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
So it's a 2002 SC430
The speedometer doesn't work and the ABS light is illuminated.
The VCS also doesn't respond.
We changed the 2 transmission sensors and nothing.
There are no codes.
Someone said to reset the ECS but that is beyond my skill level.
Am I missing something obvious?
