Engine Cleaning

We can clean virtually any engine part as long as it is completely stripped down and sensitive areas are masked. Whether we use plastic, garnet, glass bead or vapour blast media very much depends on what we are taking off and what the engine part is made from, i.e. hard steel, mild steel, aluminium, etc.

We have cleaned whole engines, like the very rare Merlin engine from a Spitfire, all 26 litres of it.

 With any engine part that comes into contact with the oil we normally only clean with our plastic material, because it does not dig into the surface of the metal like grit could. If a tiny particle of grit were to dislodge from its location embedded in the metalwork of a sump say, it then could travel around in the engine with potentially damaging results, even though it is only microns in size. Using only plastic media inside the engine reduced this problem dramatically because it is not hard enough to dig into the metal and it is a soft material anyway, it would break down into dust unlike a bit of grit which could become a grinding paste.

Plastic media is capable of removing all the sealing compound and a lot of oily deposits and carbon residues. It is great for de-carbonising heads and ports etc..

On the outside of the engine we can use a range of materials and sometimes a combination of processes.

Often, customers want to clean the surfaces of their old engines but they want to retain the patena of use, they don’t want every little mark removed to make it look like a new pin, it needs to look clean but used. We work hard to achieve that look.
