Can I get some long-term feedback from people who have done this modification?
1. According to "mlody" from different forums, he did all kinds of CCV mod, and eventually had to replace the pistons rings (all 3 rings), and only this (replacing the rings) solved his oil consumption problem.
2. Now onto this mod. When you look at the Duralast PCV Valve shown on the first page, it is basically a valve with spring inside, once the vacuum reaches a certain point, it opens up allowing vacuum to to suck air into the I.M.
In a way, this design is similar to the BMW stock CCV Valve (which also has a spring). Perhaps the Duralast spring has different design (different In Hg when it opens).
Can some gurus explain why the Duralast PCV valve is better than BMW spring?
- What is long-term report on oil consumption using this mod (or similar mod)?
The more I read the more I get confused.
