i am currently using the valve cover vent as my turbo oil return is this okay? i also notice that the valve cover is under vacuum which actually pulls the oil in the drain line i realized that when i opened the oil fill cap to check if there was pressure inside but was the complete opposite once i released the cap there was a little surge of air that you could hear being sucked into the valve cover. and within a few minutes of removing the oil cap and leaving it off while the engine was running its would cause the turbo seals to leak because there was no longer a vacuum (i know this because i can watch the exhaust blade inside the turbo) I'm really curious as to wether or not i am potentially damaging things. PLEASE HELP ?

included pic of exhaust piping from underneath finished earlier today not pretty but who cares

Moving this thread to the Lexus GD forum so members there can help you out as well. BTW, I'll leave a redirect in the intro forum so people can navigate to the master thread's new location. :thumbsup:

BTW, welcome to the forums! :hi:
