Ultimate Guide: Replacing Briggs & Stratton OHV Head Gasket
Introduction
The head gasket, located between the engine block and the cylinder head, plays a crucial role in sealing the combustion chamber and preventing coolant and oil leaks. Replacing a head gasket on a Briggs & Stratton OHV engine can be a daunting task, but with the right tools and guidance, it's a manageable endeavor. This comprehensive guide will walk you through the process step-by-step, empowering you to restore your engine to optimal performance.
How to Change Head Gasket on Briggs & Stratton OHV
Step 1: Safety First
Before commencing any work, ensure your safety by disconnecting the spark plug wire and allowing the engine to cool completely.
Step 2: Removal of Valve Cover
Locate the valve cover on the cylinder head and remove the bolts securing it. Carefully lift the valve cover, observing the condition of the gasket beneath.
Step 3: TDC Alignment
Rotate the engine crankshaft until the piston in the cylinder being worked on is at its highest point (Top Dead Center). This ensures the valves are fully closed.
Step 4: Head Bolts Removal
Locate the head bolts on the cylinder head and loosen them in a crisscross pattern. Gradually loosen the bolts until hand-tight, then remove them completely.
Step 5: Head Gasket Removal
Carefully lift the cylinder head off the engine block. Inspect the old head gasket for any signs of wear or damage.

Step 1: Cleaning Surfaces
Thoroughly clean the mating surfaces of the cylinder block and cylinder head using a gasket scraper and solvent. Ensure there is no dirt or debris that could compromise the seal.
Step 2: Head Gasket Installation
Position the new head gasket on the cylinder block, ensuring it is aligned correctly. Use a thin layer of gasket sealant to enhance the seal.
Step 3: Cylinder Head Reinstallation
Carefully lower the cylinder head onto the cylinder block. Secure the head bolts hand-tight, then tighten them gradually in a crisscross pattern to the specified torque.
Step 4: Valve Cover Replacement
Reinstall the valve cover, using a new gasket if necessary. Tighten the valve cover bolts to the recommended torque.
Step 5: Finishing Touches
Connect the spark plug wire and fill the engine with clean oil and coolant. Start the engine and allow it to run for a few minutes. Check for any leaks or unusual noises.
