1996 Buick PARK AVE leaking antifreeze into oil

Well, if you put all new gaskets in and still have leak did you have any machine work done or have head and block checked for warpage? Did it ever run really hot on you? Maybe that warped mating surfaces and will not seal until you have them smoothed out or replaced. It's a royal pain but I think I would pull head off and have it checked to see if this might have happened. Possibly could be intake also but does sound more like head to me. Lots a' luck?

Yes both heads were warped due to overheating had them milled and had block checked and honed, found damage at front engine cover replaced and is still leaking down, sent lower intake to shop they had no way to pressure check so they cleaned and inspected, :) thx for speedy reply !
