2019+ engines have this issue. My 2016 GMC Sierra has not (so far).

Any DI engine has the issue. My 2010 V6 Equinox has this issue. Fuel is introduced into the combustion chamber, air and oil vapor are the only things going through the intake. Reduce the oil vapor, reduce the build up on the backs of the valves.
