I clean the engines with atomic cocktail,engine degreaser plus some fairy liquid and lots of love
Right so the engine nearly dressed up and ready to jump in to the new home/body
M50 manifold is on,fuel rail brackets made up,M50 crank breather system installed(good we had one M50 lying around),also bracket for dipstick fabricated,and few other minor things tidied up
