hey there, 3 things happend about 3 weeks to a month ago with my fj60. early morning heading home from work my oil gauge started to move up and down, not alot but enough to notice. Also the normal valve/rocker arm sound got louder. So i shut the engine off and checked the oil and it was good as in not low. I also looked for oil leaks in the obvious places and none to be found. i started it up and made a mad dash home parked it. it has basically sat there for a while and last week i finally was able to get the valve cover off and found a little bit of the creamy water/oil sludge up by cylinder one (we are talking very little) also none on the under side of the valve cover. there was however a bit more under oil cap. i found more creamy sludge in the top side of the pcv valve. i guess what i am asking does this sound like the start of a head gasket getting ready to go. i hope my story makes some sense. if you need pictures i can post pictures.
thanks for your time
