New to forum and not a mechanic (but handy) so please bear with me...
Shop told me I need new check valve to clear code for inspection. Bought one on Amazon with gasket and before I replace have 3 questions.

1) What is a safe way to pry the part off since it seems like even after unbolting it will be "stuck" on engine.
2) Do I need to add gasket sealer or just use gasket?
3) Will the check engine light clear after time or must I get it cleared via device?

Job seems straightforward - are there any gotchas?

Thank you very much.
