sorry Deezee, duff info from me this time,
yes you are correct, air in the oil making it froth is not good, tho i didn,t mean it to that degree,
my own sump has been chopped but extended to still allow the correct qty of oil tho the level is not the same as original sump due to the "floor" of the sump being raised up,
sometimes the brain gets all befuddled
cheers
