Clean all sealant from block and sump, apply a bead of silicone with the nozzle cut at the front mark, fit the sump immediately and tighten as specified. Wait about 30 minutes before filling with oil.

• Check the sealing compound expiry date before use.
• Cut the tube nozzle so the bead is about 3 mm; a thicker bead can block the oil strainer.
• Sealing faces must be free of oil and grease; scrape the block, brush the sump.
• Fit and tighten the sump immediately after applying sealant.
• With gearbox fitted the sump must rest against it; with gearbox off, it must be flush with the block.
• Let the sealant cure for about 30 minutes before filling with engine oil.
