PCV. Slowly bringing this old girl back to life, currently dealing with lean codes bank 1 and 2. I’m pretty sure it’s a vacuum leak ltft gets better when i rev. Smoke tested today but couldn’t find a single leak. I took the PCV off and I can blow through it in both directions. Can someone please tell me if this is correct? Thoughts are the Pcv will give me a lean but won’t give me a leak test.
This is my last code to conquer so any help will be appreciated![Grinning face :grinning: 😀](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f600.png)
