Can oil leak from EGR valve?
Question: Why would the EGR valve leak oil? Answer: The oil may come through a seal from the actuator rod which somehow connects to the crankcase ventilation (CCV) system. This seems to be a recurrent problem on some models. You may try replacing the EGR valve and see if the problem doesn’t return.
What causes oil in EGR valve?
The causes of a high portion of oil in the intake or charge air may be malfunctions in the crankcase ventilation, worn bearings, a clogged oil return line on the turbocharger, worn valve stem seals or guides, the use of unsuitable engine oil qualities or an excessive engine oil level.
Should there be oil in EGR?
Oil in the EGR is fairly normal and I see it all the time. Don’t worry too much unless you get excessive blue smoke from the exhaust.
What happens if my 6.0L EGR cooler fails?
If this cooler fails or the coolant passages become clogged (a common occurrence on the 6.0L), it may reduce flow to the EGR cooler, or create a sludgy oil/coolant mix that won’t flow through the cooler.
How does the EGR cooler work on a diesel engine?
The cooler in your truck’s EGR system works with the EGR valve to create a mix of air, fuel, and exhaust gases that reduce emissions. These EGR coolers are a known weak point on most diesel engines, which leaves a lot of questions for owners.
What happens to the coolant when the EGR valve is closed?
Cooled when the coolant flow removes heat and the EGR valve is closed, and then heated and stressed as hot exhaust gases pass through. Each time it heats up, the metal inside the cooler grows and strains against the restraints of the unyielding metal shell, causing stress and strain.
What is the EGR cooler hose for a Ford 6.0L?
The Dorman 904-199 EGR Cooler Hose for your 2003-2007 Ford 6.0L Powerstroke is made from durable, heat-resistant silicone for a long life. Dorman’s EGR Cooler Hose securely connects the EGR cooler to the oil cooler so that coolant flows properly between the two.
