Can a car run without an exhaust manifold?

Yes. A car can run without an exhaust manifold. It will burn out the exhaust valves in the cylinders a lot faster than normal, but it can be done.


Can a 1996 Ford Taurus run without a catalytic converter where is the o2 sensor at?

Yes, the Taurus can run without the catalytic converter--it is not necessarily good for the engine, but disconnecting it will cause it to fail emissions testing. If you've seen the Honda Civics running around smoking like a factory, this is caused by no electrolytic converter. The O2 sensor could be in the exhaust pipe between the manifold and converter.


Can you start your car without the exhaust manifold?

Yes you CAN start your car w/o the exhaust manifold mounted.....However, if you do, you are VERY likely to crack a valve. Your exhaust system protects the valves from cool air contacting a hot valve.


Is an exhaust leak common on 97 Jeep Wrangler 4 cylinder?

Not any more than any other vehicle, but the weak point is where the exhaust meets the manifold. a new clamp and gasket will improve things a lot. Sometimes a crack will form in the manifold itself, this can be welded in most cases, but is hard to detect without a smoke test.


How do you remove a catalytic converter from a 1992 Chevy Truck?

You cut it off of the exhaust system and replace it with a straight piece of exhaust pipe Know that it is illegal to remove a converter without replacing it with a new one.


Where is the converter on a 1997 Ford Expedition Eddie Bauer?

The torque converter or the catalytic converter? The torque converter is inside the bellhousing that connects the engine to the transmission. The catalytic converter is inline of the exhaust pipe ahead of the muffler; it's probably the first bulge in the exhaust. Removing your catalytic converter is illegal and if your state has a vehicle inspection your car won't pass without it.


Can you drive with a cylinder misfire?

A misfire on a car with a catalytic converter will overheat and destroy the converter due to unburned fuel in the exhaust. on a car without a catalytic converter, it will still wash the cylinder with unburned fuel and break down the oil, but not do any serious damage in the short term. it is possible but not good because u can screw the rest of ur motor up it is better to fix before u drive it


Can you change your catalytic converter exhaust system on your peugeot 306 to a exhaust system without a catalytic converter?

no. the catalytic converter system is there for a reason. it is reducing the impact of emissions on the environment.yes. you can but your vehicle may not pass emission standards in your state check before you remove it.


Why does a muffler have two tail pipes from one muffler?

A cheaper option for dual exhaust without making it a true dual exhaust from the exhaust manifold/headers. Not much performance gained just appearance.


Where is the oxygen sensor on a 1995 Chevy Cavalier?

Look under the hood, the front of the engine, on the exhaust manifold. It should be the only thing with wire/s on the manifold. You will need a special socket to remove it. The tool is available to "Borrow" from the folks at AutoZone. If you need any further info, just gimme a shout. Actually it depends on the engine. The 2.3/2.4 has the exhaust manifold on the back side of the engine - between the engine and firewall. You'll most likely have to get under the car to remove the O2 sensor. On the 2.2 the exhaust manifold is on the "front" of the engine between the engine and the front crossmember. You should be able to get to this O2 sensor without getting under the car (note I said *should*). Either way they're located on the exhaust manifold, before the catalytic converter.


How do you replace the oxygen sensor on a 1999 Oldsmobile Intrigue 3.5?

It screws into the exhaust near the manifold. I haven't had to change mine on my intrigue, but if it's like others I've had to change, you get to it under the car behind the engine. Follow the exhaust from the catalytic converter up to the manifold, it should be the only sensor with a wire coming out of it that is screwed into the exhaust pipe. Unplug it from the wire harness, then unscrew it using a flat wrench. Have a new one ready to install, you can't run the car without it. Hope this helps.


Where is right upstream 02 sensor Dodge Dakota 3.9L?

The right side one is the passenger side one. Upstream means that it's on the engine side of the catalytic converter. Follow the exhaust pipe down from the passenger side exhaust manifold until you get to what looks a little like a spark plug screwed into the exhaust pipe with two wires attached. That's your upstream, right side O2 sensor. If you get to the catalytic converter without finding it, you've either missed it, or there isn't one equipped.


On a 1996 Nissan Maxima which O2 sensor is Bank 2 Sensor 1 since there are three sensors?

