7 Signs Your Mack or Volvo May Need An Engine Overhaul


Engine not behaving as well as it used to? You might need an Engine Overhaul. It’s the best way to get like-new engine performance without paying for a new engine. Overhauls are offered at 4 levels of service and are typically performed every 7 to 10 years or every 800,000 to 1 million miles. By watching out for the following problems, you can determine whether or not an engine overhaul may be the right thing for you.

Blue or Black Exhaust
If your truck is emitting blue or black exhaust, this is a sign that your cylinders are burning oil or fuel. This is caused by worn or damaged piston rings, injectors, cylinder liners, or head gaskets.

White Exhaust
If your Volvo is emitting white exhaust, it is likely caused by worn or damaged liner seals, main bearings, piston skirts or valves.

Increased Oil Consumption
If that oil light seems to be coming on and that measuring stick is as dry as a bone, your engine might have a problem burning or leaking oil; neither situations are good. This is likely caused by damage to piston rings, cylinder liner, or valve and stem guides.

Engine Knocking
Knocking engine? Combustion timing might be off in one or more cylinders or oil contamination may have occurred. This is caused by damage in the liner seals, main bearings, piston skirts, or valves.
