I may have got lucky. I put a cooling system pressure tester on it when I got home from work. Pumped it up to 12 psi, and went inside for a little while. Came out to head out for volleyball, and noticed a large puddle underneath the car. Found it was the lower radiator hose where it attached to the water pump. I was able to get 4-6 turns out of the screw!!! Tightened it up, and re pressurized the system to 12 psi. Left for volleyball, and just got home about 3.5 hours later, and the gauge was just a tick over 11 psi, so I lost a little, but that is probably normal. I hope this was the issue. Could I have been hearing the system sucking air through the loose hose clamp somehow?
Good to hear. I hope that is all it was. Things to consider doing for peace of mind would be.
Valve adjustment. (this will be a good time for you to inspect your cam)
Plugs, wires, cap and rotor (if they havent been done recently)
flush power steering
pull the rear drums and inspect your wheel cylinders
Possibly drain the fuel tank to get all the chunkies out of there.
And my personal favorite. Get some hella h4 housing headlights and relay your headlights. It will improve your lighting by 1000% literally. Its a very amazing upgrade for these old cars. The housings are available on amazon.com and are not terribly expensive. The lighting is better than retrofit hid's in my opinion. And they dont make you a target for cops.
And i'm a rotary guy too! If you can take care of a rotary anything you should have no problem tinkering with this car! Hope to see some pictures!!
