Do I Need to Use Sealant with the WTA Gasket Kits?

Engine professionals want clear guidance when it comes to sealants: Do I need to use sealant with the WTA gasket kits? Choosing the right installation method can impact reliability, warranty, and service costs. This article provides concise, expert-backed information for optimal sealing results.

When Are Sealants Needed with WTA Gasket Kits?

- Most WTA gasket kits are designed for direct installation and do not require additional sealant.

- WTA gaskets feature precision surfaces and OE-quality materials that deliver optimal sealing performance as-supplied.

- Excessive or improper use of sealant can:

- Compromise gasket material integrity

- Cause uneven gasket seating

- Obstruct oil or coolant passages

OE Recommendations and Industry Standards

- Major OEMs (Original Equipment Manufacturers) specify no additional sealants are typically needed with modern multi-layer steel (MLS) and elastomer-coated WTA gaskets ((https://www.motor.com/magazine-summary/the-basics-of-modern-gasket-technology/)).

- Exceptions:

- Small dab of high-temp RTV at specific joint corners (e.g., cam bridges, timing cover joints)

- Refer to OE service manuals for any unique instructions.

When Should Sealant Be Used with WTA Gasket Kits?

- Exceptions may include:

- As indicated in the WTA installation instructions or OE technical bulletins

- Uneven or pitted sealing surfaces (not recommended in regular professional rebuilds)

- Use only OEM-approved sealants, applied sparingly and only at specified locations.

Best Practices for Gasket Kit Installation

- Always follow WTA and OEM instructions for each engine model.

- Clean and dry all mating surfaces before installation to maximize gasket seal.

- Double-check torque specs and sequence to ensure proper seating.

Engine Damage Risk: Overusing Sealant

- Over-application can result in excess squeeze-out, contaminating internal engine components.

- Silicone fragments can block oil galleries, causing engine failure ((https://www.aapexshow.com/blog/beware-of-excess-sealant-a-critical-engine-repair-mistake/)).

WTA Gasket Kits: Designed for Direct Use

- All main components are rigorously tested for leak-free performance without additional products.

- For most applications, no added sealant is required—ensuring quicker, cleaner, more reliable repairs.

Quick Reference: Sealant Use with WTA Gasket Kits

- Check WTA product instructions per application.

- Use extra sealant only when specifically recommended by WTA or the OEM.

- When in doubt, consult WTA’s technical support or OE service data.
