coolio im going to tell them again what the problem is. i swear ive told them more from the information im getting from you guys than they know! im thinking i could have rebuilt the engine myself/ as in all they did was use the haynes manual to dissasemble the engine and send off the bottom end to get done. I COULD HAVE DONE THAT! im down £1200 and 2 months. supose i do get a nice piecce of paper prooving a rebuild for the next guy!

thanks all! if any other thoughts on what the heat problem could be, lemi know!
