No, that's kind of an old wive's tale anyway! The valve material is too good now.
I believe you are asking about an EGR valve. EGR stands for "exhaust gas recirculation". This valve recirculates the exhaust gasses back through the intake in order to better burn the gasses and cause less CO2 emissions.
can exhaust manifold leak cause you to burn oil
excessive exhaust back pressure, possibly a failed catalytic converter
Yes, a prolonged exhaust leak will eventually cause problems with your cylinder head. The leaking exhaust is very hot and you can cause small cracks in the head if you don't repair the problem promptly. If you can hear the exhaust leaking, it may already be too late! Get it checked out soon!
Briggs says on a cold engine, .005 on intake & .007 on exhaust. Wider on exhaust to ensure you don't burn a valve.
Perhaps you mean EGR valve. It stands for exhaust gas reclaimer. It sends some of the exhaust back through the engine to re-burn unburned fumes for cleaner emissions.
yes
I believe you mean the "EGR" valve. Exhaust Gas Recirculation valve. It is an emissions control device. When the cylinder temperatures exceed 2500 degrees F the EGR valve will open to allow enough exhaust gas (which is inert) to cool the cylinder. This prevents the formation of NOX, which is a huge contributing factor to smog. An EGR valve takes 5 - 15% of the exhaust the exits your car. You can have troubles with this part due to the carbon build up from all the exhaust passing through it causing the valve to get stuck open or shut. EGR stands for Exhaust Gas Recirculation. EGR systems cause exhaust gas to be recirculated to the engine cylinders. Recirculating exhaust gas will reduce Nitrous Oxide emissions in diesel and gasoline engines. It does not recirculate exhaust gas in order to burn unburnt fuel. The EGR valve is the control valve which regulates the amount of EGR being recirculated. The valve is controlled form the engine management system.
geo metro had a problem with the egr valve going bad causing the # 3 exhaust valve to burn, which could cause a lack of power in the engine performance. if this exhaust valve was burnt due to a faulty egr valve the new egr valve could have gotten clogged again causing a check engine light to reappear.
If the valves were adjusted incorrectly, yes it can cause a miss. It can also burn a valve if they are adjusted too tightly.
EGR stands for exhaust gas recirculation and refers to the valve which acts as the main emissions control in a car. It helps the car burn fuel efficiently.
That's EGR valve, not ERG, and it stands for Exhaust Gas Recirculator, which is not exclusive to the Ranger by any means. All modern cars have them. Exhaust gases are sent back into the intake to burn-off remaining unburnt gases.
