sealant on sumps is an engine killer as said.
99.95 % of diy mecanics put way to much sealant on thinking they are doing a better job. problem is if any squidges out on the outside you can bet your life at least as much has squidged out on the inside.
hot oil has magical ablity to loosten these bits they will clog the oil pump pickup.
get it all clean, don't overtoque the bolts and no need for sealer,
