Moisture in distributor after every rain

[rahatclinic.khi1]

I have a Daihatsu Cuore CX automatic 2007. I bought it 2011 & changed point by CDI ignition.
Now after almost 13 years (since i bought it) whenever its rain dampness comes into distributor & it doesn't starts after multiple ignite/self, & sometimes my battery goes down due to multiple self/ignite attempts. Then i have to open the distributor clean it & warm it then again fix it, then it starts and if battery down then after cleaning, warming and fixing the distributor i have to use my other car for booster/jump start with other battery. Jump start/booster is only required if i attempts to start it with multiple self/ignite. Else only cleaning & warming of distributor is enough. And if there's shining sunlight for 3-4 hrs after rain then there's no need of anything. This also happens after a complete carwash at car wash station or after pressure washer.
Can some one please advise me what to do to avoid this moisture in my car's distributor?

Your distributor cap requires a gasket to be installed between it and the body of the distributor. The gasket seals the cap to the body of the distributor to prevent moisture ingress.

Don't pressure wash your car's engine bay. Electronics and ignition system components don't like water.

Your distributor cap needs replacement. As it is nit tightly packed, so water is sweeping inside and causing moisture
