The piston rings in your vehicle’s engine are accountable for managing oil pressure and controlling engine oil usage. Broken or worn engine piston rings will generally result in a multitude of issues, and will certainly need some engine repair work which could include a full engine rebuild. Below are a few of the indications that might suggest your car or motorbike has actually fried one of more of its piston rings.
Typical Signs of Worn Out Piston Rings
Issues with your engine’s piston rings typically show signs or indicators that resemble some of the other issues associated with low compression in a car engine. While the following signs are not solely created by defective piston rings, they are an excellent indication that you ought to at least inspect the rings for wear and to see if they have to be changed.
Below this video is a list of the most typical signs for bad piston rings:
- White or gray smoke coming for the exhaust
- Extreme oil usage
- Low power for acceleration when starting up or overtaking
- Loss of power overall.
If you think your engine may have badly worn piston rings, or if your car is showing any of the above signs, you will need to discuss the situation with Croft Autotech engineers. They will be able to have carry out a compression trial run on each engine cylinder. This simply involves removing each spark plug in turn to insert a compression tester and starting the engine.
Having tested each engine cylinder in turn our mechanic will be able to give you a report on the extent of wear on each piston. This series of compression tests along with a full engine diagnostics test will enable us to give recommendations about the next stage to rectify any problems found.
Will I need a full engine rebuild?
It is not possible to answer that question until we have done our compression tests and run our diagnostic software programmes. It may be necessary to consider the possibility of full engine rebuilds (or just the top half of the engine being rebuilt) but we obviously can not make that recommendation without more detail of the car’s condition.
If you really want to know about the potential cost and timescale involved you need to ring us on 01358 722112 and speak to Scott our engine rebuild specialist or bring it in for a full health check.
