Fel-Pro Engine Oil Pan Gasket Set OS 13260T for Classic Ford Mustang V8 — Cork-Rubber, Leak-Resistant

Fel-Pro OS 13260 T is an engine oil pan gasket set engineered to restore a reliable, oil-tight seal on compatible classic Ford and performance V8 engines.

This gasket kit from Fel-Pro uses a cork-rubber compound and includes the parts needed to reseal the oil pan area on the specified vehicle applications. Designed for repair shops and DIY restorers, the set compensates for imperfect sealing surfaces and has been validated in real-world on-vehicle testing. It’s a targeted solution when an oil pan leak or gasket failure needs a long-lasting mechanical seal rather than a temporary patch.

Which vehicles and engines does this gasket set fit?

The OS 13260 T is specified for a range of classic and specialty vehicles—primarily older Ford and Shelby applications—so confirm fitment for your exact year, make, model, engine, and trim before ordering. Compatibility varies by production year and sub-model; Fel-Pro and retailer fitment tools can verify specific matches.

• Intended for classic Ford and Shelby/Cobra V8 platforms and select TVR models.
• Check online fitment tables or the seller’s vehicle selector to confirm compatibility.
• Includes notes for applications with additional qualifiers—read fitment details carefully.

How does the cork-rubber construction help on older engines?

The proprietary cork-rubber formulation is more compliant than rigid gaskets, enabling it to conform to uneven or slightly warped sealing surfaces common on service-aged oil pans and blocks. That flexibility improves sealing performance without requiring resurfacing in many cases.

• Highly conformable material fills small surface irregularities to reduce seepage.
• Designed for repair scenarios rather than perfect factory tolerances.
• Resists oil exposure and compression set typical of engine service environments.

What does the kit include and how does it simplify the repair?

Fel-Pro gasket sets are packaged to provide the components needed to complete the oil pan reseal for the listed applications. Including the correct gasket profile and any supplementary parts avoids mid-repair trips to source missing items and helps ensure a correct fit the first time.

• Complete oil pan gasket molded to the correct contour for the application.
• Designed to be a one-stop kit—most repair needs for the pan area are covered.
• Manufactured and tested on-vehicle to validate fit and performance under real conditions.

How should I verify this is the right part before installing?

Always use the retailer’s fitment checker and your vehicle’s exact year, model, engine size, and trim level before purchase. If the online fitment indicator shows notes or qualifiers, read them; some classic and special-edition cars require additional verification.

• Enter year, make, model, engine, and trim into the fitment tool before ordering.
• Review any fitment notes or special instructions provided by the seller or manufacturer.
• Compare the new gasket to the old part for bolt pattern and sealing flange alignment prior to final installation.

Who is this for: This Fel-Pro OS 13260 T set is suited to mechanics, restoration enthusiasts, and owners of compatible classic Fords, Shelby/Cobra cars, and select TVR models who need a durable oil pan reseal. It’s aimed at repairs where a field-ready, conformable gasket material is preferred to accommodate worn or imperfect mating surfaces, helping avoid unnecessary machining while restoring oil-tight performance.
