leaking

After a few minutes the water level rises about 5” on gauge and it gets to 1.5lb to quickly, it used to take 10 minutes to shut off at 1.5lb . Then it shuts off from 1.5 pressure and water drops so auto fill comes on . When it cools water it is about 6” to high . Boiler went to top one day from this then I cleaned the auto fill and low water cut off , the two Mcdonnal miller on the boiler . The water fill valve I did not touch . I just replaced vents on boiler with old but I think good ones . I cleaned all feed pipes on boiler I could . It was ok for a few days . Now it’s doing it again . I was getting a 14 minutes cycle about every hour , now after one minute it hits pressure limit of 1.5. I think my cleaning did it. Thanks
