Hi All,

While working on the car this weekend (99E300TD) I noticed that the wells that my two rearmost injectors sit in were full of lube oil. Is this indicating that my ?CCV/PCV? valve has gone bad ( sorry, I'm not exactly sure what you call that little hockey puck screwed to the head cover above the ?#5? injector.
How often does this item need replacing ? The tubes going to/from it seem to be alright.


BTW: Just finished sucessfully extracting a snapped glow plug ! That sure wasn't fun, but thanks to all the excellent posters on this subject - you guys are awesome !

I'm gonna plug a guy in Wakefield, MA at Metric Screw + Tool, if that's OK. What a nice guy - he only sells metric hardware, and has all those oddball screws + stuff you can't ever seem to find. He hooked me up right.

There is no such thing as a CCV valve on diesels. Those pucks are oil separators and an o-ring or seal has failed.

Thanks for the schooling. I'll install another one asap and double check the hoses that connect up to it

Hi Again,
Does anyone know what mercedes calls these things ? I can't seem to find
a listing for them online.

Thanks

You might want to check that it isn't diesel leaking from a braided return line filling the inj well......

Hi,
Just got back online.
It's definitely not diesel - Dirty Mobil 1 for sure.
Thanks for the link
