same with the fiesta zetec i have it has slight slant on the bottom of the sump

Have a look at Saturn website,if he has updated the G20 photos you will see how far back you can get the engine and I fitted the zetec the other weekend its better to trial fit it as the book placement of mounting plates will not fit properly,the engine mount on the o/s/f is close to the very edge of the plate,the stat housing is the problem and mine is a one off.
