ziggyfoos 1,305 Posted December 21, 2017 I believe it's the oil vent on both sides of the mid fuselage on the early model A-4s (those with the J65). Share this post Link to post Share on other sites
Tailspin Turtle 50 Posted December 21, 2017 I believe it's the oil vent on both sides of the mid fuselage on the early model A-4s (those with the J65). Correct - the oil to the rear bearing of the engine was not returned to the reservoir but simply vented overboard at a rate of about two quarts per hour. 1 Shawn M reacted to this Share this post Link to post Share on other sites
FunkyZeit 909 Posted December 21, 2017 (edited) even modern day turboprops and fans do this as well. There was a G550 parked across the ramp a few days ago and smoke was pouring out the vents at idle. Awesome video Edited December 21, 2017 by FunkyZeit Share this post Link to post Share on other sites
