2008 5.4 egr?
Hey guys I have an 2008 250 with a 5.4 and am wondering if it has an egr sytem for the motor. I notice that the oil stays pretty clean longer than my other cars and truck that I have. I'm thinking maybe no egr?

Well it must not be much, the oil stays clean for a long time, they should have done that long ago. In my opinion it is just stupid to pump exaust back into the engine, there has to be a better way to reduce emissions.

I would have to respectfully disagree with you, you introduce exhaust back into the engine and the oil gets very dirty from the carbon. On one of my molder engines I just had the motor rebuilt and the oil was getting dirty quickly. Turns out the egr opening on the manifold had the wrong gasket and had stuck the valve open from the carbon. I don't see how that could increase mileage either but I am not an engineer and could be wrong. Thanks for the info though.

It increases mileage by decreasing the engine's efficiency and forcing you to use more throttle to maintain the same speed. This eliminates some of the pumping loss of the engine.

I agree about it not having an effect on oil. Although, you are re-using dirty exhaust, it could increase the amount of carbon in the oil if the vehicle is consistently driven under light or no-load. This is just my thought on the subject.....

I have to disagree. I have a '99 with egr. I installed headers that have no egr bung therefore, have removed the egr plumbing until I can find a place that will bend me some small pipe. My tuner has allowed me to turn egr switching off and I have noticed no change in mileage. It even passed emissions last year with no change in PPM of any emitted exhaust gas in comparison to the prior year with EGR. It may have a marginal fuel economy effect on smaller cars/engines but when it comes to my V10, there is no difference. I don't know how this would effect a 5.4 at all.

If there was a reliable way to add EGR to my '05-I would based strictly on past experience with fuel economy improvements using EGR flow to decrease pumping loss at low load. If you eliminate EGR, you hurt economy-unless the system was not functioning properly to begin with.

There is a device on the 5.4 called the EGR module. Can anyone expound on that?
