What is Cylinder Head Pressure Testing?

Cylinder heads can become cracked or distorted in various ways, for example when an engine overheats, or the cooling system fails. When this happens, or when we remove a cylinder head, we carry out pressure testing to identify any internal or external leaks or cracks.

SRS Engineering often carries out cylinder head pressure testing for customers in the Sutton, Croydon and Kingston areas and some signs that suggest a pressure test is necessary include:

  • Overheating
  • Unexplained Coolant Loss
  • External Coolant Leaks
  • Discolouration of Oil
  • Drop in Engine Performance
  • White Smoke Coming from the Exhaust

The Process

To check for faults, we seal the water outlets on the cylinder head before pressurising it with compressed air. If the pressure drops, we know there is a leak and use soapy water to find exactly where it is.

In addition, we heat up cylinder heads as we test them because some cracks will only become apparent while the engine is running. Consequently, it is important to carry out cylinder head pressure testing at temperature to ensure we do not miss any faults.

Because cylinder heads can crack inside as well as out, it is important to carry out a pressure test so we can identify any internal faults and not just visible cracks. This lets us know if cylinder heads are suitable for re-fitting, or if a replacement is necessary. Where possible, we carry out repairs and resurfacing before reassembling.

As with all our services, from cylinder reboring to engine reconditioning, safety is a main concern and we ensure all our customers in Sutton, Croydon and Kingston receive suitable services and leave our garage with a safe engine.
