How do i know if i have EGR on a TD42t?

So if someone asks me if i have EGR, am i correct in thinking that if my blow by is feeding back into the pre turbo intake, then i "have" EGR?

If i didnt "have" EGR then i would have either blocked it or have a catch can?
Cheers

Egr is exhaust gas recirculation. It's a duct which runs from the exhaust to the intake.
People don't remove it as its a road worthy issues to do with emitions control so they blank it off.
The blow by is a smaller rubber tube from the rocker cover which is ducted to the intake.
Many exhaust this to atmosphere threw a catch can.
The cleaner the air going in the better the bang inside..

So to see if you have a blocked egr you need to look for a thin plate inserted between the flanges for the pipe from exhaust to intake..

Hope this helps

Depending on what TD42 you have...
See this thread for the pic of where you block the EGR on a TD42Ti. From a GU.
