i was 99.9% almost done removing the vtec solenoid to replace the screen and gasket but this stupid bolt kept me from removing it, o little bolt, i had everything take apart, it was just that one bolt holding the solenoid to the head, but i could not get it off, i could only use a rachet, i did not have enough space, kept hitting the thermo housing, so i guess ill have to do it when i change the thermostat, sux
