Volvo's pink Locktite sealant liquid gasket is nothing like the silicon products , it is a liquid which is smeared over the cleaned cover surfaces with no thickness.
The silicon products are much thicker and people put far too much on which results in the small exposed oil channels getting blocked in the cover . Volvo chose the correct product .

Volvo use Loctite 5980 for the 1.6 diesel sumps . It bonds so well that you cannot get the sump off without damaging it , Mainly because the sump is wafer thin .

I have not used 5920 , the specifications below suggest it is not strong and is meant for filling gaps , of which there are non between the head and and cover of course , and it is moisture curing which is the opposite of 5980 .

"Low strength gasketing product for high temperature applications. Suitable for flexible flanges and gaps up to 1 mm.

LOCTITE® SI 5920 is a low strength, silicone-based gasketing product. It is used on flexible flanges with machined or cast surfaces and is particularly suitable for high temperature applications up to 350°C. It can be applied in gaps measuring up to 1 mm and is used in electrical insulating applications.