Bank 1 Sensor 1: Located on rear exhaust manifold pipe nearest the firewall. Fairly easy to remove with the right tools. Clip located on left side of engine compartment.Bank 1 Sensor 2: Located just behind the Catalytic Converter. Very easy to remove and clips on just inside rubber gromet.Bank 2 Sensor 1: Located on front exhaust manifold pipe nearest the radiator. Hard to reach without specific tools. Clip located in front of engine compartment.Bank 1 = both front firewall-side sensor (1) AND rear sensor (2). Bank 2 = front radiator-side sensor (1). Bank one refers to the section of the manifold that vents exhaust from the cylinder bank including cylinder #1...bank two = from cylinder #2 and its comrades.


How do you make exhaust on Dodge Ram louder you already have flowmaster 40 series and a cutout and you want to make it louder Is that possible without making it too illegal?

take the catalytic converter off. you can punch the guts out of the converter so you have a pipe to got back on the exhaust.


What could cause a knocking sound on a 1995 Nissan Pathfiner when the engine hits 3000 RPMs?

If the engine knocks when it is cold, it might be a crack in the exhaust manifold, or possibly a crack in on of the exhaust manifold bolts leading to the block. The crack is small, and once warm will swell shut, thereby stopping the noise. Without repair, it might lead to valve exhaust valve damage.


Is a catalytic converter needed in a 1995 Saturn?

Yes. According to Federal law, catalytic converters must be maintained for all vehicles on which the converters were originally installed. The catalytic converters burn any fuel that was not completely burned in the combustion cylinder, making the exhaust considerably cleaner. Removing the catalytic converter is a violation of the law, and while your vehicle can operate quite well without the catalytic converter, you do not want to pay that fine.


When your driver side of the engine is smoking what do it means?

It's difficult to say, without seeing where under the hood it's coming from. You could have a bad exhaust manifold gasket, leaking exhaust. You could have valve cover gaskets leaking or seeping oil, which would drain onto the hot exhaust manifold, and burn off... If you can provide more information on where the smoke is coming from, there may be a better answer.


Where is internal antifreeze leak getting into exhaust skystem in a 3800 engine?

A gm 3.8 l v6 or 3800 cc engine cannot have antifreeze in exhaust without first getting into the engine. If its getting into the exhaust it may be entering the cumbustion chambers through a damaged cylinder head or head gasket. Also this engine depending on the model year may have issues with the intake manifold gasket, that can cause antifreeze to leak into the engine oil.


Does the 2013 crv have a timing belt?

Short answer timing belt... Long answer The lightweight pressure-cast aluminum cylinder head's exhaust ports are on its front side (vs. the previous engine's back-side ports) so the close-coupled catalytic converter can mount directly to the head without a separate exhaust manifold. The dual overhead cams (with improved journal finish to reduce friction) and four valves per cylinder are driven by a silent chain with a friction-reducing double-arm tensioner. A pair of chain-driven counter-rotating shafts in the oil pan take care of the second-order harmonic vibrations common to I-4 engines.


Where is the catalytic converter on 1985 van?

It'll be mounted to the exhaust pipe at some point underneath the vehicle. That's about as good of an answer as can be given without the make and model.


How does an exhaust manifold crack on a 2004 Mazda 6 station wagon?

I'm under the hood of mine right now and have found the exhaust manifold and the pre cat have separated. I've purchased a set of stainless headers as the Mazda cost of a new manifold was $1100.00 CAN$ That was without installation. Headers were $400 with all the piping. You'll have no more precat and one cat con will be missing but I won't cave to the dealer.


Where is the PCV valve located on a 1996 Ford Contour?

I believe its behind the exhaust manifold. You can see it looking up from underneath. I haven't changed mine yet. Anyone know if its possible to change without removing the manifold? Seems unlikely.


What is an exhaust flex joint on a car?

Some (front wheel drive) cars have a flexible piece of pipe that connects the exhaust manifold to rest of the exhaust system. The length of pipe is designed to allow the engine to rock back and forth on its mounts. Without the flex joint, the movement of the engine would damage the rest of the exhaust system.


How do you change the cylinder head cover gasket without removing the aluminum inlet manifold peugeot 206 1.9d DW8 engine?

it does not need to be removed.


You have a 1993 Mercury Cougar 38 Can you change the head gaskets without removing the manifold?

theres no way you can change the head gaskets without taking off the intake manifold, its not hard to do. plus if your going to change the head gaskets it would only be smart to change the intake gaskets also.Answerand if your talking about the exhaust manifold, you did'NT specify, I'm sure you can but it will be no fun at all, plus u should change exhaust gaskets if your going to do all that work anyways so you don't have to worry about them down the road.
