EGR delete problems

I do have a general question. I just bought a 2004 Silverado HD Duramax, I did the EGR delete on it. I noticed the difference immediately, but now I have oil coming out of my tailpipe. turbo seems to be working fine. I am thinking clogged drain or oil seal went out do to the extra pressure. Any thoughts?

I don’t believe that the two would be related in any way.

Pull the intake off of the turbo and check for endplay, side to side, up/down movement. Spin the shaft by hand. Also look for any signs of the compressor wheel contacting the housing.

After that you have to start digging deeper.
