Hey guys I pulled my 3,8L engine out recently to solve oil leak under the cylinder head and few other minor things. Engine was overhauled in 2012 and FEL-PRO HS9830PT gasket set was used and BTW cylinder heads was torqued carefully. Have anybody an idea what could cause such massive oil leak ?

I am doing my knock sensor and i need to know the torque specs for my '96 Dodge Grand Caravan 3,8L AWD. please and thanks guys!!!
