Instructions

Inspect the spark plugs if the Rover fails to start, idles roughly or accelerates poorly. Open the bonnet of the car; the spark plugs will be easily accessible from the front and sides. To avoid mixing up spark plugs, only remove one at a time. Use the torque wrench to remove the bolt securing the spark plug to the cylinder head.

Unscrew the spark plug using a spark plug wrench or a ratchet with spark plug socket. Inspect the cylinder and sealing surfaces for signs of wear or damage. If wear or damage are present, consult a professional service technician. Measure the spark plug electrode gap using the wire-type feeler gauge. A gap that is too big or too small may impede proper functioning.

Measure the gap, and if it does not meet manufacturer specifications, bend open or closed the outer plug electrode until the correct gap size is achieved. Ensure that the connector threads are undamaged. Brown stains on the porcelain just above the body are normal, and not an indication of damage.

When reinstalling or replacing a spark plug, wipe down the cylinder head thread and sealing surface with a clean cloth.

Check the battery terminals for corrosion if the car has trouble starting or has diminished performance. Battery corrosion can impede electrical performance. Corrosion will look like white, fluffy deposits around the terminals.

Scrub the terminals with a soft wire brush and a solution of warm water and baking soda to remove corrosion. Rinse all areas with clean water.

Tighten the battery leads and terminal connectors. A loose connection can impede or prevent electrical functioning. Do not continue to use the car when electrical systems are operating only intermittently, as this can cause further damage to other components.

Inspect and clean the distributor cap if the car has difficulty starting or is prone to stall. Using a wrench, unscrew the two restraining screws holding the distributor cap to the distributor.

Remove the O-ring seal from the base of the cap. Wipe the interior of the cap with a clean, dry cloth until all debris are removed. Inspect the interior of the cap for burn marks, cracks or black tracking marks.

If there is no damage to the cap, reinsert the O-ring and reattach the cap to the distributor. If the cap is cracked or otherwise damaged, replace the distributor cap with a new one.
