Real‑world review: Full Gasket Set BB3Q-6079-AA For Ford RANGER (3.2L)
If you wrench on Ford’s 3.2L five‑cylinder (the Ranger workhorse), you already know head sealing is not the place to cut corners. This set has been trending among fleet techs I speak with—partly because it balances OEM‑style multi‑layer steel with sensible pricing, and partly because the packaging is complete enough to avoid Saturday parts runs.
What’s happening in gasket tech (quick take)
Industry trend-wise, MLS head gaskets with fluoroelastomer (FKM/Viton) coatings are now the baseline for modern turbo diesels. Graphite composite carrier gaskets are still common for exhaust and EGR joints, and bead‑embossed stainless is the norm for turbo interfaces. To be honest, the gap between premium aftermarket and OEM has narrowed—testing and coatings have improved a lot in the last five years.
Product specifications
| Part number | BB3Q-6079-AA (full set) |
| Engine compatibility | Ford Ranger 3.2L Duratorq TDCi (≈2011–2019), commonly known as P5AT |
| Head gasket | MLS (stainless steel, multi-layer) with FKM coating; fire ring emboss beads |
| Typical thickness | ≈1.20–1.35 mm (real-world use may vary by variant) |
| Heat resistance | Up to 300°C on MLS core; up to 230°C for FKM surfaces |
| Kit contents | Head gasket, valve cover, intake/exhaust manifold gaskets, turbo/EGR gaskets, stem seals, ancillary seals and O‑rings |
| Origin | 289 Heping East Road, Chang’an District, Shijiazhuang, Hebei, China |
How it’s made and tested
- Materials: SUS301/304 stainless stacks, nitrile/graphite composites for hot-side gaskets, FKM coated sealing faces.
- Methods: Progressive‑die stamping, laser cutting on tight-tolerance parts, bead embossing, and controlled adhesive lamination.
- Testing standards: Compressibility/Recovery per ASTM F36; Sealability per ASTM F37; QMS audited to ISO 9001 and IATF 16949.
- Service life (field): Many customers report 150,000–250,000 km on fleet Rangers, assuming proper surface prep and torque sequence.
- Sample data: Oil sealability ≤ 0.5 ml/hr at 1.0 MPa; Recovery ≥ 55% (F36) on composite coupons; salt‑spray on coated MLS per ISO 9227: 72–96 h no red rust at edges.
Where it shines
Typical use cases: post‑overheat rebuilds, turbo refreshes where EGR/turbo gaskets must be replaced, and scheduled top‑end services on high‑mileage fleets. In mining and agriculture (dusty duty cycles), the Full Gasket Set BB3Q-6079-AA For Ford RANGER helps avoid repeat teardowns—one box, fewer surprises.
Mechanic chatter, anecdotally: “coating doesn’t stick to the deck when removed,” “stem seals hold up to higher EGT towing,” and “no weep at coolant jackets after 10k km.” Not scientific, but it tracks with the lab numbers.
Vendor comparison (quick glance)
| Vendor | Material stack | Certs | Warranty | Lead time | Notes |
|---|---|---|---|---|---|
| This set (Full Gasket Set BB3Q-6079-AA For Ford RANGER) | MLS + FKM; graphite composites where appropriate | ISO 9001 / IATF 16949 (factory level) | 12 mo. typical (confirm per dealer) | 3–10 days, region‑dependent | Balanced cost/quality |
| OEM dealer kit | OEM MLS; full accessories | OEM QMS | 12–24 mo. | Stock‑dependent | Highest price, predictable fit |
| Low‑cost aftermarket | Composite head gaskets (varies) | Mixed/unknown | Short | Immediate | Risk of early seepage |
Customization and a quick case study
Customization options I’ve seen: alternate thickness shims, upgraded turbo gasket alloy, and high-temp valve stem seals for heavy tow users. OEM‑ish, but practical.
Case: A Queensland contractor running PX Rangers in dusty quarries switched to the Full Gasket Set BB3Q-6079-AA For Ford RANGER. After 60,000 km, borescope checks showed clean sealing faces and no coolant dye trace. They kept the same torque‑to‑yield bolt protocol from Ford’s workshop manual—no drama, no comebacks. That’s the ballgame.
Install notes (because someone will ask)
- Check deck flatness and RA; MLS wants a smoother finish than old composites.
- Follow the Ford torque/angle sequence; replace TTY head bolts.
- Retorque not required on MLS, but re‑check ancillary fasteners after heat cycles.
Certifications/quality framework referenced: ISO 9001, IATF 16949, PPAP. Lab methods include ASTM F36 and F37; corrosion per ISO 9227.
