My Engine replacement odyssey - 1994 HR
My engine replacement odyssey has begun. I posted questions about the 460 V8 in my 1994 Holiday Rambler some time back and after much engine diagnosis and finally laboratory analysis of my crankcase o...

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.
