Zakład Mechaniczny Janusz Łukasiewicz, known across Europe under the “JŁ Łukasiewicz” brand, is a Polish manufacturer specializing in high-precision valve guides and semi-finished bushings for internal combustion engine reconditioning. Operating for over 40 years, the company leverages specialized cast iron and bronze alloys to deliver both standard catalogue references and short-run, reverse-engineered custom components.
A brief description of the company and its activities.
Zakład Mechaniczny Janusz Łukasiewicz is a Polish manufacturer of components for internal combustion engine reconditioning. To our clients, we are known under the “JŁ Łukasiewicz” brand. For over 40 years, we have specialized in traditional, high-precision manufacturing of valve guides and semi-finished products for further machining. Our experience allows us to instantly supply cylinder head reconditioning workshops with top-quality parts exclusively.
What are the main areas of activity of the company?
Our core business includes: machining components using specialized cast iron and bronze alloys, reverse engineering and short-run production of non-standard parts, as well as direct deliveries and technical cooperation with engine reconditioning shops across Europe.
What’s the news about new products/services?
We systematically expand our catalogue to cover specialized and industrial engines (including references for Steyr engines) as well as passenger cars (e.g., 1.3 TCi engines or the increasingly imported large-displacement US V8 HEMIs). We continuously monitor market demand for valve guides for newer vehicles, steadily adding new items to our catalogue as a result. We have also standardized our manufacturing process based on physical samples supplied by customers. We will present our manufacturing capabilities at the Automechanika Frankfurt 2026 trade fair (Hall 5.0, Stand A68).
What are the ranges of products/services?
Our portfolio includes an extensive catalogue of valve guides, both standard and oversized (made of cast iron and bronze), as well as semi-finished bushings with a pre-drilled bore for custom machining. Additionally, we offer modification services for existing catalogue guides to meet individual customer requirements, along with custom production based on technical drawings or physical samples. We also successfully manufacture valve guides for motorsport, where material quality and precision engineering are paramount.
What is the state of the market where you are currently active?
We consider the European engine reconditioning market to be stable. Driven by the increasing average age of vehicle fleets and the cost-effectiveness of repairs compared to complete engine replacements, there remains a steady demand for precision-machined spare parts from reliable regional suppliers.
What can you tell us about market trends?
We observe a localization of supply chains (workshops prefer European manufacturers for speed and quality), declining availability of OEM parts for older engines (which drives the market for specialized aftermarket manufacturers), and stricter material requirements forced by higher operating temperatures in modern engines.
What are the most innovative products/services marketed?
From a B2B perspective, our key advantage lies in our optimized order fulfilment process for custom solutions. We can swiftly transition from measuring a provided sample to producing a short run of custom guides or valve seats, significantly reducing repair times and minimizing machinery downtime for the end customer. We also maintain continuous contact with workshops in Poland and abroad, actively analysing their needs. A prime example is our addition of several guide references with reduced or enlarged bores to our catalogue (including guides for Volkswagen and Fiat). This provides clients with greater flexibility, allowing them to select the right valve guides depending on whether they use new or reconditioned valves during repair. Utilizing the appropriate guide eliminates the need for reaming, making work with our product faster and more convenient.
What estimations do you have for the second half of 2026?
In the second half of 2026, we expect steady growth in order volumes. We will focus on strengthening our European B2B network following the Automechanika Frankfurt trade fair and gradually adding further specialized part numbers to our standard offering.
