Sorry. I hate acronyms, and then I use one.
EGR= Exhaust Gas Recirculation
I wrote EGR when I ment Crank Case Vent valve.
It is a valve , usually in a valve cover with a hose going into the intake manifold. It vents crank case blowby into the intake to burn it instead of dumping it into the atmosphere. If the check valve gets stuck closed, pressure builds up and make a leak.
