I have a 2006 6.0 with some more basis mods like exhaust, egr delete, and a sct tuner. After the egr delete was installed it started making a light buzzing or vibrating when you first give it power after a start. The noise is getting a little louder and now it blows bluish white smoke when it's warming up. It's slowly getting low on coolant so I have topped it off. It will make the noise after each time you turn it and only the first time it seemed to be worse in the cold.
What should I do?
Check the coolant psi?

Yea that would be a good place to start. Did you do a complete delete ?
