Virtual Workshop Tour

At Galloway Engines, we believe quality machining can only be achieved on quality machines.  That's why over the past 25 years we have had a continuous equipment update policy to ensure we are at the forefront of engine machining technology.

Although our policy can be expensive, it runs in line with our desire to be the best and ensures our customers get the best engine machining available.

Take a look at some of our machines....


  Our Serdi 3.0 valve seat machine is highly regarded as the most accurate for precision valve seat machining from 4mm guide diameter up to 12mm guide diameter & 3.5” seat diameter.


The Newclear Pressure Tester is a revolutionary machine that has the ability to test for cracks and defects in cylinder heads and blocks.  Pressurised water is flowed through the casting to simulate operating conditions.  The inline heater system allows hot and cold hydraulic testing, in addition to air testing, at capabilities up to 800kPa.



The Rottler VR7 Valve Refacing Machine sets new standards in speed and accuracy for cylinder head work.

Valve refacing is carried out to improve the seal between the valve and the valve seat on the head, which ensures sufficient pressure in the combustion chamber when the cylinder ignites.

The Rottler VR7 is capable of grinding small and large valves, grinding and chamfering stem ends and rocker arm grinding.


Diamond facing of cylinder heads up to 1.5m in length.




Our Rottler F67A CNC Machine is a state-of-the-art CNC Machining Centre, specifically designed for high performance blueprinting operations.

The Rottler F67A CNC Machine blueprinting capabilities include operations such as deck squaring to the main and cam centreline, boring cylinders to main and cam centreline, line boring, bore centre corrections to blueprint specifications and lifter bore corrections.

See Engine Blueprinting for more information.


 The CWT Line Honing Machine was a recent import from the USA.  Line Honing is the process of finishing an engine's main bearing tunnel so the main bearings can be positioned correctly and the crank centre-line is perfectly true.  A small amount of material is removed from each mains cap and the block at the same time, so that the tunnel is perfectly cylindrical and uniform.  Line Honing creates a perfect finish to promote good heat transfer and precise bearing location.


Pictured here is our Sunnen CV-616 Automatic Cylinder Hone.

The ideal finish of an engine is made up of a pattern of scratches along the surface of the bore.  Under magnification, these scratches make up a series of peaks and valleys.  The piston rings run up and down along the peaks and the valleys act as oil reservoirs for lubrication to the cylinder.  The ideal plateau finish produced by this machine cannot be replicated using honing stones with hand held power tools.

For more on the perfect bore finish and plateau honing, see our techincal bulletin on Plateau Honing or the magazine article featured in Perth Street Car Magazine, Finishing Touch.


 It's a boring job!

While our Rottler F67A CNC Machining Centre is our most up-to-date machine for bore corrections, our original boring machine handles many of the older style engines.



Crankshaft Grinding up to 1.5m in length is available.


Our CWT computerised balancing machine was the first imported into Australia, and is regarded around the world as the best available.  Every balance comes with a print out analysing before and after balance in 1000 rpm increments. For more information on balancing, click here for the article "Spin Doctors", featured in Perth Street Car Magazine.


Magnetic crack testing is a specialized procedure where the component is magnetized using an electromagnetic field.  A mixture of magnetic particle fluid is sprayed over the component.  The particles in the fluid will congregate along any cracks, which can be seen with a black ultra-violet light.

See our technical bulletin on Crack Testing for more information.



 We rebuild your engine to your requirements.


The small end of the conrod, where the piston pin fits through, can house a small bush.  This bush can wear, resulting in a small knocking noise.  A new small end bush and honing to size is the correct repair.


 Galloways are able to offer a flywheel machining service.  Flywheel machining is essential when fitting a new clutch to prevent clutch shudder.  Keep in mind also, if you are fitting a new clutch kit, many manufacturers will not provide a warranty for their product if the flywheel is not machined.


At Galloway Engines, we fit pistons to conrods using a specialised machine.  The small end of the conrod is heated by a coiled heating element which is thermostat controlled, to prevent overheating.  When the correct temperature is reached, the conrod is immediately fitted to the piston.  Having your pistons professionally fitted to your conrods prevents any future problems caused by loose piston pins.

For more information on correctly fitting pistons to conrods, see our technical bulletin - Fitting Pistons to Conrods


Facing manifolds ensures that the correct seal between the engine and the manifold can be achieved.  A gasket will only be able to seal minor imperfections.  In short, a poor finish will result in a poor seal.

Frequently Asked Questions

How do I know if my engine needs reconditioning?

Tell-tale signs that your engine requires attention are that it has lost performance or efficiency, it blows excessive smoke or it has developed an unusual noise.  However, a vehicle needn't have these symptoms to benefit from a reconditoned engine.  A complete and comprehensive recondition of your engine will increase power, fuel efficiency and extend the life of your vehicle.

Galloway Engines is a precision workshop which deals in machining and reconditioning engines.  This ensures we are specialists in our field and only a quality job of the highest standard will be delivered.  We can arrange engine removal and fitment or contact your regular vehicle servicing centre for this service.

Can I supply my own parts?

Yes. You are quite welcome to supply your own new parts should you have a preference for a particular brand name.  However, our parts prices are very competitive and our high standards ensure that only quality parts are fitted to any job.  We have liaisons with many Australian and international companies allowing us to have access to world-wide sourcing of parts.
