All modern Toyota engines have a formed in place gasket (FIPG or sealant as you call it) on the timing chain cover(s) where they mate to the block. The ones I’ve been elbows deep on tend to use an o-ring to seal where the oil circuit passes from the front cover to the block. The FA20 used the above mentioned FIPG there. Just a slightly different way to skin the proverbial cat. The repair manual should have called out that hole was an oil circuit and excess FIPG would be problematic.
