hello to everyone,was looking around the engine to see how i can get a oil drain for my provent 150 catch can,this bung is right under the oil cooler housing,high lighted in red,haven't undo it yet,but do you think that it is an oil drain hole.
If it's above the sump it's probably oil pressure. The zd30 patrol has 2 oil pressure sensors, one of which is one the passenger side and that might be where it goes.
