Engine idles perfect when cold but as soon as it warms up it starts sucking a ton of air in the pcv valve and runs very rough with a weird pressure equalizing noise when shut off. No cel, no codes. Checked for vacuum leaks and found none. Anyone ever encountered anything like this?

Replaced with oe and now it runs great.

I found that the Febi brand one isn't as good as OEM. __________________ '96 318ti California Edition- Montreal blue '68 1600-2-Caribe blue | | | ![Reply](http://www.318ti.org/forum/images/buttons/reply.gif) | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
