Well actually i didn't notice the milky white substance in my oil when i changed it. I noticed it when i decided to look under my oil cap. It only seems to appear in my oil cap not my oil when i did my oil change. Also i just swap out the head gasket about 3 weeks ago and i torque it to spec. Is it required to remove it guys?? Or should i do a compession test first to see if its leaking? HELP!!!
