How To Disassemble My Distributor? Options

[j0ch0a94ST]

Hey guys I've had an issue with my 94 ST running rough until it reaches operating temps ever since I washed the motor. I pulled the plugs and replaced the plugs. There was no water in the chambers. I have pulled the dizzy cap off and there was some moisture inside. I have dried out the cap and sanded down the terminals inside. I have currently pulled the distributor out of the car. So how do I disassemble it to look for trapped water? I've pulled out the 4 main screws but the plastic covers are blocked from coming off by the rotor button. There isn't a screw or anything holding the rotor cap on but it seems stuck. They do come off right? I just don't want to break anything. Anyone with any experience with this please help.

Thanks

Cleaned the cap and rotor. I have ruled out the dizzy now I fear its an 02 sensor or a vaccum leak. It only runs rough(misfires) when its cold. After it runs and gets warm it runs better but has significant power loss. The wash happened about 3 weeks ago so I think any of that water has evaporated by now.
