Hi there all, i have a 2002 2.4 2AZ-FE previa that has a blown headgasket. I stripped the engine down to remove the cylinder head, however, it turned out that someone else had done the same at somepoint and has rounded off every single head bolt(yup.... every single one... the mind boggles). Has anyone any ideas on how to get them out without removing the engine? I currently have the one engine mount off so I can jack the engine down but, I still dont think i can get a drill in there to drill the heads off.
I really don't want to get rid of the mpv if possible as I love it. Any ideas are welcome at this point.
