The carbon chucks could clog your EGR valve, which will result in loss of power, fuel inefficiency and emission of black smoke from your exhaust.

Can you roll coal with an EGR?

The EGR (exhaust gas recirculation) valve controls the amount of exhaust gases that are recycled back to the combustion chamber to help absorb unwanted emissions from the post-combustion gases. However, in rolling coal setups, the EGR valve can be bypassed using aftermarket kits.

Is removing EGR valve illegal?

Although it is not illegal to remove the EGR from your vehicle, it is an offence under the Road vehicles (Construction and Use) Regulations (Regulation 61a(3))1 to use a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was designed to meet.
