The EGR valve is an electronically controlled valve that controls the flow of exhaust gas into the intake manifold. The EGR valve fails due to carbon build up on the valve or it can fail electronically. When it goes bad, it can cause black smoke, loss of power, no start and a fluttering noise. Clean the EGR valve at every other oil change to
Product groups. A leaking EGR cooler can be the reason for loss of coolant. How exactly can leaks occur in the EGR cooler? What are the most common causes of failure? You will find out why you should check the EGR cooler first before replacing cylinder head gaskets, cylinder heads or gaskets of wet cylinder liners in this article.
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.
The EGR system recalculates exhaust back to the intake manifold to lower the oxygen content of the intake gases, thereby cooling the combustion chamber, which in turn lowers NOx emissions. This is done by opening and closing an EGR valve. The Miata's computer calls for the valve to open and close based on a number of factors.

Yes, a bad EGR (Exhaust Gas Recirculation) can potentially damage the turbo, as it can lead to excessive carbon build-up at the turbine end, causing mechanisms within the turbocharger to stick and malfunction. A faulty turbocharger can often be identified by symptoms such as a lack of power, increased exhaust smoke, excessive oil consumption, a
Here are Some Possible Causes for an EVAP Code or an EVAP Leak: Missing or loose fuel cap. Incorrect fuel cap used. Evaporative (evap) emission canister or fuel tank leaks. Evaporative (evap) emission system hose leaking. Fuel tank leaking. A small leak in any of the EVAP hoses or fuel tank hoses. A small leak in the purge valve or vent valve. 9si4. 923 111 615 104 127 490 476 65
