This week I had my first chance to strip down an engine by hand, an old road car engine that Mark was going to turn into a race engine. He gave me the task of fully stripping it down to the bare block. It’s something I’d wanted to do for a long time but never had the chance.
As a driver, an engine is usually abstract. You know it exists, you understand the basics of how it works, but you rarely ever see it fully exposed or learn how each component comes apart and fits together. Until you take an engine from a complete unit down to a bare block, you don’t fully appreciate how it operates or the precision hidden inside.
What struck me wasn’t complexity, but order.
The way every component has a defined role and works in synchrony with everything else. Once the head comes off and the valves, pushrods and internal components are exposed, you start to see how intricate the system really is. From the outside, an engine is just a heavy block that produces noise and power. Inside, it is a carefully arranged system where nothing is accidental.
The biggest surprise was how quickly the mystery disappeared.
Parts I had heard discussed for years suddenly became tangible. Bearing wear was no longer a phrase I heard in the workshop. It was something I was holding in my hand. Components that had always felt hidden inside the engine were now sitting on the bench in front of me.
Working further down into the engine, removing the sump reveals the crankshaft, conrods and camshaft. Each part is secured with specific bolts and clear placement, all designed so the engine can operate smoothly at high speed and load. At that point, the mystery of the engine is replaced by curiosity and focus.
As I removed each component, I noticed wear patterns that told a story. Marks on surfaces showed stress, load and time passing through the engine. It became physical evidence of how it had been driven, and how mechanical sympathy—or the lack of it—affects longevity. Poor maintenance and abuse leave their mark clearly once everything is exposed.
Looking at the bearings and journals, I found myself thinking about all the forces moving through the engine every time the car leaves the pits. The loads are enormous, yet each component is expected to perform its role perfectly every lap.
Formula Ford follows a similar philosophy. On the surface it is simple: no wings, no slicks, a basic H-pattern gearbox. That simplicity continues into the engine design. The crossflow unit is stripped of unnecessary complexity, relying on fundamentals rather than electronics or modern systems. Pistons, conrods, crankshaft, valves—everything essential, nothing extra.
It reflects the nature of Formula Ford as a driver’s category, where skill matters more than technology.
By the time the crankshaft was sitting on the bench and the block was empty, I found myself looking back at what had become a collection of individual parts. Every component looked relatively simple on its own, yet without every single one doing its job perfectly, the engine stops being an engine.
Ultimately, understanding an engine at this level changes how you see it.
Before stripping it down, I respected what the engine could do.
Afterwards, I respected what it has to go through to do it.
Every lap, every gear change and every race weekend leaves its mark somewhere inside. Seeing those marks first hand gave me a much greater appreciation for the engine, the people who build them and the responsibility of looking after them.
The engine stopped being a noisy box at the back of the car and became something else entirely.
A precise mechanical system where every part matters.
