Sealant bead thickness: 2 to 3 mm.
The sealant bead may not be thicker than specified, otherwise excess sealant could enter the oil pan and clog the oil intake pipe screen.
The oil pan must be installed within five minutes of being applied with sealant.
After installing the cover, allow the sealant to harden for approximately 30 minutes. Only afterward may the engine oil be replenished.
