When you have a car, it’s helpful to know when parts need to be rebuilt or replaced. The engine is no exception — if you can spot some tell-tale signs it needs rebuilding, you can get to a reliable mechanic before problems worsen. Here are a few:
1. Excessive smoke – Large amounts of smoke coming from the tailpipe is always a sign there is an issue with the engine. Smoke can have different colours, indicating different problems. White smoke can point to coolant leaks (i.e. your engine is more likely to overheat). Blue smoke is a sign your oil is leaking into the combustion chamber (leading to more wear and tear on the engine from lack of lubrication).
2. Increased oil consumption – Oil changes are a normal part of car maintenance. If you find yourself replacing or topping up the oil too regularly (and there are no visible leaks), there may be a problem with valve guides. This signal can also indicate low oil pressure, which can only be confirmed by having a mechanic check (and possibly dismantle) the engine.
3. Loud knocking noises – If you hear this kind of noise coming from under the hood and it rises with your RPM, this can be a sign that the bearings are worn. The motor’s moving parts rest on these bearings, and improper lubrication and high mileage can cause an engine to suddenly stop working.
4. Rough idling – When operating normally, your engine should have a smooth and consistent RPM. If it feels rough and bumpy, this indicates that the engine could be having problems with parts like the fuel injector or spark plugs. Idling can be an indicator of an engine’s health, so have your car checked out if it seems abnormal.
5. Decreased engine performance – You can expect your engine to gradually lose some power after years of wear and tear. However, if your engine suddenly drops in power, bring it in for repairs. (Loss in engine performance can accompany other symptoms like idling and knocking sounds.)
6. Difficulty starting the engine – A lack of compression could be occurring in your engine (meaning that it has lost some efficiency). Other related signs are misfires and loss of performance.
7. Metal shavings in engine oil – This is usually a sign of severe wear on the bearings. Your engine needs a checkup to avoid potentially explosive accidents.
