timing cover you smear some rtv a 2 inches up from the pan on both sides, (i went up to the locating pin) lay the gasket in, smear some more rtv on the gasket 2 inches up, then smear some on the oil pan gasket. nothing to thick, just a thin smear.
i just made all the bolts good and tight. all but the right side bottom 2 for the crank sensor, those are 13 ft lbs.
i also used thread sealant on the cover bolts, some of them go into the blocks coolant jackets. a little insurance, the 4 long water pump bolts get sealant for sure.
you want to use the sealant on the lim bolts too. same deal water jackets of the heads.
