Review on Standard Motor Products V311 Valve by Richard Jarvis

works well. but I think it should come with a new rubber gasket to put in from the engine side to prevent leaks. If it's hard or brittle, and if it is, you'll need to order a new one at the same time as this new PCV, and they're also offered at Revain. but if not, go to your local auto parts store to buy one, or online. Note: This system is a sealed system, as is your entire smog system, and it must be fully sealed, meaning it cannot leak. If it leaks, your car may fail the smog test or be in an affective state. excellent day!
