bleed valve ?

[daytrader]

How do the bleed valves come out of the v6 merc block? Do they unscrew or just pull out?

[TEXAS20225]

twist them out slowly ive broke them off getting to rough with them they will come but they come better with a small amount of heat

Thankx texas, Im going to have the block hot tanked, it would be better to take them out before this is done, right?

[transomstand]

Absolutely take them out before tanking. If it was me, I'd replace them all at this point unless they're already pretty new, especially the one that feeds the top crank bearing.

Also, make sure you note the flow direction of each valve when you remove them so you no where they go. Some seal up when blowing and some seal up under vacuum.
