OK I have an 08 Rav4 with the 2.4. Head looks to be junk from neglect so I want to just swap out the engine. I know you can do a bunch or changeover on these but what years and models will work in this. I have so much contradicting info. 'm trying to buy a whole run and drive total from copart to save some $$$ These engines are pricey used. Please let me know the real info.
