The Redback DSF778C is a header gasket listed to fit the Toyota 4Runner 3.0L V6 (3VZ). It's the sealing gasket that sits between the cylinder head and the extractors or exhaust manifold, not a complete exhaust part on its own.
What is the DSF778C?
The DSF778C is a header (exhaust manifold) gasket supplied by Redback. Its job is to seal the joint where the headers or manifold bolt to the cylinder head so exhaust gas doesn't leak at the port face. It's a consumable: any time the extractors or manifold come off the 4Runner's 3.0L V6, the gasket should be replaced rather than reused, because once a gasket has been crushed and heat-cycled it rarely seals a second time.
What does a header gasket do and why does it matter?
A header gasket takes up the small imperfections between two metal faces and holds the seal through repeated heating and cooling. When it fails you get an exhaust leak at the head — typically a tick or hiss that's loudest cold, and sometimes a smell in the cabin. Because it's a sealing component rather than a performance part, the trade-off is simple: fit a fresh one whenever the manifold is disturbed and you avoid chasing leaks later.
Will it suit my Toyota 4Runner?
The DSF778C is listed to fit the Toyota 4Runner with the 3.0L V6 (3VZ) engine. Gaskets are port-pattern specific, so the safest check is to confirm your exact engine and head before ordering — send us the details and we'll match it. We treat the listing as listed to fit rather than promised until your build is confirmed.
What does fitting involve at our Illawarra workshop?
At $6.89 the DSF778C is an inexpensive part, but it's worth doing properly. Oak Flats Muffler Men fits it as part of any header or manifold job across the Illawarra: we clean the head and manifold faces, check them for warpage, set the gasket dry, and torque the fasteners evenly so the seal holds. Bring it in with the manifold work and we'll handle it on the hoist.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- What is the DSF778C exactly?
- It's a header gasket — the seal between the cylinder head and the headers or exhaust manifold on the Toyota 4Runner 3.0L V6 (3VZ). It is not a full exhaust system.
- Do I need to replace the gasket every time the manifold comes off?
- Yes — a header gasket is a single-use consumable. Once it has been crushed and heat-cycled it rarely seals again, so fit a fresh one whenever the manifold is disturbed.
- Can Oak Flats Muffler Men fit it?
- Yes. We fit it as part of header or manifold work in the Illawarra, cleaning the faces and torquing the fasteners evenly so the seal holds.
