Bad head gasket?
Stopped at a gas station and routinely checked the oil to find a rusty liquid all the way up the dipstick, and then a milky white color in the oil at the bottom. (just changed the oil about 5 days ago and there was no coolant in it at all)
How to tell if this is a head gasket going bad or coolant leaking into the timing cover, I did notice a small puddle of coolant siting behind the waterpump.
-Can't see white smoke in the exhaust, but I will check later to see if any comes out upon cold-starting.
-Also the engine is not overheating like a typical bad head-gasket, it's actually not getting up to temperature at all (changed thermostat last month), or the sending unit is bad.
