Head Gasket Repairs – Waterlooville

A blown head gasket is one of the more serious engine faults a vehicle can develop, but it’s not always the end of the road for the car. With an accurate diagnosis and the right repair carried out properly, many vehicles go on to give years of reliable service afterwards.

At Collison Motoring Services, we carry out head gasket diagnosis and repair on all makes and models. We use professional diagnostic equipment to confirm the fault before any work begins, because not every symptom that suggests a head gasket failure is actually one.

Signs of a head gasket problem:

  • White smoke from the exhaust, particularly on start-up
  • Coolant loss with no visible leak
  • Overheating or the temperature gauge rising unusually
  • Milky or mayonnaise-like oil on the dipstick or filler cap
  • Bubbling in the coolant reservoir

What does a head gasket repair involve?

The cylinder head is removed, the gasket replaced, and the head is inspected and skimmed if necessary to ensure a flat, clean mating surface. The extent of the work depends on whether any warping or additional damage has occurred. We’ll give you a full assessment and a clear quote once we’ve investigated, so you can make an informed decision about whether repair is the right route for your vehicle.

We carry out head gasket repairs for drivers from Waterlooville, Fareham, Gosport, and across the surrounding area. All work is guaranteed for 12 months on parts and labour.

As a Bosch Service network member, a HEVRA-approved EV and hybrid specialist, and an IMI-affiliated garage, we’re independently verified to meet recognised standards across the board. For you, that means confidence in the quality of the work, without having to just take our word for it.
