In the diesel world, "blow-by" is a term you're bound to run across at some point if your line of work involves diesel-powered vehicles of any kind. What is blow-by, what causes it, and how concerned should you be? At South Mountain Collision & Auto Center in Middletown, MD, our fleet maintenance and diesel technicians see it on a regular basis. Here we'll take a quick look at blow-by, correcting it, and preventing it.
What is Blow-By? - Diesel blow-by is a term that describes an event of lost compression into the crankcase. Blow-by occurs whenever a burnt or unburnt fuel and air mixture escape from the cylinder and past the piston rings and into the crankcase. In a perfect world, the piston would be sealed tightly in the cylinder, able to move up and down but keeping all the air and fuel and exhaust that enters or exits the cylinder during the combustion process out of the crankcase. As you'll see, this perfect world doesn't exist, but it is important to minimize the amount of blow-by in a diesel engine.

Most commercial diesel engines these days are turbocharged. Turbos dramatically increase power and efficiency, particularly on diesel engines, which makes them a must-have item on engines that rely heavily on both. However, sometimes issues arise in turbo systems; at South Mountain Collision & Auto Center in Middletown, we can fix that.

The fuel system is an integral aspect of any combustion engine, but it’s particularly important on diesel trucks. Your Ford, Dodge, or Chevrolet pickup requires a perfectly functioning fuel system, devoid of buildup, leaks, and debris, to provide you with the most powerful and efficient engine performance possible. At South Mountain Collision & Auto Center in Middletown, we understand that fuel system flushing is an essential process in maintaining a properly functioning engine.

When you are having trouble with your car or truck starting and you open the hood up to take a peek to see this....you'll see what an overly corroded battery looks like. This happens naturally over time on vehicle battery terminals. If you are like 99% of normal Middletown drivers, you don't check your oil or your battery so you don't keep an eye on the amount of corrosion that's building up on your car or truck battery. Here at South Mountain Collision & Auto Center, we do and there are solvents that we can use here in the shop during a battery maintenance service that will help slow the corrosion process but nothing that can prevent it 100%. Way before it gets to this point, we will be suggesting you consider replacing the battery.
