It is a very complicated job. if you are talking about the 32 valve dual overhead cam northstar engine. you should go your local autozone or other auto parts store and buy a haynes manual which would be specific about your year and make. inside the book it states they do not advise the do it yourselfer to make that repair. alot of special tools are required. if you can get past those factors. the manual will give you step by step instructions on that repair.
