The sender measures oil pressure and converts it into an electrical signal that is displayed on the dashboard gauge. This allows the driver to monitor engine lubrication in real time - critical for engine health.

This part replaces several earlier versions including 92860620301, 92860620302, and 94460620301.

The oil pressure sender continuously monitors engine oil pressure and relays this information to the vehicle’s instrument cluster. This ensures the driver is alerted to any abnormal pressure conditions that could indicate lubrication issues.

Accurate oil pressure monitoring is essential to prevent engine damage caused by insufficient lubrication.

Function
•  Measures engine oil pressure
•  Sends signal to dashboard gauge or warning light
•  Helps monitor engine lubrication in real time
•  Alerts driver to potential oil system issues

Over time, oil pressure senders can fail due to internal wear, contamination, or electrical faults. A faulty sender may give incorrect readings or trigger warning lights unnecessarily.

Replacing a worn or failing sender ensures accurate oil pressure monitoring, helping to protect the engine from potential damage caused by low lubrication.

When to replace
•  Incorrect or fluctuating oil pressure readings
•  Oil pressure warning light activation
•  Oil leaks from sender unit
•  Electrical faults or intermittent gauge readings
•  During engine maintenance or restoration

Oil Thermostat O-Ring on Engine Case - 39.2 x 3mm
OE Match oil thermostat O-ring on engine case, 39.2 x 3mm, for Porsche 911, 914-6, 964, and 993 models. This replacement sealing O-ring helps prevent oil leaks at the engine-mounted thermostat area and supports correct engine oil system sealing.

Fits:
Porsche 911 - 1970 to 1989
Porsche 964 - 1989 to 1994
Porsche 993 - 1994 to 1997
Porsche 914-6 - 1970 to 1976

Diagram ref no 34

The O-ring seals the joint between the oil thermostat and engine case. A correctly fitted seal helps prevent oil seepage, maintain oil system integrity, and keep the engine area clean and leak-free.

Functions
• Replaces the oil thermostat O-ring
•  Seals the thermostat connection on the engine case
•  Helps prevent engine oil leaks
•  Supports correct oil system sealing
•  Suitable for oil thermostat, engine case, or oil leak repair
•  Replaces hardened, flattened, cracked, swollen, or damaged O-rings
•  OE Match replacement for Porsche engine oil system service.

Why Replace This Part?
Oil thermostat O-rings can harden, flatten, crack, swell, or lose sealing ability due to heat, age, oil exposure, and pressure cycles. A worn or damaged O-ring may allow oil seepage around the thermostat area, causing oil residue, low oil level concerns, engine bay contamination, or failed inspection. Replacement is recommended whenever the thermostat is removed or oil leakage is present.

When to Replace This Part
•  Oil is leaking around the engine-mounted thermostat area
•  The oil thermostat has been removed or serviced
•  The O-ring is hard, flattened, cracked, swollen, or damaged
•  Engine case sealing work is being carried out
•  Oil seepage or oil residue is visible around the thermostat connection
•  Preventative replacement is required during engine service

Where it fits on the car
This O-ring fits at the oil thermostat connection on the engine case. It forms part of the engine oil sealing system on Porsche 911, 914, 964, and 993 models.

About Oil Pressure Senders / Switches

Engine Oil Pressure Switches & Senders – Precision Monitoring for Porsche Engines

The engine oil pressure switch or sender unit is a vital component of your Porsche’s lubrication system. Its primary role is to monitor oil pressure and send signals to your dashboard, ensuring the engine always maintains sufficient lubrication. A properly functioning oil pressure sender safeguards against engine wear, overheating, and performance loss.

At Design911, we supply a full range of oil pressure switches and sender units for classic and modern Porsche models. Built from high-quality, heat-resistant materials, these components are designed for durability, accuracy, and consistent performance under demanding driving conditions.

Whether you’re restoring a classic 911, maintaining a Cayenne, or servicing a Cayman, our oil pressure senders and switches provide dependable pressure monitoring and peace of mind every time you drive.

What Do Oil Pressure Switches & Senders Do?

Oil pressure switches and senders work together to ensure your engine has the correct oil pressure for proper lubrication.

Core Functions:

  • Monitor oil pressure in the engine’s lubrication system.
  • Transmit readings or alerts to the vehicle’s dashboard gauge or warning light.
  • Protect engine components by warning of low oil pressure.
  • Ensure stable oil circulation during all driving conditions.

Accurate oil pressure monitoring prevents engine damage and maintains optimal performance, making these parts essential to Porsche reliability.

Why Do Oil Pressure Switches & Senders Fail?

Over time, exposure to heat, vibration, and oil contamination can cause pressure switches and sensors to deteriorate or malfunction.

Common Causes of Failure Include:

  • Oil contamination clogging internal diaphragms or ports.
  • Electrical corrosion or connector failure.
  • Seal degradation, leading to oil leaks.
  • Wear and tear from repeated heat cycles.
  • Faulty readings due to sensor fatigue or wiring damage.

Symptoms of a failing sender include flickering oil pressure lights, inaccurate gauge readings, oil leaks, or false low-pressure warnings, all of which can compromise performance or lead to unnecessary engine risk.

Why Replace Components?

A reliable oil pressure reading is crucial for the health of your Porsche engine. Replacing worn switches or senders with precision-engineered, high-quality components ensures dependable performance, accurate readings, and long-term protection.
