The car part that's almost extinct - just 8% of new models have it

Well this is about a car part that isn't actually extinct. But there is so much disinformation about EGR systems that many people are amputating this part of their vehicles.

 

Here's an entertaining look at how EGR's work.

It seems Ford have a problem with the exhaust gases burning through the water cooling wall.

The first sign is when your radiator water is turned into steam .

I liked the way he brought science into the description.

 

Plus stuff like 'everyone knows that air is 21%oxygen,  78% nitrogen &  1% gunsmoke'

 

Well, he is a mercan.

It's not that good for the Motor. Gunk's up the inlet tract and get mote Bore wear.. Just reduces N0X by making the combustion temp lower. Nev

Just like your pcv, the EGR is essential not just for emissions but proper air and oil flow in the motor.

 

Their blockage is a major source of sludged motors.

Once the sludge builds up all the tiny oilways for cams and variable timing get blocked and a dead motor is soon on the cards.

 You Mean it is the EGR . That ruins the engine ! .

Also the pcv which controls the pressure waves in the crankcase, they need to be checked and cleaned regularly and replaced asap if faulty.

 

When blocked the oil is quickly contaminated and the head is first to fail.

EGR sludges the entire intake and builds up on the underside of the valves and causes more cylinder wear and reduces power and economy. It reduces NOX.by lowering peak combustion temperature. That's all. Regular oil changes with GOOD oil keep Diesel engines very clean these days. Nev
