There's no getting this O-ring to seal again! Must have been torn during install by previous owner. Great news in my opinion because it isn't a rocker shaft that's loosened up, and not a top side leak that requires removal of the whole fuel injection setup.

Good news, appears the primary leak is the outboard O-ring on the drainback tube!

By far side, I mean on the passenger side of the vehicle. Taking cam covers off to investigate rockers, first.

75 911S - original 2.7 engine It has been in storage for over a decade, in the process of sorting everything. Can warm up to operating temperature while parked - no leaks whatsoever regardless of revs. Drive around the block, lose a quart of oil from the far side of the engine. Not the cam covers - that interface is the only thing in the area that is dry. Maybe the cam carriers or drain tubes? (although the latter have at some point been already replaced with the expanding style) Any thoughts or experience?
