Frequently Asked Questions
C7093 is an engine- and model-specific top-end gasket kit. Because authoritative public fitment data for C7093 could not be confirmed, you should verify fitment directly on a retailer or Cometic’s website by entering your exact year, make, and model, or by cross-referencing your OEM top-end gasket kit number with Cometic’s catalog.
It is a high-performance top-end gasket kit that typically includes all gaskets and seals required to service the cylinder head and cylinder on the specified engine. The exact contents vary by application, so check the contents list or product photos for your specific model.
Most Cometic head and base gaskets are designed to be installed dry. Only use sealant where your OEM service manual specifically calls for it (usually at case splits or certain rubber gasket joints). Overuse of sealant can cause leaks or block oil passages.
Cometic’s high-performance gasket kits are commonly used in racing and high-output applications. However, you should confirm that the specific C7093 kit is recommended for your build and compression ratio and follow any surface-finish requirements Cometic specifies for MLS-style gaskets.
Head and base gaskets, especially multi-layer steel (MLS) or coated performance gaskets, are intended for one-time use. Reuse is not recommended and can lead to leaks or failure.
Installation Guide
Difficulty
Medium
Est. Time
2 hr 0 min
Tools Required
- Metric/SAE socket set (per vehicle)
- Torque wrench with appropriate range
- Ratchets and extensions
- Allen/hex keys (as required by model)
- Feeler gauges (for valve clearance if applicable)
- Plastic scraper or razor blade (for gasket surface cleaning)
- Brake cleaner or suitable solvent for degreasing
- Shop rags
- Service manual for torque specs and sequence
Pro Tips
- Always reference the factory service manual for torque specs, tightening pattern, and any sealant locations.
- Dry-fit each gasket to confirm orientation and hole alignment before final assembly.
- Use a straightedge and feeler gauge to check head and cylinder deck flatness; resurface if out of spec.
- Blow out head bolt holes with compressed air so bolts do not hydro-lock on oil or coolant.
- Allow any required sealants to skin/cure per manufacturer instructions before initial startup.
- After first heat cycle, recheck for coolant or oil leaks and verify fluid levels.
Common Mistakes to Avoid
- Reusing old or damaged gaskets instead of replacing all top-end gaskets in the kit
- Not cleaning gasket surfaces completely, leaving old material or sealant
- Installing the head gasket in the wrong orientation
- Ignoring torque sequence or torque values from the service manual
- Using excessive RTV/silicone where it is not specified by the OEM manual
- Failing to check cylinder head and cylinder deck for warpage before reassembly
Comparison vs Stock/OEM
Cometic high-performance top-end gasket kits are designed as direct replacements for OEM gaskets but often use upgraded materials and constructions (such as multi-layer steel and performance coatings) aimed at improved sealing under high cylinder pressure.
Improvements
- Superior sealing performance under high compression and high temperature conditions (depending on engine and gasket design).
- Better resistance to detonation and micro-leaks compared with some OEM composite gaskets.
- Engineered for repeated high-load use typical of racing and aggressive riding.
Considerations
- Correct surface finish and flatness are more critical with performance/MLS gaskets than with some OEM composite designs.
- Some performance gaskets may transmit slightly more combustion noise compared to softer OEM composites.
- Always verify that compression and tuning are appropriate for performance gasket usage.
Durability & Warranty
Expected Lifespan
Comparable to or better than OEM when installed on properly prepared surfaces and operated within intended performance limits.
Warranty
Standard manufacturer warranty terms only; performance use may not be covered—check Cometic’s current warranty policy.
Maintenance
No specific maintenance beyond normal engine inspection; periodically check for any signs of oil or coolant seepage after installation, especially after initial heat cycles.
