question bout oil leak

[lorenzob]

i have got a bad oil leak and i can't figure out were it is coming from. when i changed out the motor i replaced most of the seals and gaskets also recently have replaced the oil pan gasket. i don't know where else it would be leaking from cuz i can't see no cracks or anythang. i am thinking that maybe it might be the main seals but for one i don't know how hard they are to change and then don't know where they are and how to check them. if someone knows how they might be able to help me or to check them or whatever i might have to do let me know please.

rearmain seal replacement:
1) Remove transaxle (transmision)
2) Remove flywheel/driveplate
3) Remove the rear oil seal retainer from the block. NOTE. several oil pan bolts will have to be removed if pan is till in place, so replacing the pan gasket during this repair is recomended.
4) Scrape any sealant or gasket material from the retainer, oil pan and block. Warning, aluminum blocks can be gouged very easily.
5) Position the seal and retainer assembly between two wood blocks, to evenly support the aluminum housing, and drive the old seal out with a hammer and punch. A screwdriver can also be used to pry the seal out, being careful not to gouge or nick the housing during seal removal.
6) Place the new seal squarely on the retainer and drive it into the retainer with a wood block.
7) Lubricate the crankshaft seal journal and the lip of the new seal with multi-purpose grease.
8) Apply a thin layer of RTV sealant (hi temp pressure resistant RTV is best) to the seal retainer. Also apply sealant to the bottom of the retainer where the oil pan mates with it.
9) Slowly and carefully push the seal onto the crankshaft. The seal lip will be stiff, so work it onto the crank with a smooth object such as the end of a socket extension as you push the retainer against the block.
10) Install and tighten the retainer bolts securely. The bottom sealing flange of the retainer must not extend below the bottom sealing surface of the block.
11) Remaining steps are reverse of removal.
