The HOLDEN-COMMODORE-VS-VYII-STATESMAN-VQII-WK-3-8L-V6-ECOTEC-INC-SUPERCHARGED-STEEL header gasket from Exhaust Systems Australia is the steel sealing gasket listed to fit the Holden Commodore 3.8L Ecotec V6, including the supercharged version. It's the consumable that seals the header or extractor flange to the head, not a header itself.
What is a steel header gasket and where does it sit?
A header gasket is the thin gasket clamped between the cylinder head exhaust ports and the header (extractor) flange. Its job is to seal the joint so exhaust gas leaves through the pipe rather than weeping out at the flange, which is what causes ticking leaks and lost heat. A steel gasket suits the heat cycling that an exhaust flange sees. It's a wear item: any time the headers come off the 3.8L Ecotec V6, the gasket is the part you replace rather than reuse.
Will it suit my Holden Commodore?
It's listed to fit the Holden Commodore across the VS to VYII range and the Statesman VQII and WK, on the 3.8L Ecotec V6 including the supercharged engine. Because a gasket has to match the exact port pattern of your head, send the workshop your model and engine and we'll confirm it's the right gasket before you order.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits exhaust hardware across the Illawarra, and a header gasket is usually changed while the extractors are off for service or replacement. We check the flange faces are clean and true so the new gasket seals first time. Listed to fit the 3.8L Ecotec V6; confirm the exact build with us.
What does it cost and is it a stocked item?
It's priced at $25 AUD RRP through Exhaust Systems Australia as a single steel header gasket. As a small consumable it's the kind of part worth ordering alongside the headers or a flange repair so the job is done in one visit rather than two.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
Is this the header, or just the gasket?
Just the gasket. It's the steel sealing gasket for the header-to-head flange on the 3.8L Ecotec V6, supplied as a consumable.
Does it fit the supercharged 3.8L?
Yes — it's listed to fit the 3.8L Ecotec V6 including the supercharged version across the VS to VYII Commodore and VQII/WK Statesman. Confirm your exact engine with the workshop.
Should I reuse my old gasket?
No. A header gasket is a wear item — once the flange has been unbolted it should be replaced so the joint seals properly.
