Porsche 944 & 924S Crankshaft Oil Scraper – Improved Oil Control & Engine Stability Upgrade
This unique crankshaft oil scraper is designed to improve
oil control, reduce rotating drag and increase engine reliability in Porsche
924S, 944 and 944S models.
Fits:
- Porsche 924S 2.5L 1986-87
- Porsche 924S 2.5L 1988
- Porsche 944 2.5L 8V 1982-87

In high-revving engines, the crankshaft spins through engine oil at great speed. As it rotates, it throws oil outward, creating a dense cloud of oil mist around the crank assembly. This phenomenon increases rotating resistance, aerates the oil and reduces the amount of usable oil retained in the sump.
Our precision-engineered crank scraper directly removes excess oil from the crank cheeks on every rotation. The result is improved oil control, reduced drag and enhanced engine stability.
What This Crankshaft Oil Scraper Does
Reduces Rotational Drag
By scraping excess oil from the crankshaft during rotation, the scraper reduces
the weight of the crankshaft in wet running conditions. Less oil clinging to
the rotating assembly means smoother, freer revving performance.
Improves Oil Retention in the Sump
Instead of being whipped into suspension, more oil remains in the crankcase
where it belongs. This ensures a more stable oil supply under acceleration and
high RPM use.
Reduces Oil Foaming and Aeration
Excessive oil mist leads to foaming, which can reduce lubrication efficiency.
By controlling oil splash, this scraper helps maintain more consistent oil
density and lubrication quality.
Helps Prevent Oil Starvation
During hard cornering, braking or high-speed driving, oil starvation can occur
when insufficient oil reaches the suction pipe. By keeping more oil properly
settled in the sump and reducing aeration, the risk of oil starvation is
significantly reduced.
Increases Crankshaft Frame Stiffness
This component also adds structural rigidity to the crankshaft frame assembly.
When installed, the rings under the crankshaft frame nuts are omitted,
contributing to a more direct and stable mounting setup.
Precision Fitment
We have measured tolerances on used engines with maximum axial play to ensure
accurate fitment across engine conditions. The design also allows compatibility
with our H-beam connecting rods, making it ideal for performance builds and
engine rebuild projects.
Ideal for Performance and Track Use
High RPM and track conditions amplify oil aeration and starvation risks. This
upgrade provides additional protection for engines operating under stress.
Engine Rebuild Enhancement
If you are rebuilding a Porsche 944 or 924S engine, installing a crank scraper
is a smart preventative upgrade that improves long-term reliability.
Improved Engine Efficiency
Reducing oil drag on the crankshaft can contribute to smoother power delivery
and improved engine response.
Long-Term Engine Protection
By minimising oil foaming and maintaining stable oil supply to the pickup pipe,
this component supports bearing longevity and overall engine durability.
If you are building, restoring or upgrading a Porsche 924S or 944 engine, this crankshaft oil scraper is a proven solution to improve oil control, reduce drag and enhance engine stability under demanding conditions.

A magnetic sump oil drain plug is a type of oil drain plug that contains a small magnet designed to attract and capture metallic particles that may be present in your engine's oil. While this type of drain plug is not exclusive to Porsche and can be used in various vehicles, it can provide several benefits, including:
Improved Engine Longevity: The magnet in the drain plug helps to capture tiny metal particles, such as iron, steel, or aluminum, that may circulate in the engine oil. Removing these particles can reduce wear and tear on engine components, potentially extending the engine's lifespan.
Enhanced Engine Performance: By reducing the presence of contaminants in the oil, a magnetic drain plug can help maintain the oil's lubricating properties, which is crucial for smooth engine operation. Clean oil can also contribute to improved fuel efficiency.
Early Detection of Problems: As the magnetic drain plug collects metallic debris, it can serve as an early warning system. By inspecting the drain plug during oil changes, you can get an idea of the engine's condition and detect any unusual wear or damage before it becomes a major issue.
Reduced Maintenance Costs: Regularly inspecting and cleaning a magnetic drain plug can prevent larger issues from developing over time. Addressing potential problems early can save you money on more extensive repairs down the road.
Peace of Mind: Knowing that you are taking steps to protect your engine from premature wear and tear can give you peace of mind as a vehicle owner. It's a relatively inexpensive and simple modification that can provide added assurance.
Easy Installation: Magnetic drain plugs are typically straightforward to install. They often replace the existing drain plug and require no special tools or modifications.
While magnetic drain plugs can offer these benefits, it's essential to remember that they are not a substitute for regular oil changes and proper maintenance. Regular oil changes with the appropriate oil and filter are still crucial for the health and longevity of your engine. Additionally, magnetic drain plugs may not capture all types of contaminants, so they should be seen as a supplementary measure rather than a comprehensive solution.
