Egr bpt
 

I seafoamed my KA24E today and smoke was coming out of the egr bpt where the filter is on it. I am just wondering if that is a normal thing or if I have a leak. I failed the fuel evap control function on the smog test because of a leak, from my knowledge I thought they test the vapor line between the tank and the charcoal canister for a leak so I'm assuming the bpt wouldn't be the problem. I am making a homemade smoke machine to find the leak.
