What should always be replaced when rebuilding an engine?
If the purpose of the rebuild is to bring the engine back (or as close as feasibly possible) to its original performance, what are some things that should always be replaced? This obviously depends on the condition of the engine, so let’s say a 300,000 km engine which has had regular oil changes its whole life.
Why does my car make a rattling noise when I idle?
Under normal conditions, the engine should have a consistent, smooth sound indicating everything is running as it should. However, when the timing chain is loose, it may cause a vibration inside the motor and that will produce a rattling noise as the engine idles.
What causes a car engine not to work?
There are a number of possible causes, but you’re going to have to take a good look at your engine to try and diagnose the problem.
Are there things you can check if an engine is not high performance?
Things you can check and reuse if within spec and the engine is not a high performance engine.
What causes an engine to need a rebuild?
Some of the common problems have already been mentioned. Running issues like an engine misfire, bad oil leaks, engine burning oil, engine head gasket leaks, or your engine pistons slapping inside the cylinders are all reasons your car could need an engine rebuild.
What does the reduced engine power warning mean?
Asking what engaged reduced engine power warning message is somewhat like asking what turned on your check engine light —there are too many possibilities to list. Plus, GM has changed its fail-safe strategies over the years, so exactly what can engage the message depends on the year and model of your vehicle.
Can a failed knock sensor cause an engine rebuild?
A failed knock sensor can make it seem like your engine’s about to blow up. Low oil level will cause engine knock too. And other timing-related sensors can cause your car not to start. Even electrical problems could mean you need a replacement engine wiring harness, not a whole engine rebuild. Think you might need an engine restore or rebuild?
What to do when your engine power is reduced?
Technically, you can (usually) drive slowly when Engine Power Reduced is illuminated on the dash. However, doing so is not recommended. It is best to tow your vehicle to the nearest repair facility, as driving at extremely low speeds can be dangerous.
