I have the vehicle listed above 3 s hatchback. I'm getting codes P2177 and P0455 and I have some oil in the vacuum hose going to the intake. Is this possibly the purge solenoid or PCV valve or both?

I suspect you are going to have to address both codes as I doubt the same thing is causing both.

However, if you have oil in the vacuum system then I would replace the PCV as that is the most likely causes of that. Then the P2177 may be the purge solenoid so please run through the testing below for both codes and let us know what you find.

Let us know if you have questions as well. Thanks
