2004 Landcruiser excellent condition 77K. Exhaust manifold/heat shield type rattle, intermittant but >50%time. ONLY when in Drive and at Idle at 6000rpm. Goes away any higher rpm. NO rattle in Park or Neutral.
View 8 RepliesThe guy at the muffler place says I have a cracked exhaust manifold. He also says he can't get the parts after holiday. I'm supposed to drive, with my family for holidays. The muffler guy says that should be fine - highway driving will generate enough airflow to keep us from all dying of CO asphyxiation.
View 17 RepliesI have a 1993 Toyota Corolla 1.6L with 200K miles. It is a sweet ride, but about every 2 or 3 years, the exhaust manifold cracks. I have replaced it several times, installing new gaskets, and carefully following the torque specifications on all of the bolts, but eventually, it cracks again.
View 18 RepliesI have a question regarding a leak i have in the manifold of my toyota camry 2002 2.4 cylinder. the engine check light is coming up and after a check on the mechanic there is a leak in the manifold where the catalytic converter is attached. when you put your hands near the pipe, you can feel air coming out. See the image attached.
The link is in the part mark as X. The catalytic converter is the one which is circled. [URL] ....
When I remove my foot from the accelerator, my '86 Land Cruiser makes a noticeable and resonating vibration. It generally occurs at deceleration from about 60-65mph or when I'm going down a hill, when I habitually feather the accelerator to regulate my speed regardless of the slope, and rattles the whole truck to the extent I can feel it through the back of the driver's seat. The truck has always had a certain looseness or slop in the driveline; if I'm not careful to feather the clutch release, the truck starts off in a herky-jerky motion. Yesterday, I was nosing around under the truck attempting to discover the source of the vibration. When I grasped the rear drive shaft (it has a second drive shaft for the front wheels), there is noticeable free-play of about 5-10 degrees in the shaft rotation. Is this normal for this truck?
View 6 RepliesI drove my 2001 land cruiser into the shop after a 3 hour drive - it was making a thud noise (sometimes) when I went from stop to go. Felt like transmission. They called and said they put it on the lift and heard a thud from the transfer case, put it down, and now it cannot go in forward or reverse, just grinds. I said - I drove it in - they replied it must have just gone out when they had it.
View 1 RepliesMy Toyota land cruiser 1993 dies at low speed only turning left....ONLY leftSo, it started last year while in low turning left off road she suddenly died and I just about rolled her, but was able to turn her back on and keep going albeit in higher RPM. Now, she dies all the time when making a slow speed left turn and ONLY left turn. Also, in low she bucks and starts to die....
View 3 RepliesI have a high-mileage 1984 Toyota Landcruiser that has the 2F engine, 6-cylinder, carburated. It's also got a manual 4-speed transmission in it.
Problem 1: When I'm driving the vehicle down the road and the engine is at temp, it kills on me as soon as I push in the clutch and take the load off the engine. I'll push in the clutch and start coasting to a stop and I'll watch the tachometer go from 2500 rpms or so and drop to the idle range (900 rpm or so) and then it will just continue on down to zero as the engine kills. Fun fact: the engine doesn't do this when it's cold! Another fun fact: when I first bought the vehicle 6 months ago, it didn't do this. I had to replace the power-steering pump right away, and in replacing it, my wrench slipped and snapped a vacuum valve. I drove it with no problems with the broken valve for a week or so before this issue started. Once it DID start, I quickly fixed the valve, and the problem has continued to get worse and worse and worse ever since then.
Problem 2: Since this thing lives off an excessively complicated vacuum system, I immediately suspected issues with the vacuum lines/valves. I went over each and every one of them, replacing old, worn, and cracked lines, and 2 bad valves. I also discovered (through my handy Haynes maintenance manual for the vehicle) that I had a HUGE vacuum leak in the form of a long metal vacuum tube that runs along the engine which was rusted completely through on one end. I sealed that up with JB Weld and let it cure...and ever since I sealed up that line, the damn thing won't hardly run. It's got NO power, it backfires, coughs, spits, and barely runs.
I had a compression check done and found low-compression in cylinders 3 & 6. I also notice a tiny little bit of coolant (antifreeze) leaking down the side of the engine block from up near the head gasket, and I've also noticed lots of steam/water vapor coming out the tailpipe, even when it's up to temp. I'm beginning to think that I have a bad head-gasket. I'm also suspecting that it could be a bad fuel pump that's cutting out...but it seems a bit beyond coincidence that it's doing it every time I take the load off the engine when it's warm!
I rebuilt the carburator, changed all the filters, did numerous repairs to the vacuum lines/valves, changed the thermostat (since that's what powers the vacuum system), verified that the fuel pump is working, etc. No luck so far.
