my car has a klze in it. i am having trouble with an oil leak in the left rear (passenger side) of the engine bay. i cant tell where it is coming from. it only leaks when the car is running and has warmed up. it stops as soon as the engine is shut off. also, after a while it eventually starts to drip onto the exhuast piping in the vicinity of a funny s bend and begins to smoke. i cant see it from above because of a black plastic housing or below because the oil is coming down. i did some researching and i thought it was the oil pressure sending unit. but, unless I misinterpreted it or the thread is mistaken the position of the unit is in the front of the engine bay close to the oil filter. does anyone i have an idea of where it is coming from? i hope i have given enough info.
