1995 v-6, 5 speed. I got it from the first owner, so i have the whole history of it. But it does have 190,000 miles and has a slight oil leak. I have to get under there and clean the engine to pin point it, but since it does not leak much, and I smell it, does it mean maybe the valve cover gasket? Cleaning the engine is the best way to find a little leak right? and when I am at a street light, my oil pressure drops, but goes up again when I accelerate, is that a sign of a problem? and my Temp gauge will go up and down randomly, so I am thinking a sticky thermostat? Sometimes it gets close to being in the red zone, but it dosent, but it still worries me.
