The bottom line is that a bad EGR valve can ruin the air and fuel mixture in the car. If the Engine Control Unit (ECU) can’t compensate for this, then it will result in performance issues. 2. Fuel Smell And Increase In Fuel Consumption. A bad EGR valve can cause the engine to use more fuel. This usually happens when the EGR valve is stuck
The 3 Most Common Cummins ISX Problems and Failures. 1. EGR Issues. As we mentioned, the EGR system was a newer addition to the ISX. Like any other engine with an EGR, the system can cause some problems. On the ISX, it most likely has to do with a leak in the EGR valve. This is a difficult problem to diagnose, but monitoring the coolant
An oil cooler’s external failure can leak out the coolant from the engine. The leak could result in anything from a small puddle to a steady stream of coolant under the vehicle. A coolant leak from a bad oil cooler can cause engine overheating problems. Get a professional to diagnose and manage the problem. Diminished Engine Performance. One The disconnection of an EGR vacuum hose affects the efficiency and stability of the engine. When it leaks, it can make the EGR valve not open, increase the emission of harmful gases and also cause overheating in the engine. Below are some of the performance problems that are caused by the disconnection of the EGR vacuum hose: It should be noted
Usually, a bad or failing EGR valve will produce any these 4 symptoms that can alert the driver of a potential issue. 1. Engine Performance Issues. Another common sign of a bad EGR valve is engine performance issues. A clogged or malfunctioning EGR valve can disrupt the vehicle’s air-fuel ratio, which can cause engine performance issues such
My observations: I don't have oil leaking from around my EGR. I do have oil leaking from the intercooler pipe connection and am finally taking it to the dealer today at 26,000 miles. I added my block plate at 15,700 miles and oil was already leaking from the intercooler pipe before the plate was added so I don't think the block plate caused The coolant cools the exhaust gases, and this part can crack. If the EGR cooler cracks, it can cause coolant to come into the exhaust pipe and drip from the tailpipe. If the water coming from the tailpipe smells sweet, it could definitely be caused by a broken EGR cooler if your car is equipped with one. 5. Defective Pistons or Rings Some of the likely causes include, Faulty injectors – stuck open. Worn piston rings or cylinder glazing. If equipped with glow plugs, could be faulty plugs or module. Remember, if you have an older engine with really low compression and bad timing or low injection pressure, you are more likely to have white smoke.

As a result, it drains the coolant in your exhaust system which brings us back to symptom 1 – white smoke. Gooey EGR valve. The best way to check if you have a bad EGR cooler is to pull your EGR valve; the EGR valve is located on top of the engine next to the engine oil filter. If you pull that valve out, it should be full of a nice dry black

1) Worn Seals or Gaskets. If your vehicle has worn out or damaged crankshaft seals or valve cover gasket, then it will likely be leaking oil. Once that happens, your engine will be losing oil whenever you’re driving. This means you will need to constantly top off the engine oil to avoid engine damage.
Check the engine light. When the fuel to air ratio is high, you will have the check engine light coming on. The engine control module controls all the sensors, and if a sensor in your car misfunctions, it will light up the check engine light on your dashboard. 2. Fuel smell from exhaust. carter said: Yes, the EGR was on prior, but when I pulled it off there was fresh oil all over the gasket (which was still stuck to the valve). The bolt was quite stubborn to remove. It felt like the threads in the head were damaged. I'll bet this resulted the valve not being properly clamped to the head.
Symptoms of a worn, clogged or faulty EGR cooler. Engine overheating: if coolant flow is restricted, the EGR cooler is unable to cool the exhaust gases. This not only allows NOx emissions to continue, it also causes overheating which can cause serious damage. Loss of coolant from the cooling system: this could be causing an internal leak in the
6.4 EGR valve Quick question, 2008 F250, 6.4. If the EGR Valve sticks/malfunctions, can this cause the truck to go into constant/frequent regens? I am asking because I am about to replace my turbo for a seal failure. The only code thrown before turbo failure was EGR flow insufficient. I want to figure out what may have caused the seal UkJ5n.
