Kent-Moore J-41480 - Front and rear cover alignment tool; at oil pan:
Our friend the J 41480 is now tightened to the engine block, leaving the tool-to-front-cover bolts loose at this time. Like when used on the rear cover, these bolts get 18 lb-ft of torque.

Kent-Moore J-41476 - Front and rear cover alignment tool:
Unlike the seal in the rear cover, the crankshaft front oil seal is not actually contacting any crank surfaces at this point; instead, it will ride on the harmonic damper (to be installed later). Therefore, the seal isn't doing anything to help align the cover to the block. Enter the J 41476 Front and Rear Cover Alignment Tool (Crankshaft Seal Area), also made by SPX Kent-Moore. This is installed hand tight using an old crank bolt. Note the alignment tabs on the cover that the tool presses up against; this tool aligns the cover side-to-side.

i think witht he ls1 the oil pans a structural part of the engine, wich would mean it sees some stresses from the motor if its not lined up right i could see the pan beeing weaker in the wrong orientation..
