Diagram ref no 42

The sump plug washer sits between the engine oil drain plug and the sump opening. When the drain plug is tightened during an oil change, the washer compresses slightly to form a tight seal, preventing oil from leaking around the drain plug threads.

Replacing the washer during service helps ensure proper sealing and protects the engine from oil loss.

Fitment / Position on Car
• Fitting position: Engine oil sump drain plug
• Location: Between the drain plug head and sump housing
• System: Engine lubrication system

Drain plug washers are designed to compress once during tightening to form a proper seal. Reusing old washers can lead to oil seepage or incomplete sealing, which may result in oil loss or contamination of surrounding components. Installing a new genuine Porsche washer during each oil service ensures a clean, leak-free seal and reliable engine lubrication.

The sump plate forms the base of the engine’s oil sump, helping to contain and channel oil that has passed through the engine before it is drawn up again by the oil pump. It contributes to proper oil retention, distribution, and structural support for the lower part of the engine’s lubrication system. Without this plate, oil could escape or fail to be delivered reliably to internal engine components.

Installed at the bottom of the engine block, the sump plate either supports or replaces the original metal surface that captures oil returning to the sump and often integrates or supports features such as oil drain plug provision (depending on variant). It ensures that the engine’s lubricating oil system maintains proper capacity and seal integrity, preventing leaks and helping to sustain stable oil flow under a range of operating conditions.

The sump plate plays a vital role in the engine lubrication system. Over time, original plates can be damaged by corrosion, impact, or wear and may not seal as effectively. A compromised sump plate can lead to:
• Oil leaks at the bottom of the engine
• Reduced oil capacity or poor oil return
• Increased risk of engine wear or damage due to insufficient lubrication.

Replacing ensures proper oil containment and system integrity, helping preserve reliability and keep your classic Porsche engine performing as intended.

Replace the sump plate if you notice:
• Visible oil leaks under the engine
• A sump or plate that is bent, corroded, or damaged
• During engine overhaul or oil system servicing
• When planning long-term reliability for classic restoration
• If the original plate fails to seal properly

Push Rod Tube, Stainless Steel.
Restore dependable pushrod protection and engine oil containment with this OE Match Stainless Steel Push Rod Tube, reference 021109335C/2. Designed for compatible engine applications, the push rod tube provides a protective passage for the pushrod as it operates between the internal valve-train components, while also helping keep engine oil contained within the engine.

Fits:

• Porsche 914 1.7L, 1.8L & 2.0L 1970-76 & Type 4

Diagram Ref No 4

Push rod tubes are an important feature of pushrod-operated engines. The pushrods move continuously as the engine runs, transferring camshaft and lifter movement to the rocker assemblies that operate the intake and exhaust valves. The tubes surround the pushrods and isolate them from the external environment while allowing lubricating oil from the valve-train area to remain contained and return through the engine as intended.  

What This Product Does:

• Provides a protected passage for the engine pushrod.
• Allows the pushrod to operate freely between the lifter and rocker assembly.
• Helps contain lubricating oil within the engine.
• Supports the return of valve-train oil through the engine.
• Helps protect the pushrod from dirt, moisture, and external contamination.
• Works with the push rod tube seals to prevent oil leakage.
• Features stainless steel construction for improved corrosion resistance.
• Withstands repeated engine heating and cooling cycles.
• Helps keep the exterior of the engine clean and dry.
• Replaces a corroded, damaged, distorted, or leaking push rod tube.
• Provides an OE-style solution for compatible engine repairs and rebuilds.

Symptoms Of Wear Or Failure:

• Engine oil leaking around the push rod tubes.
• Oil collecting underneath the engine.
• Wet or oily areas around the cylinder heads or crankcase.
• Burning-oil smells while driving.
• Smoke caused by leaked oil reaching hot exhaust components.
• Dirt and debris accumulating on oil-covered engine surfaces.
• Visible corrosion or rust on existing push rod tubes.
• Dents, cracks, distortion, or other physical tube damage.
• Persistent oil leakage despite replacement of the push rod tube seals.
• Damaged sealing surfaces at either end of the tube.

Why Replacement Matters:

• Push rod tubes perform an important oil-containment function within the engine. A corroded, cracked, distorted, or damaged tube may allow engine oil to escape, resulting in an increasingly messy and potentially significant oil leak.
• Oil leaking from the push rod tube area can spread across the underside of the engine and surrounding components. If it reaches hot exhaust surfaces, it may produce smoke and a strong burning-oil smell. Continued leakage can also gradually lower the engine oil level, making regular monitoring and topping-up necessary.
• Maintaining the correct oil level is essential for protecting bearings, crankshaft journals, camshaft components, pistons, and the rest of the engine's lubricated internal parts. Allowing an oil leak to continue unchecked can therefore contribute to more serious lubrication problems.
• Corroded or damaged tubes can also prevent new seals from seating correctly. In these situations, replacing only the seals may not permanently cure the leak because the tube's sealing surfaces are no longer suitable.
