Do you need to replace the EGR pipe?

Even though the functioning of the EGR system may seem complicated, replacing the EGR pipe won’t be. You may need to remove various air intake parts to get at the EGR hose Then you’ll need to unbolt the EGR tube from the exhaust manifold and separate it from the EGR valve, unbolting it and disconnecting the associated vacuum hoses.

How do you remove the EGR tube from an intake manifold?

After all electrical lines have been removed, spray some penetrating oil onto the nuts and bolts that connect the EGR tube to the EGR valve and the intake manifold. This will loosen them and permit you to remove the tube without stripping the nuts or bolts. Step 6: Disconnect the EGR tube from the intake.

How do you replace an EGR gasket in a car?

Replace hoses if necessary. Remove the bolts holding the valve to the cylinder head. If you have trouble removing the bolts, spray them with WD-40 and let them sit before trying again. Remove the valve and any remaining gasket material. Avoid having debris fall into the cylinder head. Install the new EGR valve, following factory instructions.

Why is my EGR tube not working properly?

The exhaust flowing through it can leave behind residue that builds up in the tube. The high heat of these gasses may also damage the tube, causing leaks. In either case, the result will be that the EGR system doesn’t supply exhaust gasses to the engine when it’s supposed to.

How to replace an exhaust gas recirculation ( EGR ) tube?

There are usually three or four bolts that secure the engine cover to the top of the engine. Using a ratchet extension and the correct sized socket, remove the bolts and then remove the engine cover. Step 3: Remove any air filter and coolant lines as needed.

What happens if you cut the EGR valve?

Couldn’t break the bolts loose on the air pump so just letting it hang there If you have cut and plugged the exhaust tube, you can probably leave the rest of the EGR alone. The computer likely looks for the valve to move and if it sees the valve open it should be happy. With no exhaust, there will be no EGR function.

Is there an EGR belt in an 88 5.0?

Removal, Belt in an 88 5.0; “…I tried an 89.5” first, 2 inches shorter than stock and it was too long. So I went back hoping for something about 88 or so and all they had was a 87.5. It was a bit short and a royal pita to put on but it is running fine.

What causes an intercooler hose to pop off?

It is possible to have DTC P0299. Due to the closed PCV system on the 6.6 LLY engine it is normal to have oil residue in the air charge cooler hoses and pipes. The oil will migrate to the lower areas of the air charge cooler system and may cause customer concerns of oil seepage.

What kind of intercooler hose does a Jaguar X use?

This one had a split intercooler pipe, and also the turbo intake pipe rubber union had disintegrated. The solution for this car was to buy a new silicone intercooler hose, an EGR blanking plate (its something that may aswell be done when working in this area) and a 51mm to 45mm reducer pipe for the turbo intake.

How does the exhaust gas recirculation ( EGR ) system work?

The Exhaust Gas Recirculation (EGR) system takes a small amount of exhaust gas from the exhaust manifold and pushes it into the intake manifold to help reduce nitrous oxide emissions.

Is there a way to change valve stem seals?

Head gasket kits usually come with a new set of valve stem seals. You can install them yourself with one simple tool. It’s totally worth doing, old hardened seals will allow oil into the engine which will cause a blue smokey cloud at traffic lights or when restarting the engine. Easy fix, just follow my guide.

How can I Stop my stem valve from leaking?

The packing or bonnet nut can be tightened to stop a valve that is leaking when it is open. Sometimes Teflon packing rope needs to be added under the packing nut to stop the leak. Check out my other videos, bookmark this channel by subscribing, it’s free! https://www.youtube.com/channel/UCUsf…

What happens when the EGR valve fails in a car?

The EGR tube is the passage through which the vehicle’s exhaust gases travel from the exhaust back into the intake. When the EGR solenoid or valve is opened, exhaust gas is allowed through the tube, and into the engine for consumption. When the EGR tube fails or has any issues, it can cause problems with the operation of the EGR system,…

Can a cracked EGR tube cause a rough idle?

Cracked or broken EGR tubes will create an exhaust leak which can cause a rough idle. The idle may surge or stay higher and lower than normal, and may be especially noticeable after cold starts.

What does it mean when your EGR is not working?

Knocking, usually noticed as a pinging noise coming from the engine, can be another sign that the EGR system is not recirculating gasses properly. If there are problems with the EGR system, then the vehicle’s check engine light might come on.

What causes a gas leak in the EGR tube?

The EGR tube can become clogged over time. The exhaust flowing through it can leave behind residue that builds up in the tube. The high heat of these gasses may also damage the tube, causing leaks.

What can I use to clean an EGR valve?

This is a home experiment and an unbiased use of JLM Diesel Air Intake & EGR Cleaner. Similar products are available. This product is designed to dissolve carbon deposits, gum and varnish build up. It should restore air flow to the engine thus improving power and acceleration while reducing exhaust smoke.

The Exhaust Gas Recirculation (EGR) system takes a small amount of exhaust gas from the exhaust manifold and pushes it into the intake manifold to help reduce nitrous oxide emissions.

How does the EGR tube work in a car?

The EGR tube acts as the main passageway of the EGR system, directing the exhaust gasses produced by the engine’s combustion from the exhaust manifold through the system, eventually recirculating it back into the intake manifold and back into the combustion chambers and the air-fuel mix to be burned again.

What happens if you have a bad EGR valve?

When the valve is opened, exhaust gases are allowed through the vehicle’s EGR system to help control vehicle emissions. When the EGR valve has an issue, it can cause problems with the flow and operation of the EGR system, which can lead to increased emissions and performance issues. Usually, a bad or failing EGR valve will produce any these 4…
