Troubleshooting problems in an engine of a classic car is more of an art than a skill. Most people, when they sense a problem, will simply replace parts in the engine until the problem has been resolved. This is not a particularly effective method and has the tendency to be very expensive. Luckily, there are easier methods to figure out what is wrong with a car’s engine.

Types of Classic Car Engine Problems

There are seven different categories into which an engine problem could fall. They have their own diagnostic leads, which will make figuring out what is wrong a much smoother process.

Rough Idle:

If a car is experiencing a rough idle, then there is the chance that a carburetor has come loose. There could also be a leak in the vacuum or breaker points that could have become worn down or wrongly adjusted so that they are no longer in the correct position. There is also a chance the polarity of the coil could be wrong.

Pinging:

You can usually detect pinging when your car is accelerating quickly or when towing a load. Pinging typically means that there is some combustion problem in the engine. This is usually a result of there being an excessive amount of lead in the ignition or the combustion chambers being inundated with carbon.

Hesitation:

If a classic car is experiencing hesitation, then it is usually a result of the pump stroke of the accelerator being weak, the vacuum advance not working at all, or the screws from the idle mix being set incorrectly.

Stalling:

This could be a simple result of the idle speed being lower than optimal. It could also be a result of there being a large leak in the vacuum, a problem which needs to be addressed immediately. If neither of these two issues are the problem, then you may want to check your ignition points, and see if your engine valves are leaking.

Oil Smoke on Startup:

If there is oil smoke being produced when the engine is being started, then that usually means that the valve guides or seals have been worn down to the point where they no longer function. You may even have a problem with a blown head gasket, which allows oil to leak into the compression cylinder.

High Amount of Oil Consumption:

If the car seems to be using more oil than it used to, your car may not have oil of the correct viscosity or that the oil has been diluted with gasoline. There is also a chance that the ring on the piston has been worn and needs to be replaced.

If you need extra assistance with identifying and repairing classic engine problems, consider the help of professional engine repair services like Speedy Brake and Apollo Muffler or a shop near you. However, by using this rough diagnostic guide, it is possible to locate the source of the engine problem in a short period of time. This saves the vehicle’s functionality, as well as a large amount of money for the owner of the car.
