Parts for your 2014 Holden Commodore-Head gasket

2014 Holden Commodore head gasket

Yes, the 2014 Holden Commodore uses a head gasket. Technical sources including the Holden VF Commodore Service Manual and GM Global Service Information (GSI)/ACDelco Technical Delivery System list full cylinder-head removal and installation procedures for the VF’s petrol engines — the 3.0L V6 (LFW), 3.6L V6 (LFX) and 6.0L V8 (L77) — specifying multi-layer steel (MLS) head gaskets and torque‑to‑yield head bolts. That factory guidance confirms the head gasket is a standard, critical component on this model.

On a 2014 Commodore, the head gasket’s job is to seal the cylinder head to the engine block so combustion pressure stays where it should, while keeping coolant and oil in their own passages. It has to cope with big temperature swings and high cylinder pressures, which is why Holden/GM uses robust MLS gaskets paired with stretch (TTY) head bolts for clamping consistency.

It’s not a routine service item — a healthy engine can run its whole life on the original gasket. The real key is preventing overheating. Stick to the logbook schedule, use the correct GM‑approved long‑life coolant, and keep the cooling system tidy: radiator, thermostat, water pump and cap all need to be in good nick. If the car ever runs hot, it’s worth getting it checked promptly to protect the gasket and the alloy heads.

• Common warning signs include unexplained coolant loss, sweet‑smelling white exhaust smoke, milky residue on the oil cap, bubbles in the overflow bottle, pressurised hoses when cold, rough cold starts, misfires, or creeping temperatures on hills.

If replacement is needed, it’s a proper workshop job. The heads come off, surfaces are cleaned and checked with a straightedge, if they’re out of spec they’re sent for machining. New MLS gaskets and new torque‑to‑yield head bolts go in, following the exact GM torque‑angle sequence. It’s smart to flush the cooling system and oil, and to inspect related parts while it’s apart — think timing components, valve stem seals, water pump and hoses. Done right, the repair restores compression, stops cross‑contamination, and brings temps and performance back to normal.

Cost and downtime vary by engine and what’s found once it’s opened, but most owners should plan for professional labour and a couple of days off the road. Using quality OE‑spec parts and sticking to the factory procedure pays for itself in reliability.

Popular questions about 2014 Holden Commodore head gaskets

Does a 2014 Holden Commodore have a head gasket?
Yes. Factory service information for the VF Commodore’s LFW 3.0 V6, LFX 3.6 V6 and L77 6.0 V8 documents MLS head gaskets and head bolt torque sequences, so the part is absolutely fitted to these engines.

How long should a head gasket last on a VF Commodore?
With correct coolant and no overheating, many last the life of the engine. Usage and maintenance matter most — cars that see regular cooling‑system care can cover very high kilometres without gasket drama.

Will a “stop‑leak” fix a blown head gasket?
It’s at best a temporary band‑aid and can clog radiators and heater cores. Proper diagnosis with a pressure test and combustion‑gas test, followed by a correct gasket replacement, is the reliable fix.
