    ok so i'm replaceing my headgasket..and as i was pulling off the head i got some oil in between the bores and the block, it kinda mixed with the coolent that was alson between them, and i dont know how to drain it, but i see that there is a big bolt on the front of the block closer to the dizzy, and i was wondering if that might be a bolt i can unscrew and it would drain it? i'm not new to hondas but this is my first time takeing the head off, so i dont wanna make any mistakes...so anyone know what that bolt is or does, and can anyone help explain how to drain the coolent with oil mix? thanks

    here is a picture of where the bolt is and where some oil got mixed with coolent:

    Leave it, its fine. After the head is back on run it with water instead of coolant and then drain it and replace the coolant.

    That bolt is a drain passage, but is a bitch to remove so don't bother with it. Just ask your mom for that thing she used to suck the snot out of your nose when you were sick as a child. Suck out as much as you can from the coolant passages and if you feel you didnt get it all out, just flush the cooling system and replace with fresh coolant.

    alright so i got the head on and ran water, and then coolent, and it was maybe like 5 drops of oil, the car started up and ran fine, so thanks guys, and ya that bolt was kinda hard to unscrew i was afraid to break it so i screwed it back on, i only unscrewed it like 3 turns and gave up.

    (oh and it ran fine, but then my battery light when on and i heard wierd noise under hood, but then i heard a light pop like a valve opening or sumthing..so i thought it might have been my PCV valve just opening up)

    Even a few drops of oil can affect your cooling system. Oil can clog up your radiator and water pump if enough is ingested. Play it safe and flush the cooling system and replace with fresh coolant. Check your service manual for correct amount. Too little will cause overheating conditions. Too much will also do the same. Running water through it is the "old school" way to flush a radiator. Today, coolant is used to flush cooling systems.
