[V6-12v] Razzin-frazzin' oil leak!!!!!!!!!!!!!!!!!

[The CyberPoet]

I found my leaks to be in the two EGR? hoses that came off the rear of 
the valve covers, turn 90° and enter into
the air intake system for vapor recovery. At idle, they weren't leaking 
to speak of, but at speed, the oil was spraying
around hard enough under the valves to present a significant oil loss 
through those hoses. Where the airbox at
the rear of the intake manifold seals was also awash with a bit of oil, 
indicating that oil was leaving via it as well.
I haven't checked it closely since replacing all the seals (the car 
doesn't get driven much with us being a motorcycle-centric
family these days), but the major oil loss is gone with the replacement 
of those hoses.

Good Luck!
