Ford Super Duty (1999-2016) :: F250 - Hole At The Back Of Upper Intake Manifold
Aug 3, 2013
1999 F-250 LD 5.4... There is a hole on the back of the upper intake manifold, just below the back of the throttle body, is a vacuum hose supposed to be attached here? Have a serious vacuum leak, no coolant loss, no overheating, just had cop's and spark plugs done, now she backfires, stalls and will not stay running, mech. says its an intake gasket but the gasket and lower intake manifold look new.

I needed to replace the intake manifold gasket on my 2002 f250 v10. Tore everything apart put the new gasket in which was the same as the old one lyrics to notice something isn't right. I have been driving the truck for over 10 years like this. Is it OK to just continue bolting everything down and go on like this? I am guessing the prior owner 10 plus years ago put the wrong intake on. I keep looking up intakes but they all look just like the one I have. Also that port exposed is on the back passenger side.

Wife took truck out and turned around after going less then a mile, saying it was running very bad. We got this truck about two months ago at a state vehicle auction. It was a state used truck, 145,000 miles, 05 Ford F350, ext cab and 8' bed. Anyway at first I thought it was valve tap until research said an exhaust manifold. With a fog machine in rear exhaust pipe we confirmed it was leaking and replaced the exhaust manifold. Figured it was probably a good time to replace spark plugs too. Took truck for a ride and she still buck and farted.
Got a code machine and got P0171 and P0174. Couldn't find a vacuum leak, but your could hear the air being sucked in. went to local parts store, guys couldn't find leak, but they said truck sounded like a steam machine. today I made a homemade smoke machine and smoke came from air intake, figured the gaskets were bad. The pictures show what I saw when I took the gaskets off. The port that has melted is the same port were the exhaust manifold was leaking from. Am in deep "doo-doo". What caused this?

2001 f-250 7.3 radiator. If you ever have to change the water pump think about removing the radiator first. Looks like they are paper thin and very easy to damage. Must be a problem since the local parts house carrys them in stock. Just thinking.

Need the fuel system diagram or schematic for my truck.
1999 250 superduty v-10 Ser# 1FTNF20S1XEC67940
Every time I run it I smell gas. I changed the f/p 6mo ago. While I was working on it I noticed there was a hole rubbed in a small hose. I assumed it was a return line (smelled gas before too) and when I fixed it the smell went away until lately. I dropped the tank,yesterday and didn't see any problems. Just need to find out what hoses go where so I can replace the hoses??

The truck starts up fine. then after a minute or so it starts to spit and sputter and back fire through the intake then dies.
What could cause this? Intake manifold gasket leak?
Will a clogged fuel filter cause this?

is there a set of headers for my 2008 f250 5.4 rwd that will install somewhat easily without me throwing tools across the garage? I see a lot more options for the older trucks. I have a pretty annoying exhaust manifold leak and I figure I might as well throw some headers on if im gonna be in there. I really want to go for sound rather than power. I think I saw a set by flowmaster that looked decent.

I have an 03 F250, 5.4, 4x4, with aprox. 130k miles. I recently had my exhaust manifolds replaced because 1 literally cracked in half. Ever since the replacement, I'm getting worse gas mileage! Im only getting aprox. 250 miles to a tank when before it was well over 325 (highway)...

Should I attempt to replace the passenger side manifold with what I can get from Napa. I would rather pay 100 bucks for everything and do it myself. But, Im concerned about replacing the studs. From what I have read the studs seam to be the problems for most leaks on these vehicles. I have torque equip. and other tools to do the job. Just want others opinions about this project. How hard really is it? 1999 5.4L F250 SDuty....

I have a 2004 F250 Lariat Crew Cab FX4 6-3/4' bed.
What is the procedure to remove the Driver's side Rear Sway Bar Link upper bolt? - the link attaches to the frame. The nut is on the inside of the frame with about 1/3" to 2/3" clearance between the frame and the fuel tank. Of course, the frame's "C" shape faces towards the inside.

I have a 2005 f250 5.4 no mods. its got 120k and needs a wake up. the passengers side exhaust manifold is leaking to the point of fixing and would like to get some input before the big purchase. my question is, headers or new manifold, and what brands is preferred for both I really don't prefer one or the other i just want the best fix really. Changing coil pack and getting more performance out of them and if so what brand. I would like a boost in lower end acceleration and throttle response, like a programmer or such. and if so what brand once again.

I have a leak at the driver side exhaust manifold. Its a little tough getting at it to tell if its a lose bolt, crack or bad gasket. What would be the best way to get at this area? Should i remove the tire and wheel well or is their a better way. If i can get at it i may replace the manifold all together.

So i was thinking about buying a intake manifold for my truck and porting it and polish it. Would it be worth doing. I've decided that trying to port the heads will take up to much time and money for gaskets. Now the only reason why I am buying another stock one is so i can take my time and do it right.

I have a 02 F250 V10. When I am pulling a trailer and began to travel over 50 MPH the truck feels like its moving left to right almost like its sliding on ice. Its worse the more weight I am pulling. When I am not pulling anything there is no issues. The trailers I am pulling are gooseneck trailers. What would cause this.

First tech post for my new truck. I just bought a hold-over but new 2015 F250 XL Supercab 2wd and love the simplicity of no unwanted options. That said, there are two features I am adding. The first is perfectly straightforward, cruise control (swap button cluster and have the function turned on by the dealer). The second is a tiny bit more involved, back-up camera, in mirror display with bluetooth hands-free (I like the simple AM/FM radio because I can work it all with gloves on).
So I basically need three things from the truck and my research has been inconclusive on a couple of things because most of the threads are for 2014 or earlier. I think I can pull switched 12V and ground (pin 1 and 4) plus reverse lights (center, or pin 7) all from the the trailer wiring harness. It appears these are not affected by the canbus load restrictions of other places to tap reverse signal (remember, XL so likely nothing in the overhead console for the auto-dimming rear view mirror). Are there any challenges with this when I do hook up my enclosed trailer or when it is not hooked up regarding the trailer brake controller/anti-sway?
I already found a good youtube video for how to route the wires so I think this is my primary challenge at this point.

I bought my first vehicle last October, a '99 F-250 with a 6.8 V10. I later found out (AFTER hauling a big load of rocks in a dump trailer) that one of the bottom leaf springs was broken. So this winter I have been thinking on what I want to do about it when it warms up. This is pretty much on top of the "to do" list for my truck. I did make a thread about putting 1 ton springs under it, but I think I'll just stick with the regular 3/4 ton springs. So now this is where I have another question, and I think this pic will tell some of it:
Now I'm not sure if those rear springs are stock, but that rear end is way the heck up there! The truck itself is not level, the front looks to be correct height, but not the back. A buddy at school and I were talking about a leveling kit for the front. But the more I look at it, I think the rear end should come down. I don't want to get bigger tires, as I just put brand new Transforce AT's on the back and plan to put new ones on the front in the near future.
Another question of mine is, would this have been a truck ordered just for pulling a camper? It has holes for a fifth wheel hitch in the bed, the rear end sits high, and it didn't come with a tow package. The PO told me that he put the receiver hitch on it. I'm fixing up stuff on it one thing at a time. Springs just happen to be next on the list.
