I have a 95 4wd f250 with a 351w my manifold gaskets are leaking I was wondering if when I that the time to remove the manifolds and probably be drilling and tapping should I go with headers if I should where can I get a very cheap set I'm on a budget...
View 1 RepliesAbout to do the exhaust manifold gaskets on my 03 f250.
View 3 RepliesI 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.

View 1 RepliesThe truck we have is a 1999 Chevy Suburban 1500, 2-Wheel Drive with a 350 vortec engine. We replaced the upper and lower intake manifold gaskets with no leaks for about a week and several hundred miles then it started leaking oil and then antifreeze after that.
View 3 RepliesI have a 1999 Ford Expedition. A couple of days ago The engine started losing coolant as soon as the engine cooled. I replaced the coolant only to lose it again when the engine cooled. I was told that it is more likely the intake manifold gaskets leaking. It seems they are right. What is the cost to repair if I take it to a mechanic?
View 1 RepliesLeaking exhaust manifold? The truck has a much louder than normal "knock" when accelerating. At first I thought and had some bad fuel in the tank. I eliminated that with a full take of good fuel and some STP but the "knocking" continued. Then I thought that perhaps it wasn't firing on all cylinders but it felt like it had full power. I took it to my mechanic and he said it as a exhaust manifold leak. He said that he has never replaced the exhaust manifold but that it was a "nightmare" and expensive. He also said that it's not a safety issue but on the long run the leak would cause the truck not to pass its emission test. He said the problem was with rusted bolts that would be difficult to remove.
View 12 RepliesI have a 98 F150 4x4 Super Cab 4.6 auto that has a leaking exhaust manifold. I changed both manifolds about 3 years ago and the passenger side bank is leaking again. I haven't gotten into yet to see if its just the gasket or the manifold itself. My question is does anyone know of a set of headers I can put on the truck that will bolt up to the existing exhaust? If I make the switch to headers I don't want to have to redo the whole exhaust system.
View 3 RepliesI'm pretty sure I have a blown head gasket. I have white smoke coming out of exhaust and the oil is brownish in color indicating radiator fluid is leaking into engine. The car has over 200K on it. I purchased Steel Seal. The guy I talked to from Steel Seal said if radiator fluid is dirty (which it is)than I should flush radiator before using product. I don't have money to replace the gasket and I don't have money for a new car right now. Can this be a fix that gets me through a couple months?
View 3 Replies2005 Supercrew and my passenger side exhaust manifold was leaking. Son of a mother duck that was a joke to get removed. Front two studs broke off about 1/4" below the surface. Manifold is not cracked but putting a straight edge across it's out of plane at least a quarter inch.
Had planned on the dorman manifold but read some poor reviews about it cracking in less than a year and being warped out of the box. There is an ATP manifold with very few reviews but all good. Or just bite the bullet and do shorty headers? The driver's side looks a lot easier to access.
These trucks really weren't designed to be worked on after assembly were they? I had to invent new cuss words. Looks like Ford manifold is disco'd...
A mechanic reports a "hairline crack" in the exhaust manifold, and that things there (what things???) are all rusted and there might be problems removing manifold. Son's Internet research turns up lots of cases of Volvos with broken bolts from trying to remove rusted manifold. (Of course, you only hear about the bad ones.)
Son says he does not hear any noise (popping) and he does not smell any exhaust. Can we let it go? Is there a stickum repair we could try? (I was thinking of the high temperature cement I used on furnace flue metal duct, but I suspect it would not hold the pressure of the exhaust.)
I had a fuel starvation problem because Ford painted the inside of the fuel tank and the paint was coming off and clogging the filters and because I foolishly drove it I now have white smoke spewing out of the tail pipe and an engine miss.
I also explained that I thought that the white smoke did not smell sweet like antifreeze, but rather like diesel. (Hoping that a head gasket replacement is not required.)
I am in the middle of doing the Hutch Mod with frame-mounted Racor PS120-2 jar-type screen pre-pump filter and shortening my previous Harpoon Mod and paint stripping and powerwashing the inside of my tank. Next I plan to move on toward the engine issue.
This evening I was under the van with a flashlight and I noticed that there was a black liquid of some sort at the driver's side exhaust manifold where it joins the up-pipe. At first I was afraid to touch it fearing that it would be carbon-sooted water, but it felt and tasted like carbon-sooted diesel.
And since I haven't started the engine in two weeks and it has been routinely near or over 100F in Sacramento, water would have likely evaporated days ago.
Does it make sense if the fuel starvation problem caused an injector nozzle or its cup to crack or to stick open or to otherwise spew unburnt fuel into the exhaust manifold which would cause the white smoke? Obviously, the unburnt fuel must get from the affected cylinder(s) to the tail pipe somehow, which likely means out the exhaust valve, through the exhaust manifold to the up-pipe and through the turbo to the exhaust pipe and finally to the tail pipe.
See pictures at my CP. I can't figure out how to attach them or put them inline here because it still says I can't do attachments.
What is my next move? Remove the driver's side valve cover? If so, what should I look for, etc.?

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.
View 6 RepliesI 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)...
View 1 RepliesShould 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....
View 14 RepliesI 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.
View 2 RepliesI am about to replace the intake manifold and gaskets. I know all of that process, but first question is if there is anything i should do whilst in there. Second question; what can I do with my intake to get more power? Mainly just kind of wondering before I get my parts ordered.
View 4 RepliesI have a leak between the metal and the plastic of my water crossover.
Do I need to remove the manifold to replace the gaskets for the crossover and if so looking for a good thread showing how.
I have a 97 Expedition with the 5.4 engine and 160k miles. Recently while having other work done I was told that I had an exhaust manifold leak due to broken rusted bolts.
View 3 RepliesMy truck just started running really loud when it's cold and the leak goes away when it warms up to operating temperature.I did a little bit of investigating and I have found where the leak is coming from at the end of the exhaust manifold where the donut gasket meets the catalytic converters. It appears that the bolts rotted that hold the system together at the gasket. What should I do to repair this? I don't really want to replace the whole manifold because I know I'll break a stud off in the engine because everything is pretty rusty down there. I even took some pictures of the problem....
View 3 RepliesMy wife's 97 f150 4x4 had an exhaust leak on the passenger side. 7 out of the 8 bolts holding the manifold on are snapped off. 4 of them are snapped off 1/8" below the top of the hole on the cylinder head . I am I unable to get a drill in to drill these out. The other 3 I've tried welding a nut on these but they won't budge and I wring the nuts off. If I have to pull the head(something I don't want to do)can I just pull that 1 head or do I have to tear the intake and everything off?
