what are you looking to sell the car for to save yourself the trouble?post pics of the PITA
if i were you, and you were going to just junk the car anyways... try a last ditch effort for www.steelseal.com product... it will either work or it won't, and its much cheaper than the alternative to get it going...now maybe re-torquing the head bolts first would be a good idea though... either way that coolant pressurizing is definitely not good at all, but the blowby isn't so bad.
