holden 6 litre v8 problems

Holden’s 6.0‑litre V8 (L98/L76/L77) is a tough Aussie crowd-pleaser, but like any rock star it has a few backstage tantrums—especially AFM-equipped versions.

If you’re hearing ticks, smelling oil, or watching the oil-pressure needle do the hokey pokey, you’re not imagining things.

• AFM lifter collapse and cam wear (mainly L76/L77 autos): misfire/tick at idle; many delete AFM when repairing.
• Hardened oil pickup O‑ring: low hot oil pressure, intermittent lifter noise; sump-off fix.
• Oil leaks from rear main, sump and valley cover gaskets.
• Harmonic balancer delamination causing wobble and belt squeal.
• Exhaust manifold bolt/gasket leaks (cold-start tick), and sagging engine mounts.
• Ageing water pumps, radiators and hoses—overheating on hard Aussie summers if neglected.

Good oil (changed on time), a healthy cooling system and attentive ears go a long way; service history is king. Get a pre‑purchase inspection, and budget sensibly—parts are common, but “cheap V8” dreams sometimes come with concerto-level ticking.
