Ford F-150 - 1997-2003 :: Exhaust Manifold Studs Missing - Engine Noise?
Nov 29, 2016
I was looking at my exhaust manifold..and I found a couple of studs missing...so if I want to replace both of them , is it better if I replace all of them on both sides of the engine ?
By the way..my exhaust manifold is good I don't think none of the studs are broken.. but I have been having this engine knocking noise on my engine, do yall think a couple of studs could be the problem of why my engine is knocking?

I have a 2000 with a 5.4 and 166K miles. It had multiple exhaust manifold studs broken on both sides. Now that thay is fixed, I am getting the p1131 and p1151 codes. The EGR tube was also replaced at the time of the manifold fix. I checked over all the tubes and electrical connectors to rule out something simple but did not find anything out of place. The intake manifold was replaced with a new Napa one less than 5K miles ago as well.
Could the leaky exhaust manifolds over time set the fuel trim level high and now that they are fixed, the ECM is thinking it is running too rich? Can the ECM be reset to zero? There is also a ticking/rattling noise when you accelerate that seems to be coming from the fuel injectors. I listened with the stethescope and they are the only things that sound like the noise I hear. Could these all be related?

2003 F150 4.6 - I'm currently replacing the passenger side manifold studs. How the heck do you get to the bottom bolts? Looks like the motor mount is in the way. There's way more room on the 5.4s...

My 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?

I am changing the passenfer side exhaust manifold on my '00 150. The bolts all came out fairly easy, sprayed them often in PB over the last 2 days, my problem is the 2nd and 3rd nuts on the bottom are under the motor mount. Do I need to remove that or is there an easier way that I'm missing.

So I think I have possible manifold leak in my exhaust and its because when the engine is super cold, and I do have a straight pipe, but it sounds like a tractor... until it warms up after few minutes, it goes away.
My exhaust manifolds are rusted to crap and stuff is falling off, paint or whatever there was on them.
Now I've looked at bunch of videos on UT to get a better understanding since everyone says the nuts and studs are hard to remove or snap.
Now my question to anyone who's done this in their garage; I've seen bunch of videos where the stud snaps flush, then he takes a nut, puts it over the hole, holds it up with needle pliers and uses a MIG to start welding it... stud to nut... then puts a wrench and off it goes.
Now, I'm not a pro welder or anything so is it possible to by accident weld the stud, nut into the head and then never ever be able to undo or take either one out?? or is the head or whatever made from different material that won't get welded to the nut or the stud??

I 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.

2003 F150 5.4 4x4 supercrew ,76k miles
Recently the passenger side exhaust manifold cracked on my truck. I bought this truck about two years ago with 58k on it and currently have 76k miles. I remember getting the carfax report and being relieved to see that it had exhaust manifold replaced in July of 2014 at 49K miles along with a new EGR tube. I called the shop that worked on the truck to see if he could confirm that both manifolds were replaced since carfax only said manifold & egr tube. The shop manager confirmed that both manifolds were replaced and he told me that they were most likely manifolds from napa according to the part number.
Now, my question is, what's the best brand to replace the manifolds with? Should I just go with OEM and spend the extra $130 per side? I know the manifolds are a common problem with these trucks but only lasting three years and 27K miles just seems ridiculous to me.
I'm hoping that when I get around to actually doing this that they wont be to bad because of how recently they were replaced. For now I just cleaned the area with a wire wheel and used the inferno metal repair. Seems to have done the job but I don't expect it to last long, just another month or two until I move to a place where I can actually work on my vehicles.

Truck Specs: 1997 F250 LD 184000 miles and a 5.4, automatic, shift on the fly 4x4 extended cab.
What I did: Changed the exhaust manifold gasket on the right side. There were some broken studs which came out with a stud remover.. No torch was used during this evolution.
What happened: After driving 10-15 miles it set the codes that I listed in the subject line. Reset the codes 20 or so miles later the P1131 code set again. (both times there was a noticeable loss of engine power) The upper O2 sensor checked out with a meter. When I checked the voltage on the truck's harness plug referenced to the NEG terminal on the battery, both the power and gnd had 12V- Key On Engine Not Running (KOENR).
What I did: Cleaned the connections put dielectric grease in the connections and reassembled. Reset codes; all was well ~ 100 Miles later the codes are back. I also ran a continuity check from the plug to the control module, they check out fine.

