Fitting tips

1. Clean both gasket faces without scratching them.
2. Fit the gasket dry; a dab of grease can hold it in place during reassembly.
3. Tighten the screws in a criss-cross pattern, without forcing, to the manufacturer's torque.
4. On an engine where the ignition runs in oil, top up the oil level after reassembly.

No: a paper or fibre gasket tears or stays crushed when removed. If you're opening several covers, a complete engine gasket kit often works out cheaper.
