Our Buick started to over heat and lost power. Mechanic told us the head gaskets were hooped. Looking on line, some say the intake upper and or lower gaskets are hooped. I do have a small oil leak from up behind the engine some where. Fire wall side. I am looking at taking the heads off and maybe the intake? Never attempted this before. Looking for help in how to disassemble.
Thanks in advance
