The dipstick assembly is precision‑stamped with clear “FULL” and “ADD” marks, allowing quick and accurate oil level checks even in low‑light conditions. Its handle is ergonomically designed for a secure grip, and the blade is coated to resist corrosion and wear.

The dipstick pipe below set is manufactured from seamless steel tubing with a corrosion‑resistant finish, ensuring a smooth, consistent internal bore for the dipstick. Its precise bend angle and length are matched to the WP12 oil pan, providing accurate oil level readings.

The back‑up block is a reinforced steel bracket that provides additional support to the dipstick tube, preventing flexure and maintaining correct alignment. Its robust design ensures the tube remains securely attached to the engine block, even under high vibration.

The pipe clamp assembly and single pipe clamp are manufactured from spring steel with a zinc‑plated finish, providing a secure grip on the dipstick tube without damaging the surface. Their design allows for easy installation and adjustment, ensuring the tube is held firmly in place.

The hexagon flange bolt is grade 10.9 with a pre‑applied thread‑locking compound, providing reliable attachment of the dipstick tube bracket to the engine block. Its flange design distributes load evenly, preventing loosening and ensuring long‑term retention.

Dipstick Assembly – The complete oil level measuring tool, consisting of a stamped steel handle and a flexible blade with calibrated marks. The handle is designed for a secure grip, even with oily hands, and the blade is precision‑marked with “FULL” and “ADD” levels, allowing accurate oil level checks without removing the dipstick. The blade is coated to resist corrosion and is flexible enough to follow the curved pipe without binding. This assembly provides a reliable, repeatable measurement of oil level, critical for maintaining proper engine lubrication. Its easy‑to‑read markings help prevent overfilling or underfilling, extending engine life and reducing oil consumption. This assembly is a direct replacement for the original factory component, ensuring consistent accuracy and durability.

Back‑up Block – A reinforced steel bracket that provides additional support to the dipstick tube, preventing excessive movement and vibration. Manufactured from high‑strength steel with a corrosion‑resistant coating, this block is bolted to the engine block and securely clamps the dipstick tube in place. Its rigid design reduces stress on the tube and pipe connections, preventing fatigue cracks and oil leaks. The back‑up block also ensures that the dipstick tube remains correctly aligned, allowing the dipstick to be inserted and withdrawn smoothly without binding. This component is essential for long‑term reliability, especially in high‑vibration applications, and should be inspected for tightness during routine maintenance.

Pipe Clamp Assembly – A pre‑assembled clamping unit consisting of a spring‑steel band and a locking screw, designed to secure the dipstick tube to the engine block or other brackets. The clamp provides a firm, vibration‑resistant grip that prevents the tube from moving or chafing. Its zinc‑plated finish resists corrosion, and the screw allows for easy installation and adjustment. The clamp’s design distributes clamping force evenly, preventing deformation of the tube. This assembly is critical for keeping the dipstick tube in its correct position, ensuring accurate oil level readings and preventing damage to the tube or surrounding components. Replacement is recommended if the clamp loses its tension or shows signs of corrosion.

Hexagon Flange Bolt – A high‑strength fastener with an integrated flange, used to secure the dipstick tube bracket or back‑up block to the engine block. Manufactured from alloy steel, heat‑treated to grade 10.9, and coated with a zinc‑flame finish, this bolt provides reliable clamping force under high vibration and thermal cycling. The flange distributes load evenly, preventing galling and ensuring consistent torque retention. It is supplied with a pre‑applied thread‑locking compound to prevent loosening. This bolt is a critical component for maintaining the integrity of the dipstick tube mounting, and should always be replaced with a new one during any service that involves removing the dipstick tube.

Rubber Hoop – A flexible elastomeric ring that provides a cushion and seal between the dipstick tube and the engine block or bracket. Manufactured from high‑temperature oil‑resistant rubber (NBR or FKM), this hoop absorbs vibration and compensates for minor misalignments, reducing stress on the tube and preventing metal‑to‑metal contact. Its resilient material also helps to prevent oil seepage around the tube entry point. The rubber hoop is easy to install and is a cost‑effective solution for reducing noise and extending the life of the dipstick tube. Inspection for cracking or hardening is recommended during routine service, and replacement is advised if any signs of deterioration are found.

Single Pipe Clamp – A simple yet robust spring‑steel clamp used to secure the dipstick tube to a fixed bracket or the engine block. Featuring a single‑piece design with a tensioning screw, this clamp provides a secure grip on the tube while allowing easy adjustment. Its zinc‑plated finish resists corrosion, and its narrow profile fits in tight spaces. The clamp is designed to maintain consistent pressure on the tube, preventing movement while not over‑compressing the tube. This clamp is essential for keeping the dipstick tube routed correctly and preventing chafing against other components. It should be checked for tightness during regular maintenance.

Dipstick Pipe Below Set – The lower portion of the dipstick tube assembly, consisting of a precision‑bent steel pipe that extends from the engine block into the oil pan. Manufactured from seamless steel tubing with a corrosion‑resistant coating, this pipe provides a smooth, continuous bore for the dipstick. Its precise bend angle and length are matched to the WP12 oil pan geometry, ensuring that the dipstick reaches the correct oil level and provides accurate readings. The pipe includes a mounting flange or bracket for secure attachment to the engine block. This set is a direct replacement for the original pipe and is essential for maintaining accurate oil level measurement and preventing leaks. Replacement is recommended if the pipe is damaged, corroded, or if the sealing O‑ring at the block interface is worn.
