Finding a boost leak on a B58
My M240i started hissing under hard acceleration. The symptom, the checks that ruled things out, and where the leak turned out to be.
I study mechanical engineering in Riga and spent last summer working on fast cars in Istanbul. This is where I write down what I learn from both.
I'm Gokdeniz, a final-year mechanical engineering student at Riga Technical University, with hands-on workshop experience on high-performance cars.
Before engineering I studied automotive technology and computer programming, and did my first internship in a Renault dealer workshop. In the summer of 2025 I spent three months at Mekanik Garaj, working next to master mechanics on everything from daily drivers to Lamborghinis and McLarens.
At university I work in SolidWorks and ANSYS. My thesis is the structural design and topology optimization of a front upright for a Formula Student car.
Away from the desk I follow Formula 1 closely. I speak Turkish and English, and I'm looking for a design or analysis role in automotive or motorsport from April 2027.
Things I've fixed, built or simulated. The first three are being written.

Three months at Mekanik Garaj, and what it taught me about how cars wear and fail.
A textbook FEA problem that shows how much the mesh changes the stress you read.
Simulation is easier to trust when you've had the real part in your hands.
Mechanical assistant. Maintenance, repair and assembly next to master mechanics, on high-performance and everyday cars.




Looked after at Mekanik Garaj. I traced its boost leak myself; the write-up is coming in Notes.
