Frequently Asked Questions
Exact contents for C7235 depend on the specific engine it is designed for. Cometic top‑end kits normally include a head gasket, base gasket, and key top‑end seals (exhaust, intake, valve cover, etc.). To verify the exact pieces, you should check Cometic’s official catalog or a retailer’s contents breakdown for part C7235.
It is an aftermarket high‑performance replacement kit. Cometic designs its top‑end kits to meet or exceed OEM sealing performance and durability, often using advanced multi‑layer steel and performance‑oriented materials.
Not always, but you should check the cylinder head and cylinder deck for warpage with a straight edge and feeler gauge. If warpage exceeds the service‑limit spec in your service manual, machine work is recommended before installing any new gasket kit.
A competent home mechanic with a factory service manual, proper tools (especially a torque wrench), and some engine experience can usually install a top‑end kit. If you are unfamiliar with valve timing, piston ring installation, or torque procedures, professional installation is recommended.
Follow the engine manufacturer’s service manual and any instructions included with the Cometic kit. Many modern multi‑layer steel head gaskets are installed dry without extra sealant; some side covers or case joints may still require a thin film of liquid gasket per OEM directions.
Installation Guide
Difficulty
Medium
Est. Time
2 hr 0 min
Tools Required
- metric/SAE socket set (per vehicle spec)
- torque wrench (capable of low head‑bolt specs and higher cylinder/base specs)
- ratchets and extensions
- combination wrenches
- plastic or brass scraper for old gasket material
- brake cleaner or non‑residue solvent
- shop rags
- feeler gauges (if valve clearance adjustment is needed on the specific engine)
- service manual for the specific make/model
- thread chaser/tap set (optional, for cleaning bolt holes)
- straight edge and feeler gauge (optional, for checking head/cylinder warpage)
Pro Tips
- Always use the OEM service manual torque specs and tightening sequence for head, cylinder, and cam caps.
- Dry‑fit each gasket to confirm orientation and hole alignment before final assembly.
- Clean all mating surfaces with a plastic scraper and solvent until they are spotless and oil‑free.
- Chase head‑bolt threads and blow out the holes with compressed air so torque values are accurate.
- Lightly oil or apply assembly lube where the OEM manual specifies; do not oil MLS gaskets unless the manufacturer specifically recommends it.
- If the engine uses torque‑to‑yield head bolts, replace them instead of reusing.
- Allow the engine to fully cool after the first ride and inspect for any weeping or leaks around the head and cylinder base.
Common Mistakes to Avoid
- Reusing old, damaged, or crushed gaskets instead of the new pieces included in the kit
- Failing to thoroughly clean mating surfaces, leaving old gasket material or sealant that can cause leaks
- Not following the factory torque specs and tightening sequence for head and cylinder base bolts
- Using RTV/silicone where it is not recommended, which can affect gasket crush and sealing
- Installing the head gasket backwards or upside down when orientation matters
- Not checking cylinder head and cylinder deck for warpage before reassembly
- Neglecting to re‑torque fasteners (if recommended for that engine) after initial heat cycles
Comparison vs Stock/OEM
Cometic’s high‑performance top end gasket kits are engineered as direct replacements for OEM gaskets but typically use upgraded materials and construction aimed at better sealing under high cylinder pressures and higher temperatures.
Improvements
- Improved sealing integrity under high compression or performance use (depending on engine and compression setup)
- More consistent clamp load and sealing thanks to modern multi‑layer steel or high‑quality composite materials (where applicable)
- Better resistance to fretting, brinelling, and micro‑leaks at the head and cylinder interface
- Enhanced durability during repeated heat cycles compared to many OEM paper/composite gaskets
Considerations
- Correct surface finish and flatness are more critical with performance MLS gaskets; poor or scratched surfaces can compromise sealing.
- Always match the gasket thickness and style to your engine build (stock vs high‑compression, milled head, etc.) as changes in thickness can alter compression ratio and cam timing slightly.
Durability & Warranty
Expected Lifespan
Generally designed to last at least as long as OEM gaskets under normal use when installed on flat, clean surfaces and torqued correctly. In performance or racing use, service intervals may be shorter depending on engine build and maintenance.
Warranty
Cometic typically offers a limited warranty against defects in materials and workmanship; coverage specifics should be checked with Cometic or the selling retailer for part C7235.
Maintenance
['Monitor for any signs of coolant, oil, or combustion gas leaks around the head gasket and cylinder base.', 'Follow the engine builder’s or OEM’s recommendations for re‑torque procedures if applicable.', 'Maintain proper cooling and fueling; repeated overheating or detonation can drastically shorten gasket life.']
