The most important thing about reconditioning your cylinder head is that you know that it will be done

Giving you the confidence and ensuring the reconditioning, overhauling and Servicing of your cylinder head is done right.

On arrival your cylinder head or heads will be given a job number then tagged and issued with a job card.

  • All cylinder heads are dismantled and placed in a hot acid bath to remove all carbon build up , then placed into our hot parts washer to remove any leftover residue and then buffed to achieve the best result.
  • All our cylinder heads are pressure tested with our Donnelly pressure tester, this is designed to operate hot water (approx. 70deg) through a pressurized vessel. To simulate operating conditions and detect any leakage through expansion & pressure.
  • All cylinder heads are placed in the lectro magnaflux crack tester.

(Aluminum cylinder heads cannot be crack tested)

In typical operation to crack test a cylinder head we place the head into the machine and it is given a shot of magnetizing current. Then the crack testing fluid is applied (this contains fluorescent particles) an ultraviolet lamp is used to examine for longitudinal or latitude cracks. Of course demagnetizing is a critical part of the operation.

  • Our quote process requires 39 individual check points, from bolt holes, to injector tubes, valves, manifold studs, cylinder head thickness & hardness and many more. All the results are then recorded on the job card and then the job is quoted.
