I'm halfway through removing my sump. Have removed the mainfold and have the car up on stands so access is good. Front part of the sump is detached but the back is still attached and I'm struggling to access with a Stanley knife to cut the silicon. Looking for advice how I can get it seperated. Tempted just to tug and yank it but worried about damaging the pickup pipe. Is the pickup located in the shallow or deep end of the sump? Cheers.
