear ( or put it on ramps ) that way any air will " burp " itself out because the filler is higher than the rest of the system ( once you get it full, "bounce" the front end a little bit by hand and that will work the air out ).

    Exhausting Thoughts

    I run 75 -80 mph on the interstate here in southern new mexico with my wife, my daughter that is only 2 1/2, and my son who is only a month old and have never once had them say anything about the noise. With the radio at a normal listing level you really do not hear it very much, unless you...

    motor swap or head gasket change

    It would really depends on the results of the compression and leak down tests. Those 2 tests will tell you the condition of the MOTOR INTERNALS ( condition of the heads, valves, rings, and cylinders ). Why would you consider putting head gaskets on a motor if you do not know the condition...

    97 expo dont run right

    You should be able to test the coils wiring harness with a volt meter or test light WITHOUT the vehicle running. With the key on you should have a constant 12v + the way the coils work is the computer will " pulse " the ground side of the coil to get the field to colapse causing the spark...

    1997 4.6 overheating issue

    A rushing water sound from behind the dash usually indicates that you have air in your cooling system.

    no start

    Sounds to me like you have a bad " starter solenoid ". If it where an ignition switch you would not even get the lights on the dash.

    How accurate is a torque wrench when using swivels

    Kinda confused on you numbering. This is the 5.4 cylinder numbering 4 8 3 7 2 6 1 5 Front of Vehicle here. So passanger side front to rear you have 1,2,3,4 and drivers side front to rear you have 5,6,7,8 Is this the numbers you are using? The...

    Hooking up a sound system, help.

    That connector hooks up to the factory rear door speaker wires to get the signal it needs for the rca's. If you where to leave in the factory HU you could go that way but the stock Ford stereo's actually " cut " the bass out as the volume goes up to keep from blowing the speakers. In other...

    trailer space?

    It really all depends on what kinda bike, and also on how many tie down hooks are in the floor along with there positions. If the trailer is set up for bikes than you should have no issues, but if it does not have the tie downs in the floor ( or not enough ) then you may really want to look...

    violent vibration over 40mph

    It does sound like you are on the right track, and I would not put the blame on the brake change. Some things just happen like that and it may seem like it's related but it's not. One thing that I have noticed with my '02 EB is that it feels a little different every time it gets jacked up...

    New Flowmaster 40 series

    Didn't notice that you have an '05, so unfourtunatly the only thing that you could do would be to try and find some " High Flow " cats because if you try to get rid of yours you will turn on the CEL. If the computer does not see a difference in the readings from the front and rear o2's it will...

    Ford Emblem in billet grille?

    Yeah instead of using washers, I would use a couple of 2" - 3" long pieces of metal ( 1 per mounting bolt ) runing up/down ( vertical ) so that it will hold tighter.

    CB Antennas

    No it is actually a Diesel I wish it was a Firestik since they are much easier to tune, but I have already had this one tuned to the CB when I had the CB " peaked and tuned ".

    New Flowmaster 40 series

    Yeah if you only get rid of 2 out of the 4 you will not throw a CEL but if you get rid of all then you would. If it does throw a CEL ( which it shouldn't ) the only way to fix would be to put in cats or have someone that has tuning software write a " tune " for the computer which turns off...

    Ethanol 85 & 2000 Ford Expedition XLT

    This is going to be something just like E85 - it's optional. The gas stations will not be replacing Regular Gasonline ( which already contains 10% Ethanol ) but will make the E15 available for those who wish to use it. By doing a quick google search I was finding the new E15 WARNING LABELS...

    LED TailGate

    If you try to connect it only to the 3rd brake light you will loose half of the functions of the bar. The 3rd brake light is just that nothing more than a brake light, but these bars are a running light, brake light and turn signals. The best thing to do is to tap into your brake lights so...

    CB Antennas

    I actually ran it thru the passanger side rear vent window. I don't use those windows much so it worked out good. Then I ran the cable under the headliner until I got to the door post between the front and rear doors and ran it down behind the plastics under the seat. The mount came with...

    New Flowmaster 40 series

    Definatly the small tips tend to make the exhaust "pop" a bit, if you put on a 3" or 4" tip it will give it more room to "echo" and give that famouse Flowmaster sound. I am running a 70 series Dual 2.5" in and single 3" out Flowmaster with the rear cat delete, the factory Y pipe delete (...

    Ethanol 85 & 2000 Ford Expedition XLT

    You really don't want to do it, and it would be EXTREMLY COSTLY to even try ( fuel pump and tank have to be changed along with fuel lines, also the computer would need to be retuned to run more fuel thru the injectors) the only way to see a true benifit from E85 is if you where to convert your...

    New Flowmaster 40 series

    The Flowmasters get most of there "tone" from the tailpipe. If you cut it off it will not sound as good. The best thing to do if you are wanting it louder is due the rear cat delete ( as long as you don't have inspection, this will also free up some power on the top end but you will loose a...

    How heavy...

    They are just under 3 tons. If I remember correctly they are in the 5K - 5,500K range.
