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

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.

The push rod tube seal helps create a leak-free seal around the push rod tube where it fits into the engine case or cylinder head area. A good seal helps prevent engine oil leaks and supports clean, reliable operation of the valve train and crankcase sealing system.

Functions
• Replaces the push rod tube seal
•  Helps seal the push rod tube connection
•  Helps prevent engine oil leaks
•  Supports correct valve train and crankcase sealing
•  Suitable for push rod tube removal, refitting, or replacement
•  Replaces flattened, hardened, cracked, split, or leaking original seals
•  OE Match replacement for Porsche 914 engine repair and maintenance.

Why Replace This Part?
Push rod tube seals are exposed to heat, oil, engine vibration, and age-related wear. Over time, the rubber can harden, flatten, crack, or lose its sealing ability. A failed seal may cause oil leaks around the push rod tube area, oil staining on the engine, burning oil smells, or oil dripping onto hot components. Replacing the seal helps restore a clean, reliable engine oil seal.

When to Replace This Part
•  Oil leaks are visible around the push rod tubes
•  The seal is hard, cracked, flattened, split, or damaged
•  Push rod tubes are being removed or replaced
•  Cylinder head, valve train, or engine sealing work is being carried out
•  Oil staining or drips are present underneath the engine
•  The engine is being rebuilt, resealed, or restored
•  Preventative replacement is being carried out during engine service.

Where it fits on the car
This seal fits at the push rod tube connection on Porsche 914 engines. It forms part of the engine sealing system around the push rod tube.

Push Rod Tube Seal, 21.3mm.
The Porsche Push Rod Tube Seal, 21.3mm is a replacement engine sealing component designed to fit around the push rod tube and help prevent engine oil from escaping. Manufactured as a replacement for part reference 021109345A, it is suitable for use when servicing or rebuilding compatible Porsche air-cooled engines.

Fits:

Diagram Ref No 6

Push rod tube seals are exposed to constant engine heat, oil, vibration, and repeated heating and cooling cycles. Over time, the original seal can harden, shrink, flatten, or crack, resulting in oil leaks around the push rod tube. Replacing the seal restores the joint between the tube and engine casing and helps keep the engine clean and properly sealed.  

What This Product Does:

• Seals the connection between the push rod tube and the engine.
• Helps prevent engine oil from leaking around the tube.
• Allows the push rod tube to accommodate normal engine expansion and movement.
• Protects surrounding engine components from oil contamination.
• Helps maintain the correct engine oil level.
• Supports a clean and reliable air-cooled engine installation.
• Provides a replacement for a hardened, damaged, or leaking original seal.

Symptoms Of Wear Or Failure:

• Oil leaking from around the push rod tubes.
• Oil collecting on the underside of the engine.
• Drops or patches of oil beneath the parked vehicle.
• A burning-oil smell while driving.
• Smoke caused by oil reaching hot exhaust components.
• Greasy dirt and debris accumulating around the engine.
• A gradual reduction in the engine oil level.
• A seal that appears hardened, flattened, split, or brittle.
• Oil contamination on nearby hoses, wiring, or engine components.
• Increased oil leakage after the engine reaches operating temperature.

Why Replacement Matters:

• A leaking push rod tube seal may initially appear to be a minor issue, but continued oil loss can create larger maintenance and safety concerns. Escaping oil can spread across the engine, attract dirt, damage nearby rubber components, and make it more difficult to identify other leaks.
• Oil reaching hot exhaust parts may produce unpleasant smells or visible smoke. In more serious cases, significant oil contamination around hot components may increase the risk of fire.
