I'm adding an aftermarket intake to my 04' 5.4 & noticed on the bottom of my intake there was maybe 10 small drilled holes, ((1/8") in diameter. Are these holes OEM from the factory, & what is there purpose? Seems to me that the holes would suck in "some" hot air from the engine bay, yet it's main sourse of air is from the inside of the driver's side inner fender well.
View 6 RepliesI am finding that after a heavy rain that water is running out of the bottom of all four door drain holes when I open them.I have not noticed this on any other of my previous vehicles.Is it "a" good that they are draining well, or "b" bad that water is getting in in the first place?
View 11 RepliesGot my car over the weekend and didn't drive until today as I was waiting for the insurance paperwork to clear. Opened my door this morning to find a nice stream of water coming out of a hole (drainage?) at the bottom of the door. It was a good amount of water that came out, and I could hear water in the door when I closed the door.
Opened all the other 3 doors and had a nice puddles of water next to each door. It was raining here Monday and Tuesday. Is there supposed to be that much water just sitting in the car after a rain? I feel like I've never seen that much water come out of a car's cervices a day after rain.

2004 4.6 V8 Trition ,two wheel drive, STX Pickup. By removing the bottom radiator hose, will that allow all engine coolant to be drained from engine? If not, about how much coolant will remain in the engine in terms of quarts or percentage of total vehicle coolant capacity?
View 1 RepliesLooking for any pictures or directions on replacing the intake manifold on the 2004 F150, 5.4. Got all the parts with the pulgs, and ignition coils.
View 6 RepliesI recently bought a 2005 F150 King Ranch. I had a 900km drive to get it home but only mad it half way and am now stuck. I was stalling every time I came to a stop and eventually lost oil pressure. This is when I stopped driving and took it in. The shop said it had a knock in the lower end and stopped diagnosing it there. I can now sell it for parts and take a big hit or I can try and patch it myself.
I am assuming based on my symptoms it is a spun rod/main/thrust bearing. The mechanic was not very supportive to narrow it down to anything other than replace the motor.
How many km might I get out of this engine if I pull the motor and replace only the crank and rod/main/thrust bearings. This will not be my daily driver so if I can get another 50000-100000 km off of that, then it will last me at least 5 years.
This is of course assuming that when pull it apart I do not find an other major problems such as bent or broken pistons and rods or scoured cylinder walls. I am not that experienced of a mechanic, so I am not that confident about pulling the heads off and rebuilding the whole thing.
I currently have a S&B Intake on my 2006 f150, 5.4. I am selling my pickup and getting an 08 with the 5.4 and am in the fortunate situation to be able to have both vehicles with me currently. Question, would i be able to swap the intakes? Place the stock intake form the 08 on the 06 and the S&B fit the 08? I know the pickups are nearly identical, but just want a little clarification.
View 2 RepliesWhistle thru intake. I have a f150 2005 with a 5.4 and it likes to whistle when cold weather when I press the gas it goes away until it idles down?
View 11 RepliesI have a 2006 F150 screw 4.6 auto 116k miles that has evidence of a small coolant leak where the intake manifold joins the head. This is on the drivers side directly under the thermostat housing. The t-stat housing is dry and the hoses all appear dry. It's just wet right at the gasket where the manifold joins the head. Reservoir is still normal so it's not leaking too much just yet.
I searched this site and youtube but didn't find any other posts. Lots of problems with older trucks with composite manifolds but nothing for this one. It looks like a part of the bottom of the manifold is plastic but the entire top and where it is leaking is all aluminum.
It seems odd that this would start in the winter time just driving back and forth to work (no load). And, yes the antifreeze is good. Just wondering if this is a known issue with this truck. Is it just a matter of replacing the gaskets or is there some other flaw I should be concerned about?
I put in a cold air intake in my 05 5.4l. Now truck will start up then die, the throttle doesnt seem to open up when i step on the gas. everything was working fine before I started on it.
View 4 RepliesI have a factory plastic bedliner in my 05 F150 with the 8ft bed. The tie downs in the front of the bed have a small gap that allows water to leak under the bedliner. I have tried using silicone caulk around the seam but the flexing of the liner makes it come unglued.
How to keep the water from getting under? The water that makes its way through the seam drains out of the factory holes in the front of the bed but I still worry about the moisture under there causing rust.
I have a switch under the dash that Im not quite sure what it does. I have an 07 XLT supercrew. Has the factory alarm I imagine. My brother has the same year, but no switch. Doesn't seem to do anything, tried to trace wires, the seem to join up with some other wires under neath the steering console area.

