Pressure cap is on the overflow bottle. Front end has been jacked up 1.5 ft. throughout the whole process.
I didn't have a problem with my Skylark like this.

The fan works now so that'* not an issue anymore.

Every time it'* warmed up, the thermostat opens, a little later the fan kicks in at 230 with digital thermometer. I shut the car off and open the bleeders to let the air out. It takes 4 to 5 minutes to let the air out each time. About 20 times now.

Looks like tomorrow I'm going to pull the head to see what the last fellow did.

You could always try drilling a hole in the T-stat.

No, that wouldn't do anything. The thermostat is behind the water pump. It seems that I am pumping more air into the system every time I run it.

It would work. No matter where air is entering the system it will get trapped behind the T-stat.

If you have air entering the system can you do a pressure check to see where the leak is?

The cooling system is pressurized and leaks out, not in. The only thing that will cause air to enter the cooling system is from a source that has higher pressure than the cooling system. You might have a head gasket issue.

Yup, that'* why I'm going to pull the head. A friend bought the car with a remaned head already installed by the last owner. The car has not been on the road since.

I second drilling a hole in the T Stat, I drilled a 5/32" hole at the 12.0 clock position of the thermostat, when installing make sure the hole stays at that position.

Hopefully your heads are in good shape, let us know what you find out.

Looks like a defective head gasket. There is a fair size bump under the coating between #1 cylinder and the rear corner cooling port.

maybe use a block tester to test for exhaust in the coolant. or a compression test before just jumping into tearing it apart.could always use the old aspirin trick to hold the thermostat open.Makes life easier with one of these.!!
