Documented HV 703 Engine Application
The 538676101 is specifically documented within the Husqvarna HV 703 engine.
The HV 703 cylinder-head assembly lists:
- Cylinder Head Kit – Starter Side
- Cylinder Head Kit – Breather Side
- Push Rod Kit
- Valve Stem Seal
- Tappet Kit
- Valve & Spring Kit
- Cylinder Head Shroud
- Rocker Arm Kit
- Spark Plugs
- Cylinder Head Gasket/Bolt Kit
- Exhaust Kit
- 538676101 – Valve Cover Gasket
- Valve Cover Kit
The engine documentation identifies 538676101 as LCT part SK7034301.1.
Valve Cover Gasket Function
The valve cover encloses the upper portion of the engine's valve train.
Depending on the engine configuration, this area can contain components such as:
- Rocker arms
- Valve springs
- Valves
- Push rods
- Cylinder-head oil passages
- Breather components
The 538676101 gasket creates the sealing interface between the valve cover and cylinder head.
A proper seal helps:
- Retain lubricating oil
- Reduce external oil leakage
- Keep contaminants out
- Maintain a clean valve-train environment
- Protect internal cylinder-head components
Oil Leak Prevention
A deteriorated valve cover gasket can allow engine oil to seep from the joint between the valve cover and cylinder head.
Possible leakage may appear as:
- Oil residue around the valve cover
- Wetness along the gasket seam
- Oil collecting on the cylinder head
- Dirt and debris sticking to oily surfaces
- Oil odor as leakage reaches hot engine surfaces
Replacing the gasket can restore the sealing surface when gasket deterioration is the cause of the leak.
Common Reasons for Replacement
Replacement of the 538676101 Valve Cover Gasket may be appropriate if the original gasket has:
- Torn
- Cracked
- Hardened
- Become brittle
- Become compressed
- Developed permanent deformation
- Sustained heat damage
- Been damaged during valve-cover removal
- Developed an oil leak
- Become contaminated
- Failed to reseal after engine service
- Become unsuitable for reuse
Valve-cover gaskets are sealing components and may require replacement whenever the valve cover is removed for internal engine service.
Possible Signs of Valve Cover Gasket Failure
A damaged or deteriorated gasket may contribute to:
- Oil leaking around the valve cover
- Oil seepage along the cylinder head
- Oily engine surfaces
- Accumulation of dirt around the gasket joint
- Oil odor during operation
- Visible gasket deterioration
- Contamination around the valve-train area
These symptoms can also result from a damaged valve cover, loose fasteners, excessive crankcase pressure, or other engine sealing problems.
Valve Cover Inspection
When replacing 538676101, inspect the valve cover for:
- Cracks
- Warping
- Damaged sealing surfaces
- Impact damage
- Corrosion
- Distorted mounting points
- Damaged fastener holes
Husqvarna's HV 703 documentation separately identifies a valve cover kit for the engine, confirming that the gasket and valve cover are distinct service components.
Cylinder Head Inspection
Inspect the mating surface on the cylinder head for:
- Old gasket material
- Oil residue
- Dirt
- Scratches
- Corrosion
- Damage
- Uneven sealing surfaces
Both mating surfaces should be appropriately prepared according to the engine service procedure before installing the replacement gasket.
Related HV 703 Gasket Components
The HV 703 engine documentation lists several related sealing components:
- 538675901 – Engine Gasket, Seal & O-Ring Kit
- 538676001 – Cylinder Head Gasket/Bolts
- 538676101 – Valve Cover Gasket
- 538676701 – Crankshaft Oil Seal Kit
This confirms that 538676101 is specifically the valve-cover gasket, rather than the cylinder-head gasket or a complete engine gasket kit.
Installation Considerations
A typical valve-cover gasket replacement involves:
- Shut off the engine.
- Remove the ignition key where applicable.
- Allow the engine to cool completely.
- Disconnect the spark plug or battery as appropriate.
- Remove components obstructing access to the valve cover.
- Remove the valve-cover fasteners.
- Carefully remove the valve cover.
- Remove the old gasket.
- Clean the valve-cover and cylinder-head sealing surfaces.
- Inspect both mating surfaces for damage.
- Position the new 538676101 gasket correctly.
- Reinstall the valve cover.
- Tighten the fasteners according to the applicable engine specification.
- Reassemble any removed components.
- Run the engine and inspect the valve-cover area for leakage.

- Inspect the valve cover for warping or damage before installing a new gasket.
- Clean the mating surfaces before installation.
- Avoid scratching or gouging the cylinder-head sealing surface when removing old gasket material.
- Do not overtighten valve-cover fasteners, as excessive force may distort the cover or damage the gasket.
- Follow the applicable LCT/Husqvarna torque specification when available.
- Do not automatically apply RTV, silicone, gasket cement, or another sealant unless specified by the applicable engine service procedure.
- Inspect the engine after installation for oil seepage.
- If leakage continues with a new gasket installed, inspect the valve cover, mating surfaces, fasteners, and crankcase ventilation system.
- Allow the engine and exhaust components to cool before performing service.
- Disconnect the spark plug or battery as appropriate before accessing engine components.
