We undertake in skimming both aluminium and cast cylinder heads to a high standard. It is advisable to have your head skimmed after head gasket failure or if it has been removed to repair cam belt failure.

Valve Seat Cutting

We cut valve seats as sometimes they can distort due to an overheating engine. A high milage engine has valve seat wear, re-cutting the valve seats ensures an excellent seal between the valve and seat. 

Cylinder Block Resurfacing

Cylinder block resurfacing or decking is carried out on a wet skimmer, it is to ensure that it is a perfectly flat surface, for a perfect gasket seal. Decking is can be carried out after overheating.

Cylinder Block Boring

It is necessary to rebore the cylinder block when the cylinders have either, become damaged or excessively worn. In the case of a competition engine we rebore to increase capacity.

Cylinder Block Honing

Cross hatch honing of bores when new piston rings are to be fitted.

Porting & Polishing

The cleaning and re-shaping of the inlet and exhaust ports within the cylinder head to maximise gas flow, both in and out of the engine. 

Flywheel Lightening & Balancing

Competition use: removing weight from the flywheel to make an engine rev easier.

Crankshaft Balancing

Competition use: crankshafts are balanced for a cleaner, smoother rev range.

Injector Removal

A common problem is seized injectors. These need to be extracted correctly without damaging the cylinder head. We can remove seized injectors with the cylinder head fitted or removed from the vehicle with the latest hydraulic equipment.
