Question about 1986 Volvo 740
I started leaking oil from the oil cap and I replaced the oil cap but it is still leaking oil from the cap. It is not sealing properly even with the new cap and I need to know if there is a gasket that goes on the head between the engine and the oil cap seal?
The problem is there is to much crank case pressure, make sure the PCV ( positive crankcase ventalation) valve is working correctly.
