Summary We're looking for an experienced mechanical engineer or product designer to develop a production-ready aluminum oil catch can for a diesel engine platform. This is not a reverse-engineering project. We're not looking to copy an existing design - we're developing our own product with our own internal architecture. This is also not a cosmetic CAD job. We need someone who understands mechanical design, manufacturability, machining, sealing, and fluid dynamics, and can turn those concepts into a production-ready product. Important I am a professional mechanic with 15 years of experience working on these engines. I do not need someone to engineer the complete PCV system or determine hose routing, mounting location, etc. I already know how the system should be installed, how it will be mounted, and how it integrates with the engine. I am looking for someone to engineer and design the oil catch can itself - its internal architecture, manufacturability, sealing, and production-ready CAD. Project Scope Design a premium, filterless aluminum oil catch can that includes: 6061 aluminum body Threaded top cap with O-ring seal Multi-stage internal oil separation using vortex flow and baffles (no filter media) External oil level sight tube Bottom drain Mounting interface for our vehicle-specific bracket (mounting bracket and installation layout are not part of this project) Complete production-ready CAD model Manufacturing drawings for CNC machining The design must be effective, reliable, practical to manufacture, and easy to assemble. Deliverables Complete 3D CAD assembly Individual part files 2D manufacturing drawings with tolerances Exploded assembly Bill of Materials (BOM) STEP files Native CAD files (SolidWorks preferred) Requirements You should have experience with: Automotive components CNC-machined aluminum parts Threaded assemblies and O-ring sealing Design for Manufacturing (DFM) Production-ready mechanical design Experience with oil separators, PCV systems, fluid handling, pressure vessels, or similar products is a major advantage. When applying, please include: Examples of similar mechanical products you've designed Products that have actually been manufactured (not just renders or concept models) The CAD software you use Your estimated timeline Your fixed-price quote A brief explanation of how you would approach the internal oil separation design Requirement We are not looking for someone to learn on this project. We don't have the time or desire to train a designer at our expense. If your experience is primarily consumer products, hobby-level CAD, 3D printing, or basic modeling without real engineering experience, this project is probably not a good fit. We're looking for someone who thinks like an engineer, challenges assumptions when appropriate, and can deliver a design that's ready for manufacturing. Location Requirement You must be physically located in the United States. We are not looking for offshore contractors, agencies, or freelancers working from another country while presenting themselves as US-based. If your profile lists the United States but you are actually located elsewhere, please do not apply. We verify location during the interview process. Budget We're looking for excellent engineering at a realistic budget, with the opportunity for a long-term working relationship on future automotive products. If your typical project budget starts at $5,000–10,000+, we're probably not the right fit for this project. Let's value each other's time and build a strong, long-term working relationship.

Hi, Your project aligns closely with my expertise in mechanical design, CNC-machined products, and Design for Manufacturing (DFM). I have extensive experience developing production-ready mechanical assemblies using SolidWorks, with a strong focus on manufacturability, sealing, tolerance analysis, and assembly optimization. Rather than reverse-engineering an existing product, I will develop a robust oil catch can around your functional requirements. The design will incorporate a CNC-friendly 6061 aluminum body, threaded cap with O-ring sealing, multi-stage filterless oil separation using vortex flow and baffles, external sight tube, bottom drain, and an assembly optimized for reliability, serviceability, and cost-effective manufacturing. Deliverables include: - Complete 3D CAD assembly and part files - Native SolidWorks and STEP files - Manufacturing drawings with GD&T - Exploded assembly and BOM - Production-ready CNC documentation My design approach emphasizes efficient oil separation with minimal pressure drop while ensuring simple machining, reliable sealing, and easy assembly. Throughout the project, I will provide engineering recommendations to improve manufacturability and long-term product performance. I am confident I can deliver a high-quality, production-ready design and would welcome the opportunity to discuss your requirements in detail. Best regards,

Hi, there! Thank you for the clear and detailed project description. I understand you’re looking for an experienced mechanical engineer with a strong background in production-ready design—specifically for a purpose-built, filterless aluminum oil catch can designed for manufacturability and performance, not a cosmetic or copycat solution. My experience includes engineering OEM and aftermarket automotive components, particularly CNC-machined aluminum assemblies and oil/air separation systems. I am well-versed in DFM, threaded assemblies, O-ring sealing, and have successfully delivered similar components from concept through manufacturing. For your project, my approach will include: - Review and analysis of your requirements, installation interface, and mounting needs - Engineering evaluation for internal oil separation—optimizing vortex flow and baffle placement - Preparing detailed 3D CAD, manufacturing drawings, assembly documentation, and BOM - Collaboration and support throughout the review and approval process If you can provide any existing sketches, dimensional constraints, preferred connections, or specific installation requirements, please share them to ensure all needs are addressed from the start. Best regards.

Most of my design experience is with manufacturing equipment, not automotive parts. I have 15 years of experience designing systems that are fabricated and used in manufacturing facilities. If there is still interest in learning more about my experience, I'd be happy to chat more for clarity. I can also offer a consulting partnership for drafting and fabrication if you find someone with automotive experience without design for manufacturing experience. The budget is very reasonable if the design concept and internals are already known, and the only need is to have a professional take the sketches and ideas and turn them into models ready for manufacture. This scope would not include in-depth engineering such as simulations. If this project is to develop a machined assembly to test and use as a starting point for future development on a personal or business vehicle, a quick turnaround could be 2-3 weeks. If the goal is to have production volume for consumer sales, I'd suggest more development time to ensure the reliability and safety of the part. Additionally, intended production volume or price target would greatly influence how parts are designed and fabricated. This process would be a lot longer with higher design costs. My fluid dynamics and flow analysis within SolidWorks or other simulation software is limited, so if that is a desired requirement, going with a professional that has this specialty would be more economical for your project, as I would outsource.