Long story short, I have a small vacuum leak in the 4wd system. I disconnected the lines going to the hubs to prevent grinding them to pieces as they are brand new. This, of course lock the front hubs in and disengages the X-fer case in 2wd.
It is not engaging in 4wd unless I select it, so I don't imagine it hurting anything in the X-fer case or anything. Other than the extra rolling mass, is this okay to operate at until I resolve my vacuum issue, provided I close all openings and places for trash to get in?
2004 F150 XLT 4X4, 5.4, 142,000 miles... Plugs had been changed at around 75,000 miles... Shell gas used 99% of the time.
Shudders and jerks going up inclines (big or small). Bad gas is being reported at all the local stations...Started using Sea foam and Lucas fuel line cleaner/ethanol treatment. After three tanks of that, I ran tank down till low fuel came on, kept driving, and no more shudders/jerks and ran great while low fuel light was on.
OK...decided to fill tank with Non ethanol gas this time (not Shell gas), added Sea foam and Lucas fuel line cleaner, and shakes, shudders and jerks all the time now.
Before no check engine lights came on but for once when I romped on the pedal once to blow it out, but it went off once I let off. Today going to work, entering traffic, engine light came on, blinked and stayed on. Truck now shudders and jerks all the time when I give it gas, and can only drive like Paw Paw to keep if from doing that.
Local shop ran test and #7 cylinder is not firing and two lean fuel notices. It will be Tuesday before they can check and if needed, replace coil on #7 cylinder.
I'm thinking of installing a new Fuel Pump Control Modulator as per a thread I read here, but only after they check/replace the coil. AND ALSO...turning the OD off did stop the shutters/jerks.
Noticed a small whine coming from the A/C compressor? I caught ear of it the other morning when I was putting the trash on the street and the truck was running. It's definitely the A/C because when you cut it off the noise goes away.
View 2 RepliesH2 weeks ago I bought a new Prius II and after giving my car a new wash this weekend I noticed small water marks on the bottom hatchback window. After trying to wipe them off with a microfiber cloth, they were still there. Then I tried Windex but they didn't go away. The only way I could get the water stains out was to scratch them off with my finger nail.
None of my other windows has this problem.
how the bottom of the radiator of a 2008 Rx400h is attached? I have the radiator all disassembled except for whatever is holding its bottom to the car. I have a detailed pdf of how to remove a 2006's radiator, but the method of mounting shown for that year doesn't match my 2008.
View 1 RepliesOK so I noticed the last few weeks that I have just a small shutter coming from my rear end every now and then. It feels like it locks up for just a sec and then is fine. It will normally do this earlier in the day and maybe once or twice. Is this telling me its time to add some more friction modifier into the rear diff or do I have another issue. I don't notice it once the truck is warmed up and been driving around some.

I was warming up my wife's 07 Expy the other day. Yes, I know this is the F150 forum but it's essentially the same drive train and there are more users in this forum. So anyway, it was a cold day so I started the truck to let it warm up for 10 minutes. When we went to leave I could smell anti freeze in the truck. The truck wasn't over heating, there were no puddles underneath it. I opened the hood and there was no obvious leak anywhere. The only thing I noticed was a spritz of droplets all over the intake cover and other black surfaces were it stood out. It was as if the engine had sneezed out some anti freeze, but no visible sign of where it might have come from. It's running fine and hasn't done it again since.
View 3 RepliesTitle says it all... Starts & idles pretty good. No codes. Has decent power on mild acceleration, any time you step on it more than 1500rpm it lets out little black puffs of smoke and intake makes that popping sound and truck jerks a little...EGR delete. HPO pressure is good. Injectors are fresh as of a year ago. Valves? Lifters? Turbo?
