111-115-111B VW Oil Pump Gasket (8mm Mounting Holes) - Beetle, Ghia, Bus

VW Oil Pump to Case Gasket (8mm) – 111-115-111B

Ensure a perfect seal for your later-model air-cooled engine with this precision-fit Oil Pump Gasket. While sharing a similar base part number with earlier versions, this specific gasket is engineered for the 1500cc and 1600cc engine cases that utilize the larger 8mm mounting studs for the oil pump. It sits between the engine case and the pump flange, providing the necessary barrier to maintain high oil pressure and prevent messy external leaks.

The 111-115-111B is cut from premium gasket material designed to withstand the constant heat and chemical exposure of a Volkswagen engine bay. Because the later 1500-1600cc cases moved to a larger stud diameter, using the correct 8mm-hole gasket is vital for proper alignment. A mismatched gasket can bunch up during installation, leading to "false torque" readings on your mounting nuts or, worse, internal oil pressure cavitation.

Detailed Vehicle Compatibility This 8mm-hole gasket is typically found on 1500cc and 1600cc "Single Port" and "Dual Port" engines:

Product Highlights & Features 8mm Mounting Holes: Specifically sized for the larger studs found on 1500-1600cc engine cases, ensuring the gasket lays flat without modification.

High-Compression Seal: The treated paper construction compresses slightly under torque to fill minor imperfections in the magnesium or aluminum engine case face.

Internal Pressure Protection: Prevents the oil pump from drawing air into the system, which is essential for protecting your bearings during high-RPM driving.

Exact Restoration Spec: Maintains the factory-correct thickness required for the oil pump to sit at the proper depth relative to the camshaft drive.

Technical Specifications Part Number: 111-115-111B

Hole Size: 8mm (Large Stud)

Application: Inner Gasket (Case to Pump)

Quantity Required: 1 per Engine

Installation & Maintenance Tips Verify Your Stud Size: Before installing, quickly check if your oil pump mounting studs are 6mm or 8mm. This gasket is specifically for the 8mm studs found on the later, larger displacement engines.

Dry Installation: This gasket is designed to be installed dry. Avoid using heavy greases or silicone sealants, which can cause the gasket to "squeeze out" of place when you torque the oil pump nuts.

Inspect the Pump Flange: Ensure your oil pump flange is perfectly flat. If the pump was previously over-torqued, the flange might be slightly bowed. A flat surface is required for this gasket to do its job effectively.

Pair with Outer Gasket: Remember that this is the inner seal. Always replace the Outer Oil Pump Cover Gasket (Part # 111-115-131B) at the same time to ensure the entire pump assembly is leak-free.
