Some thoughts about eliminating AIR, EGR & oil cooler.

The AIR injects fresh air into the exhaust stream. The the O2 sensor sees that and send a signal to the engine computer. Thus the AIR is important to the state of tune. Note, the O2 sensor only sees the exhaust gasses from the left bank. Look closely where the "Y" pipe joins.

The EGR valve introduces exhaust gases into the fuel mixture to cool the combustion process to help control NOX. On the EGR valve is a feed back potentiometer that signals the engine computer to increases timing proportional to the EGR valves position. Thus controlling the state of tune. I have seen reports that indicate there is no loss of power or fuel mileage with EGR that has a feed back potentiometer.

In my many years on RV forums I have not seen a report of engine oil cooler failure on F53 460s.
I have see 2 reports of engine oil cooler failure on 460Ford.com. on modified PUs.

Thanks Richard,

There’s a fellow living in Austin who reached out to me via PM about some of my questions regarding the AIR and EGR systems. I’m going to call him later on. I guess my main concern is having things that are non-essential to the engines running break and cause future problems for me. I do 95% of my own repairs and have for years. The last thing I need is to have to crawl under my RV along the interstate trying to fix some non-essential item that’s caused a breakdown. Things such as a seized bearing in the air pump which would snap the serpentine belt and temporarily take out the water pump and alternator too. I’d really like to get rid of potential problems like that. Having a less cluttered engine compartment would be great too. I look at the top of my engine with all the clutter and it's like looking at some engineers idea of a bad sick joke.
