so I have a 96 ls, chassie has 130000 miles, motor has god nows how much mileage.

So for my water temp gague it will jump like 1/2 the width of the needle, like very little. But it does it at predictable times, like when i come to a stop light, sit and sit, then go. As soon as the rpms raise my water temp will just drop, like half the width of the needle.soes this sound like beginning of blowing a head gastet.

I dunno, was short 1 quart of oil a few weeks ago and for some reason I think everything is going wrong with me car.
