Yeh it's been a long time between drinks for me as well last one I ever did was a 327 chev I had in an old 71 Hg Holden but the prices people are charging these days and my son had already bought the rebuild kit all I have to get is timing chain kit and water pump everything else is there plus there is so many gaskets and seals in the kit im going to try and replace everything it's a shame about the 3rd cat getting blocked I only found that out on YouTube was a bloke on there with the same trd supercharged aurion and he went through 4 motors in 12mths until toyota themselves found what was causing the damage I think they should be replacing the engine should maybe of been a recall
