hsukaria,
Your post made me look at the pictures again.
It does not appear as if the lead ( could be tin or a soldering alloy ) has been melted upon the back cover. It does not reach the flange all around and its surface is not smooth.
Suspicions are that it was formed away from the back cover and can very well have been cemented.
Still with the back cover removed from the engine it may be worth trying some low heat from a hair dryer or a heat gun being carefull to heat it up slowly and watch what is happening.
When there is a will there is a way ... L O L
