Oil Leaks

Symptoms

Oil on the garage floor, oil smell, oil coating on the underside of the engine.

Cause

The 253 and 308 share the same rope-style rear main seal as the Holden six, it always leaks eventually. The rocker cover gaskets, timing cover seal, and oil pan gasket all deteriorate with age.

Fix

Replace gaskets and seals as needed.

The rear main seal requires engine or gearbox removal ($500-1,000 at a workshop).

Many owners tolerate a slow leak.

Cost mentioned in fix
$500-1,000
