Frequently Asked Questions

Q: Does this kit require any special tools to install? A: Installation typically requires removing the valve cover and carefully prying out the old membrane; a small pick tool may be helpful but no special equipment is mandatory.

Q: Will a failed membrane cause a check engine light? A: Yes, a torn PCV membrane often triggers lean mixture or system too lean codes (P0171, P0174) and can also cause noticeable oil consumption or smoke from the exhaust.
