pcv valve replacement

[bob]

I have a 2010 Toyota corolla 1.8 engine when should I replace my pcv valve. If or when it has to be replaced is there a easey way to do it without having to taking off the intake manifold ? thanks for your help.

Hi there. Just to put a number I would say every 10,000 miles or so to check the pcv valve.
I don’t think there’s an “easy” way to change it without removing the intake manifold.
