the tq for the rear cover is less then snug, be sure to use some blue loctite. also front and rear covers, run some rtv 2 inches from the bottom up on both sides the gasket, thats a leak point on both covers. use a straight edge across the bottom of the block and the rear cover to make sure its sitting in place flush. theres small plastic spacers on each bolt, dont worry if some are broken. try not to break em tho lol the straight edge will align the cover for ya.

thread sealant goes on the 4 long water pump bolts and the all the lim bolts cause they all go into the coolant parts of the block.
