Thanks Mike
We re on the same page , I chopped that piece off donor car and pulled it straight out .
Yes it would seem like a vent of sorts , as the oily residue was rather thick at the 2 broken spots on w114 frame .
Im determined to clean up engine best I can and eliminate any possible leaks.
- any insight on removal of hand cranks ?
both the window and vent knobs - nothing obvious to me at first glance
- "c" clip of sorts ?
