Silicone where???

no need to replace fuel line. The seal is bad and leaking oil. happens very often. 19mm regular wrench may work on cyl#4 . You will need small o-ring that goes on injector. Valve cover must be taken off and you may need new valve cover gasket. I would replace all 6 of them. usually when one starts leaking all others will leak when winter come...

Intothesunset and PE_T Thank this. -
do not use silicone there. When you install new seal check to see TOP writing on seal is up. Also first you need to install and torque fuel line and then two 10mm bolts of seal.Intothesunset, wtokhi and PE_T Thank this.
