in 2 days a gone to do this my engine is in the bay i have the exhaut and starter off

need to clean the old silicon sealer

i think i gone do it like this

the block is clean
and the i put 4 screws on all corner of the new sump seal to center it first on the engine bloc and fix it with super glue
wait that it is good fixed and care that it is on goood place and take the 4 srew off

than put silicion sealer on it and fixe the sump

good idee? but the problem is that there gone a be only on one side silicon seal
