Title: EGR removal ?
Post by Nunnspoet on May 5^th, 2012, 9:00am

Hi folks. On simplelists "slade" has advised that when the EGR is removed from the 24 valve Scorpio that a vented Oil filler Cap be fitted otherwise there will be Piston blow back causing all sorts of Oily problems.

My 24 valve Estate has not suffered over at least 3 years, but if there is any adverse affect it is best to air them and get it sorted out.

The egr takes exhaust gas out of the exhaust manifold and puts it back into the inlet to burn off any left over fuel, making the gasses cleaner.

To get blow back the PCV vavle would have to be blocked off

Isn't it the cat that does that? According to the blurb on this site the EGR allows for leaner fuel mixture for steady cruising by reducing the amount of outside air going into the cylinders in proportion. (?)

The cats do most of the work but the egr does it to

EGR stands for Exhaust Gas Recirculation, it just a valve that allows exhaust gases to be sucked back into the inlet manifold to 'reburn' the exhaust gasses to burn off any left over fuel vapor.

Thats how they can make a car more effeicent.

EGR reduces the amount of Oxygen in the cylinder at certain times, which helps reduce the amount of Nitrates in the emissions, usually at cruise condition with small throttle openings.
