I have a 2nd gen 88 max and when I crank it up in the morning and rev it I hear sounds, like water is running through my dash, I thought maybe it was just me but Ive heard it recently too. What could this be? Obviously its nothing bad, I dont think, because there hasnt been any signs of anything bad.

 

air in your coolant lines.....open them up or flush your coolant, either will do...problem solved..
