| EGR deleted , what actually happens | |
Hi All , Quick question
I had my EGR deleted 6 months ago at the same time as a tune from BAS . It’s great but still trying to get to the bottom of why I have so much crud and carbon build up around the EGR cooler pipe next to the MAP sensor ?
Or is this carbon nothing to do with the EGR , just seems odd that it’s worst there. I get a tiny bit of oil in the intercooler pipes but I can’t see how this would convert to carbon BEFORE entering the engine !
When the EGR is shut off what actually happens , Does it stay open or close permanently ? Clearly I should just blank both ends and be done with it but would like to know.
Thanks https://www.instagram.com/hustynminepark/

The only remaining oil source is the crankcase ventilation. But it can also be switched off, keyword oil separator. The EGR is closed when at rest, but it can be in an undefined state due to heavy soiling. Ideally, it should be closed with a small plate.

/\ when I had mine done it was also plated to prevent any leakage through the egr.
