Fuel pump replacement is a necessary part of your car's maintenance.  A fuel pump transfers fuel from your tank to your engine. It supplies the fuel at a constant pressure to ensure that the engine is running smoothly. Mechanical or electronic fuel pumps are standard in your vehicle. A mechanical pump has a diaphragm mounted on the outside of the fuel tank that expands and contracts, creating a vacuum system that expels fuel out of the gas tank and into the engine. Electronic pumps use an electromagnetic motor inside the fuel tank that forces fuel into the engine at a high pressure. Cars with carburetors contain mechanical pumps while vehicles with fuel injection systems have electric pumps. The motion of the engine directly drives a mechanical pump. Since mechanical pumps contain few moving parts, they tend to be reliable and easy to diagnose and fix. The most common problems with mechanical pumps occur when the diaphragm is damaged in some way, which throws the pressure sy ... read more

Walnut blasting is now being offered at DJ Foreign Auto Care! What is walnut blasting you may ask? Walnut blasting is a process that is used to treat heavy carbon build-up. Cars require oxygen to run. With modern direct injection engines, when your foot is placed on the accelerator, the car releases gasoline into the combustion chamber of the vehicle. The spark plugs then ignite the gasoline in the combustion chamber, causing the car to run. Carbon is released into the engine as a byproduct of this process.  The carbon interferes with the vehicle’s normal combustion, which in turn alters the compression ratio, operating temperature, and sensor readings.  The carbon builds up and coats the inside of your engine including the air intake valves, combustion chamber, and exhaust, restricting your car’s ability to breathe and also affecting your car’s efficiency and power. When the carbon builds up, one of the common ways to clean it out of your engine is through ... read more

Tweet"New" Engines: If you are replacing your engine, the process is not as simple as removing the old engine and dropping in a new one. Replacing your engine can be a long and difficult process; since as well as being big and heavy, engines are made up of a lot of little parts.  Also an engine connects and works with several other systems including the electrical system, exhaust, transmission and cooling system. Since most people are not going to pay extremely high prices for a brand new or re-manufactured-rebuilt engine, the general process for replacing your engine starts with your car repair shop finding a used engine that fits your car.  The "new" used engine should have a warranty on it, should be free from damage, should have good compression and relatively low mileage, if possible. Replacing Your Engine: Once the right engine is f ... read more

  BMW Crankcase Vent Valve Failure: BMW crankcase vent valves fail more often this time of year and we see more of these types of problems as the weather gets colder. The BMW crankcase ventilation valve is also known as the oil separator, CCV, or PCV valve.  According to Wikipedia, "A crankcase ventilation system is a one way passage for gases to escape in a controlled manner from the crankcase of an internal combustion engine.  This is necessary because internal combustion inevitably involves a small but continual amount of blow-by, which occurs when some of the gases from the combustion leak past the piston rings (t ... read more

Tweet Many European import car engines are damaged when North American engine oil is used instead of the European Engine Oil recommended by the manufacturers. European car makers insist on very specific types of motor oils to be used, motor oils that follow European specifications which are different from the specifications in North America. Specific European Engine Oil: From ultimatesyntheticoil.com: From techmax.ca: To find out more about what type of oil to use for your vehicle, take a look at your owner's manual, which will specify what kind of oil should be used or you can look at the manufacture's web site. At DJ Foreign Auto Care, we follow the manufacturers' specificatio ... read more
