I bought some aftermarket oil cooler lines. I have now put them on three times and the oil still comes out of the oil filter housing where the lines screw in. Can anyone tell me how many and where to put the o-ring seals in. There were no instructions with the lines. Or should I just get some OEM lines. I tried one o-ring and then two o-rings with the same result.

Thank You
