Haima S7 Valve House (Part No.: 484Q-10-220-T)

Think of this as your Haima S7’s “engine valve protector”—not just a metal cover, but a precision-sealed component that shields the engine’s valve train and keeps critical parts lubricated. It’s a sturdy assembly made of high-grade aluminum alloy (lightweight yet tough enough to resist engine heat and vibration) or reinforced plastic (for corrosion resistance), with a built-in rubber gasket (creates an airtight seal) and pre-drilled bolt holes (locks it tightly to the engine cylinder head). Mounted on top of the Haima S7’s engine cylinder head, it covers the valve train—including components like valves, camshafts, valve springs, and rocker arms.

Its main job is to act as a barrier: it keeps dirt, dust, and road debris out of the valve train (preventing premature wear or jamming) and holds engine oil inside (lubricating the moving valve parts to reduce friction). Without a working valve house, oil would leak out of the engine (causing low oil levels and overheating) and contaminants would get in (damaging expensive valve components). It also helps muffle engine noise—since the valve train’s moving parts are enclosed, it reduces the clattering sound of valves opening and closing.

This valve house is exclusive to Haima S7 (equipped with the 484Q engine)—always check your vehicle’s VIN to confirm fitment! Haima tailored it to the S7’s engine specs: its shape and size match the 484Q cylinder head exactly (no gaps or misalignment), its gasket groove fits the original rubber gasket (ensures a leak-free seal), and its bolt holes line up with the cylinder head’s threaded ports (no forced installation). Grab a generic valve house or one for other models? You’ll run into issues: oil leaks (from poor sealing), misfit (blocks valve movement), or heat damage (from material that can’t handle the 484Q engine’s operating temperature).

 Core Jobs: Protect Valve Train & Seal Engine Oil

As a key engine component for the S7, it has three non-negotiable roles:

Shield valve components: It encloses the valve train, keeping out dirt, sand, and moisture—preventing scratches on camshafts, jamming of valve springs, or corrosion of rocker arms.

Prevent oil leaks: The rubber gasket creates a tight seal between the valve house and cylinder head, ensuring engine oil stays inside to lubricate the valve train (no leaks that lead to low oil pressure or engine damage).

Reduce engine noise: By covering the moving valve parts, it dampens the mechanical sound of valves and camshafts—making the S7’s engine run quieter, especially at idle or low speeds.

This 484Q-10-220-T valve house only fits Haima S7 with the 484Q engine—wrong fit means oil leaks or engine damage:

Fits These: All Haima S7 variants equipped with the 484Q engine (matches cylinder head shape, gasket size, and bolt pattern—confirm with VIN).

Won’t Fit These:

Haima S7 with other engines: If your S7 has a different engine model (not 484Q), the cylinder head layout differs (valve house won’t attach).

Other Haima models: Like S5, M6, or F7—different engine designs and cylinder head sizes (no functional fit).

Non-Haima vehicles: Even if similar in shape, their cylinder head specs and bolt patterns don’t match (causes leaks or valve train damage).

 Installation & Upkeep (Requires Basic Engine Knowledge)

Installation: Best Done by Mechanics (30–45 Minutes)

Replacing a valve house needs careful gasket handling—here’s the process:

Prep: Turn off the S7’s engine and let it cool (hot oil is dangerous). Open the hood, remove the engine cover (if present), and disconnect any hoses or wires attached to the old valve house.

Remove old valve house: Loosen the bolts holding the valve house to the cylinder head (use a torque wrench to avoid stripping threads). Gently lift the old valve house off—scrape away any leftover gasket material from the cylinder head (don’t scratch the surface).

Install new valve house: Place a new rubber gasket into the valve house’s groove (ensure it’s aligned). Set 484Q-10-220-T onto the cylinder head, then tighten the bolts in a crisscross pattern (follow Haima’s torque specs—over-tightening breaks the gasket).

Test: Reconnect hoses/wires and add engine oil if needed. Start the engine and check for oil leaks around the valve house (look for wet spots—if none, the installation is successful).

Maintenance: Simple Checks to Avoid Leaks

Inspect for oil leaks monthly: Look under the hood for oil stains around the valve house’s edges—leaks mean the gasket is worn (replace the gasket or valve house if damaged).

Check bolt tightness yearly: Use a torque wrench to ensure the valve house bolts are tight (vibration can loosen them—loose bolts cause leaks).

Replace gasket during oil changes: If the valve house is removed (e.g., for camshaft repairs), always install a new gasket (old gaskets lose their seal).

Avoid harsh chemicals: Don’t use abrasive cleaners on the valve house—they can damage the surface or gasket (use a damp cloth to clean dirt).

Summary: Haima S7 Valve House (484Q-10-220-T)

As Haima S7’s “engine valve protector,” this precision-sealed component is made of high-grade aluminum alloy/reinforced plastic (heat/corrosion-resistant), with a rubber gasket (airtight seal) and pre-drilled bolt holes. Mounted on the 484Q engine’s cylinder head, it’s exclusive to Haima S7 with the 484Q engine (confirm via VIN), matching cylinder head shape, gasket size, and bolt pattern.

Key roles: Shield the valve train (valves, camshafts) from debris (prevent wear/jamming); seal engine oil (avoid leaks, maintain lubrication); reduce valve train noise for quieter operation.

It fits all 484Q-engine Haima S7 variants but not S7 with other engines, other Haima models (e.g., S5, M6), or non-Haima vehicles.

Mechanic installation is recommended (30–45 mins: cool engine, gasket replacement, torque wrench use). Maintenance: Inspect for oil leaks monthly, check bolt tightness yearly, replace gasket when removing the valve house, clean with a damp cloth.

Original valve houses ensure seal integrity and engine compatibility—aftermarket ones risk leaks, heat warping, misfit bolts, or valve train interference.
