When you are working with diesel engines, you need to make sure that you maintain them regularly because even a small issue can lead to bigger problems if left unattended. However, engine overhauls are a great way of solving any issues that arise, and they do not cost as much as a replacement. During the overhaul process, what happens is that the engine is taken apart and any faulty components of it are identified, replaced, and cleaned. After the faulty components are identified and replaced, you can get a professional to help in rebuilding the engine.
A diesel machine’s power and performance improve significantly after an overhaul. If you follow up with regular maintenance, you can increase the life expectancy of your engine as well. The following are a few signs that will help you identify whether your engine needs an overhaul.
Accumulation of Oil Sludge
One thing that gives away engine problems is if there is oil sludge accumulated on the dipstick or fill cap. Usually, the buildup is of wasted oil, grime, and coolants. If you find oil sludge, it is an indicator that the engine is not lubricated properly. If you find a thick mixture building up around your engine, you may be in need of an overhaul. Ignoring the presence of oil sludge around your engine is not a good idea as it can impact the performance of your engine and cause other issues like excessive fuel consumption or power loss.
Metal Shavings
Look for any metal shavings in the engine’s oil. If you spot some, they are probably caused by friction between components. This happens because of improper lubrication. Make sure to act quickly if you spot metal shavings in your engine’s oil. If the oil carries the shavings throughout the engine, it can cause further damage and can also cause problems with other components, and that damage would end up costing you a lot more than an overhaul.
Increase in Oil and Coolant Consumption
If you notice a drastic increase in your diesel engine’s oil and coolant consumption, it could be due to a number of issues. This could have happened because the piston rings are worn out. If they are not properly placed, they cannot ensure that the diesel fuel will not get in the crankcase. It is important to remember that diesel is not a lubricant like oil, and its leakage can result in serious damage. A few other things like an oil leak or a cracked cylinder head may also be responsible for the increase in oil and coolant consumption.
Excessive Smoke
Excessive smoke is a clear indicator of your engine needing an overhaul. A lot of operators fail to see the exhaust coming from the engine while in operation, and therefore, the problem often remains undetected for a time. You can determine what the issue is by observing the smoke itself, and if it is blue, your engine is burning oil. This could also mean that the diesel may be flowing incorrectly. However, if the smoke is white, it could be because of coolant leaking into the engine.
If your diesel engine is showing any of these signs, it may be time for an overhaul. If you ignore these issues, you will end up regretting it when you have to contact your industrial equipment supplier for a replacement. An overhaul would only cost you a fraction of what you would have to pay if you opt for replacement.
