An exhaust leak may be heard as an audible hissing or tapping sound coming from the front of the vehicle. This study focuses on the poisoning effect of coolant on the performance of a DOC + CSF system. The cause was the rear elbow at the cooler had worked it's way out of the housing which caused the problem. The only way I have ever seen an EGR cooler fail is it blew coolant into the intake and it did so pretty suddenly and pretty bad, like a Batman smoke screen bad. In some cases, coolant may enter the exhaust manifold. The repair cost would be over $2300 where about $1600 was for the EGR cooler. One of the main reasons the EGR coolers can fail on the Powerstroke is due to the engine oil cooler failure, which restricts coolant flow through the EGR cooler and causes the cooler to overheat and crack, always replace the engine oil cooler when replacing a failed EGR cooler. While the circular tube EGR cooler used on '03 engines proved more reliable (right), eventually all of them will plug up from soot, carbon, and oil vapor deposits. Mechanics can look for other causes by using a vacuum gauge to check for sufficient vacuum supply. M ost often utilised in diesel internal combustion engines, the Exhaust Gas Recirculation (EGR) system, when operating correctly, allows via the recirculation of exhaust gasses a reduction in nitrogen oxide (NO x ) emissions. 4L Powerstroke Ford designed the EGR and oil cooler systems so that the EGR cooler is unaffected if the oil cooler clogs. EGR that fails to ever come on can cause higher than normal combustion chamber temps, which as cousincletis said, can cause pinging. If left open, the excess vacuum will cause the engine to act like it wants to stall, idling roughly or surging. The valve may stick open or closed. This work deals with investigation of failure causes and to provide feasible. including both charge air coolers and the external coolant piping at the rear of the engine. By Steve Temple. If the EGR cooler splits, coolant will leak and this loss of coolant may cause the engine to overheat and head gasket failure. The header tank has been changed (this has the sensors that cause the light to come on apparently). There is no "pressure" in the exhaust of the EGR cooler that would overcome the pressure in the cooling system, just enough pressure to overcome any positive pressure in the intake. The extended warranty covered the high-pressure oil pump, cylinder heads, head gasket, EGR valve, EGR cooler and oil cooler, all components prone to high failure rates on these engines. Both cracked on the outside and spewing coolant on the outside of the engine. To check for this, look for white smoke or steam at the exhaust.

Older cars to have a vacuum controlled EGR valve, and these are often much cheaper than the new electronic valves. Injector “blow-by” can be the cause of some of the following symptoms. The one I see the most is the passageway from the exhaust to the intake is becoming clogged with carbon deposits. Turbocharger over-speed is likely the main problem and usually is intensified by aftermarket performance enhancements. Root Cause Failure Analysis Diesel fuel has been identified by at least one OEM as a Root Cause of Engine Fuel System (pump and injector), EGR, EGR Cooler, Sensor, and Turbocharger failures. The EGR valve’s purpose is to open and close (normally electronically) at certain moments during different the rev ranges, but these valves get clogged up with carbon deposits, which can make them fail, or even get blocked making them stuck altogether either open or closed. EGR coolers are used to cool the exhaust gases before they enter the intake to reduce combustion temperatures which reduce the creation of oxides of nitrogen (NOx). 2004+ EGR coolers are more prone to failure. To eliminate the chance of a cracked cooler filling the intake tube take the fitting out of the bottom of the intake install a expandable freeze plug and cut the bend off. A faulty EGR  can result in excessive carbon/soot at the turbine end of the turbo charger.