I have a 97 f350 crew cab xl stock everything. 351 windsor in it I do believe. as of right now He is broken down pulled apart in my garage. Due to a much requested headgasket replacement. In any event long story short I got him all apart to discover that there was someone in it before me & had broken the infamous exhaust manifold bolts (5) and two of the lower intake bolts, (of course I've tried the correct route in removing these broken bolts/studs but again the year of the truck (1997) & its bone stock no way their moving...
So of course I tried the next best thing (on a budget) which is to drill them out, but I went to far into the exhaust manifold bolt holes, And now I believe that I've ruined the heads is this so? If so who knows where i can get a decent set of bolt on heads ready to go. yes this is my daily driver & since He's been down I've been going deeper in dept.

I 'm looking to replace my manifold studs in my 2005 V10. Looking to replace with bolts. Would like someone who has done this to chime in with what they have had success using for bolts. Size length grade etc.

So I just installed a fresh 4.6 long-block in my '98 4x4 xlt and I have a noise coming from the manifold area. Thought it was possibly valves or timing chain. Took it to dealer and they diagnosed it as the Intake Manifold Runner Control. Never heard of it!!! Problem is, I can't find that part for this motor. Is it inside the intake? Do I have to replace the whole intake? Dealer didn't tell me, once I said I would do the work myself.

Replaced head gaskets on 2003 f-150 5.4. Now I can hear a ticking noise in middle of intake by #5 port. Maybe timing is off 1 link?

My '03 Jeep Liberty developed a quite audible hole in the exhaust system overnight (sound is coming from engine compartment) and at the same time has begun missing. The missing occurs most often in the low end of gears - once through the gears (in 4th or 5th) and at highway speeds it smooths out again. My question is are these two problems related?

Broken exhaust studs and decided to get the Banks system. I haven't run across any problems with them in the old threads. Are you happy with your headers and exhaust now that it's been on a while?

I have a99 5.4 and its missing slightly when cold mostly. I'm thinking egr poss did tune up 7 mos ago so I don't think it's plugs or coil pacs seems to get better when it warms up...

I own a e1999 Ford F350 7.3 4x4 with a Garrett GTP38R turbo. I have been having issues with very little power and pulled an CEL of P0221. I know it's for the APS and have been trying to trouble shoot it as a new APS has not fixed the problem. However, while working on that I just noticed an oil leak appear. I tracked it down and can visibly see it leaking out the top of the passenger side exhaust manifold in two places. It is seeping out the top. Is oil supposed to even be running through here like that?
I recently replaced my up pipes with the newer style bellowed ones. While I had the turbo off I replaced all the o-rings top and bottom and did the EBPV delete on the pedestal. I have been having very little power and cannot the truck over 5-10 MPH and stays at low RPM's so I originally thought it was the leaky up pipes. Those were fixed along with fuel pressure checks which came back good. I then pulled the P0221 code finally. While I had the turbo off I inspected it and it did spin freely and had no side to side play in it.
What was unusual to me was there was a small pooling of oil in the turbo when I took it off. I know the CCV goes through here so some oil is normal. Also, when I was diagnosing the up pipe leak I could see a small amount of oil spraying out the blown donut gasket along with the exhaust gases. I don't think that is normal.
Is there an internal seal in the turbo that can go bad causing oil to spill into my exhaust and possibly leak at the exhaust manifold? Or do I have an internal oil leak from somewhere else?

Just bought a 03, the seller showed me a exhaust leak. I found a bolt broken off, flush with the head. Looked at the passenger side when I got home, that side leaks too, and found one broken off bolt there too. Question, are these easy to do? As in, I have extracted broken bolts before, but they where on my V10 and I could just weld nuts to them and they came right out.

So I received my International bellowed up pipes from Riffraff and I figure I will start soaking all of the bolts with some aerokroil before I get started on monday and I see the very last bolt head near the up pipe is gone. The bolt is there but the head is gone and you can definitely see soot buildup everywhere near it. I don't know if I should order a new manifold for the passenger side and new bolts, order a driver and passenger side manifold and new bolts, or just order one set of new bolts and try to get take the passenger side manifold off and replace the one broken bolt.
