Lexus GX 2004-09 :: Exhaust Manifold Has Been Really Loud At Startup

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.

Ford F-150 (2004-2008) :: Passenger Side Exhaust Manifold Was Leaking

2005 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...

Ford F-150 (2004-2008) :: Manifold Exhaust Leak - Rusted Bolts

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..

Ford F-150 (2004-2008) :: Exhaust Manifold Leak On Passenger Side

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?

Ford Exhaust System :: Exhaust Manifold Leaking / Louder Than Normal Knock When Accelerating

Leaking 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.

Ford Exhaust System :: Exhaust Leak At Manifold Where Donut Gasket Meets The Catalytic Converters

My 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....

Ford F-150 - 1997-2003 :: Exhaust Leak On Passenger Side / Broken Exhaust Manifold Bolts

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?

Prius (2004-09) :: 2006 - Check Engine Light - P0420 Code / Air Leak In Exhaust

So today my CEL came on. I immediately looked at my mileage and I was EXACTLY at 500m past my oil change the other day. I checked the dip stick and lo and behold, it was about 3/4" past the full marker. I took it back to the oil change place and had them drain it down to a good level.

I had driven from NH to NY this week. I filled up my gas tank on my way home from NY. Gas cap was on nice and tight for sure.

The code is still on (not sure how many miles or drive cycles is required) for something to clear. I figured it was perhaps due to too much oil added. I decided a few hours later to take it to AutoZone and grab the diagnostic code. It's a P0420 code (Cat System efficiency below threshold: Air leak in exhaust before rear HO2S, AF Sensor Error, Fuel System Fault, Faulty Catalytic Converter).

Ford 6.0L Power Stroke Diesel :: 2004 F350 - Left Hand Exhaust Manifold Replacement

Attempting 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.

Ford Exhaust :: Running With No Exhaust Manifold

So I needed to replace my exhaust manifold gaskets and bolts and I didn't get the project finished in time. I have school today and have to drive my truck there and it is maybe 2 miles at the most from my house. Is it ok to drive that far with them open? I will finish putting the gaskets on today when i get home and then close them again.

Prius (2010-12) :: Check Hybrid System After Intake Manifold / EGR Pipe Cleaning

I undertook this maintenance as a preventive measure, and to see if I could bump up the gas mileage a bit. After reassembly, when I try to start it up, the engine runs for 1-2 seconds, and stops, and I get a "Check Hybrid System" error. The engine will not restart. I'm trying to figure out where I screwed things up. Right now I might have to get it towed to a shop.

I bought the Prius used last month, and it's at 151K miles. I've driven it about 800 miles since I've owned it. It had been running perfectly fine, with no check engine lights or symptoms. The scheduled maintenance items were all caught up. I had spark plugs changed, engine coolant changed, transaxle fluid changed at the famous Luscious Garage several week ago, and they said the car was in good shape. They actually recommended NOT cleaning the EGR pipe/manifold/throttle body or replacing the PCV valve if there were no symptoms or check engine lights. They said not to worry about it until symptoms occur - probably to save money. Maybe I should have listened to them, but I liked the ideal of things running perfectly.

I used information from the "missing under light throttle" and other intake manifold cleaning threads and a couple pdfs on throttle body removal and intake manifold removal from the 2010 Toyota Prius Repair Manual that Mendel Leisk had attached to another thread. I generally followed the repair manual, except for not disconnecting stuff that didn't have to be disconnected, like the coolant hoses on the throttle body. That is to say, with the manual pdfs in front of me, I'm pretty sure I didn't forget to reconnect any connectors or hoses when reassembling.

A moderate amount of dry, sooty carbon material was in the EGR pipe. I cleaned that out. The port leading to the EGR valve assembly was also filled with that dry soot, and I cleaned that out with a pipe cleaner, used dry, since I didn't want to create a sticky clog in the valve. I stuck a vacuum cleaner to that port afterwards, in case I had pushed soot back towards the valve with the pipe cleaner.

Camry :: Exhaust Leaks On Driver Side Of Gen 5 V6?

My wife's 06 v6 all of a sudden developed an exhaust leak. It sounds like it's on the drivers side right about the side of the engine or at the firewall. It's my wife's car so anything is possible, I'm wondering if there is a Y near there and she bottomed out on something. I'll be putting it up on a rack soon, where to look?
