The exhaust leak is not too horrible, but, enough that I need to address it soon. Only on the driver's side; (today).
I'm planning on having a lot of PB blaster on hand, torch, broken stud removers, screw/stud extractors (easy outs), ...a hammer. Maybe a few cold Budweisers
I've got a 2006 F250 5.4l. Recently Ive had an issue when I am driving, usually when the engine is at 3k+ RPMs, where the engine will lose power and the cel with blink. Usually it only takes a few seconds for the blinking to stop and the engine continues as normal. Now, I know that at least one of my exhaust manifolds are leaking.
Could it be that the engine is not receiving enough back pressure and that is causing it to lose power? I had a similar issue last year, basically the same symptoms, and it turned out that I had two cylinders misfiring. I replaced the coil packs and that fixed it. This time there are no codes referring to a cylinder misfire. There is a code for EVAP leak (I think), but I was told it was nothing to worry about.
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 Replies2003 F350 short bed 6.8L V10---On start up a slight tap sound, almost like a cranky lifter, but it is an exhaust manifold leak. At the bolts, I am not sure. This has been this way for 5 years, no better no worse. After I run about 2 to 3 minutes it seals itself. Not a hint of noise. Due to heat, something is expanding to seal it (aluminum).
At my annual PA. State Safety Inspection the Tech says 'that has to be corrected if it worsens', but It does not fail inspection. This puzzles me.
How is the call made for correction. A flip of the coin, a guess and is it serious enough to fail inspection. Is this normal with the 6.8L or V10s. I know the cost involved for a fix is big league, but can it be justified. TRUCK RUNS GREAT !---
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....
View 14 RepliesI have an exhaust leak between the manifold and turbo ( in the flex part of the pipe) on my 2008 6.4 f250 would this create rough idle when at operating temp?
View 2 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 have a 2011 F350 CC long box 4x4, with a 6.2, 93,000 km on it. I periodically get a P0420. I clear it and sometimes it comes back in 10 or 20 KM and sometimes it comes back in a couple hundred km. Been doing this for about 800 KM.
Yesterday I got an exaust leak at the joint where the exaust manifold meets the pipe beside the engine. Checked close, bolts appear intact, leak is on the outboard side blowing towards the frame. Looks like a gasket or donut seal failed.
I am wondering if the catalytic converter was plugged or restrictive, would this cause the P0420 and could back pressure from a restricted catalyitic converter cause the gasket to blow?

A few days after the job was completed I noticed that the top stud on the driver's side closest to the firewall has signs of oil leaking from inside the hole. This is a hole that I had to drill and insert an 8mm Heli-coil. I was very careful on the depth of the hole I drilled. I tried removing the bolt and placing JB Weld high temperature epoxy into the hole and reinstalled the bolt. I waited over 24 hours for the epoxy to cure and then I checked for leaks. The leak re-appeared but has slowed down quite a bit. I have a USB endoscope that I will be using to inspect the inside of the hole to see if I can see where the leak is actually coming from. I am in no position to replace the head but I will do whatever it takes to get the truck back into service.
After 7 days in my garage, I finally removed/replaced all 20 manifold studs. I had to cut off all of the nuts to remove the manifolds. I was able to remove 17 out of 20 studs by using a 6 inch pipe wrench and a lot of coaxing. 3 of the studs were already snapped off inside the head. I drilled out two and was able to get them tapped for a Heli-coil. The third stud I broke a 1/8" cobalt drill bit inside and it took 4 days to get enough of the hole drilled out to get a Heli-coil inserted.
My '08 S.D. (5.4) has a cracked exhaust manifold, which I've heard is fairly common. Crappy Ford design. The local dealer has them in stock (imagine that, just like the 'non-bad' coil caps from some years ago, that they were instructed by Ford to keep at least 10 on stock at all times) for the passenger and driver's side. What are the part numbers?

View 3 RepliesBolts breaking on the exhaust manifold. If so why isn't ford doing a recall on this problem I have a F350 V10 90K miles and 3 on the top drivers side are missing not sure on the passenger side. Is this a problem with all the ford engines I have never had this problem with any other truck or car I have owned.
View 5 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 RepliesI've got the dreaded broken exhaust manifold studs on my 2004 F250 V10. I don't drive it much (just 50,000 miles in 10 years) and confess I've ignored the hissing for quite a while. Is there really a permanent fix for these broken studs? Or should I expect to be replacing broken studs every 2 or 3 years?
If there is a permanent fix what is it? Special studs? Special manifold? I want to keep this truck a long time and don't want to be replacing these studs every few years.
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.
View 10 RepliesWhats the best way to get at the driver side exhaust manifold? I have a leak and its tough to get at. Should I remove the tire and inner wheel well?
View 1 RepliesOur F-450 with 102000 miles lost both turbos also broken exhaust manifold bolts. This truck carries tools fuel tank and sometimes skid loader on trailer. Heard lots of bad things about 6.4 liter motor now first hand experience. Asked dealer if 6500.00 bill could be reduced since so close to 100000 mile warranty and was told nothing could be done. Can not afford to sell truck now also have two other Ford F-250s newest one 2012. Is there any other approach that could be taken to get some relief from this expense.
View 14 RepliesThis is right beneath the drivers side exhaust manifold. Not sure what it is but it appears to be leaking oil. Tried to tighten it and it seems snug. Can it be the gasket has gone bad for whatever it is?
Truck is 02 SD, 7.3, 4x4, with 512k miles.
Not really leaking bad but if easy enough to fix why not. It also appears to be leaking on the same side cylinder bank back near the rear of the valve cover. Need to see if I can snug that up as well.
It's right in the center of the pic. It's a bolt going into some sort of fitting housing that ties into the back portion of the block. Ignore the coolant streaks on the coolant hose. This is the oil leak in the darker center of the pic.
I got a 08 ford f450 sd in the shop with a cracked abd broken bolt in the driver's side exhaust manifold, any tips tricks on getting it out,I have everything loose but I can't for the life of me get the egr cooler out of the way to access the top bolts to the manifold so I can replace the manifold, or a link to a service manual would be great.
View 3 Repliesi have a 2002 250 with the 7.3. i put a mbrp aluminized 4in turbo back with a FTE 30in resonator. I'm getting a lot of noise in the cab sounds like its where the turbo goes into the 4in pipe. the muffler guy said its because of the bigger pipe and not a leak. is there anything i can do to get rid of the excess noise.
View 8 RepliesI have been smelling raw exhaust in the cab, especially when the weather is colder and when standing still.
I took it to the dealer and in the process of fixing minor coolant and oil leaks on the turbo, they located a small exhaust leak with visible soot on the back side of the turbo.
They tell me that there is no way to repair it and that only Ford can rebuild or repair these turbos.