One of my exhaust manifolds has been really loud for over a year now, just at startup. Sound becomes more quiet as the engine heats up.
No lights on dash, but I do have emissions here so I'd like to get it fixed early 2016.
Curious what the shop charges for this install. Or if it's worth it to do both at once.
When the temperature dips below 30 degrees the vehicle has a tough time starting and in some cases won't start at all. It will crank and crank, it just won't fire...once the temperature starts to rise the engine will start fine and will be good for the rest of the day. We took it to a mechanic last year and spent $350 for a temperature sensor replacement which has proven not to be the issue!!!
View 3 RepliesI'm trying to chase down the cause of a P0420 code and make sure there isn't anything else causing it before I take the rather hefty financial hit of replacing the cat. Since it's the first Prius I've ever even been around when running I can't tell if its exhaust makes more noise than it should, but it has always seemed to me that it makes more noise up near the engine than it should, so I'm planning (well, 'fogging' is probably more accurate given my plan...) on smoking the intake and exhaust. The intake is fairly easy- but the exhaust, the exhaust manifold is rather buried. Do I just need to take the cowling off so I can look down at it and see if it's leaking anywhere? I'm assuming I won't be able to see it completely from just down below it...
View 3 RepliesMy 05 Gx has the infamous manifold exhaust leak on the driver side. I'm planing to change it myself I don't think it should be that tough.
View 2 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...
Truck has 107 thousand miles; had to take it in for an manifold exhaust leak. Mechanic said bolts are so rusted they break.
1) was there ever a ALERT from ford about these bolt's?
2) Thought i read ford had stainless bolts for this problem...
I've had F150's only since the mid 70's and this 04 has cost me more in repairs than ANY previous F150..
2004 SCrew, FX4, 5.4 ... I had the dreaded exhaust manifold leak on the passenger side. After reading the horror stories of this repair and living in the rust belt I decided against fixing it myself. I took it to a local repair shop to have done. Initially the mechanic could see that the front 2 studs were snapped off (before even trying to remove them).
After a full day of fighting the studs (engine loose & lifted up) everything is out but the front 2 studs. the top one has about 1/2" exposed, but it is frozen in place (penetrate on it overnight). The biggest problem is the bottom stud. it is broken off about 1/8" below the surface of the head. The guy doesnt have a small enough right angle drill to get between the frame & head to attempt to drill it out. I will gladly go buy a drill for him to do this, as it will likely save me money if it will work to drill out the stud.
Need to get the 2 studs out, particularly the bottom one, or what right angle drill may fit in there?
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 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 an 06 with a 5.4 with 70k on it and I have already had to do the exhaust manifolds twice, once covered by warrantee at 19k, then again around 40k and now at 74k I have a major leak from the left side manifold again
View 1 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?
View 1 RepliesAttempting to take this on myself. My passenger side manifold was replaced a year ago.....BTW This damn truck - all stock - no modifications of any kind - just turned 100k miles. One owner - me.
So I have removed everything I think I need to to gain reasonable access including the fenderwell and all the intake tubes and battery and coolant reservoir. I want to use some heat and try not to break the bolts but there is a thin wiring harness just above the exhaust manifold. I can't find it in any diagrams on the ford parts site. It looks like the glow plug and injector harnesses are up above near the intake manifold but this one is down below all that. It connects to small rubber thing - 1 for each cylinder. There is nothing else electrical near it - everything else is up top.
Now my rant - look away if you are a die hard ford truck fan or 6.0L powerstroke fan.
So far I've had to replace both exhaust manifolds because they burned and rusted right through. New transmission cooler lines -yes - rusted through and cooler (because we couldn't get the lines off without destroying the cooler). Cat got clogged (that was fun to find and fix). All 4 front ball joints replaced. Transmission dip stick tube rusted through. Several brake lines had to be replaced due to rust. The air conditioner quit with about 80k miles. I haven't fixed that yet. My oil pan is rusting through and needs replacement. Friggin oil pan! I have never in my long life experienced that. I know of other diesel pickups that are older with far more miles that live in the northeast, used for plowing and never garaged that don't have their oil pans rusting through. Just had to change both power steering lines that go to the gearbox due to leak caused by rusting through. EGR needs to be cleaned or replaced almost as often as the oil need changing. This POS needs to be out of my life!
Too bad because if it was dependable and wasn't made out of the cheapest crappy metal Ford could find it would be a great truck. Rides and hauls great. Plows great. Good looking truck, too. Standard cab 8 foot bed. Dark green. Just can't keep doing this.
