Engine Repair

Hear a strange noise coming from under the hood and suspect engine trouble? Whether knocking, rattling, sputtering, hissing, grinding, or clunking, come over to our shop for engine diagnostics. The engine is one of the most complex components of a vehicle. With a variety of moving parts and necessary regular maintenance to keep functioning, engine repair is a common reason people come to us. Our experience of over 30 years helps us diagnose your vehicle’s problem and get you back on the road!

The engine has so many components, if one gets out of place, it can throw off the whole system. The following are some of the parts we often repair or replace:

  • Spark Plugs
  • Fuel Injectors
  • Heads
  • Head Gasket
  • Camshaft
  • Crankshaft
  • Fan or Serpentine Belt
  • Rod Bearings
  • Oil Pump
  • Pushrods
  • Timing Belt

Because there are so many integral parts to an engine, and many of their functions depend on one another, it’s crucial that your engine repair be put in the right hands. At Big Jim’s, we don’t mess around with your engine, we intend to leave it better than we found it! And if your engine is shot, we also do engine replacement!

Spark Plugs
Who knew such a tiny part could cause such trouble? We did. Spark plugs are what give your engine the ability to burn fuel and use it to power your vehicle. You can imagine that if these aren’t working properly, the car won’t either. Spark plugs are also the type of item that wear out over time. Often this will result in a knocking noise, a misfire such as sputtering, slow acceleration, poor fuel economy, and sometimes trouble starting the vehicle. If caught quickly you can prevent further serious damage to your engine. A new set of properly gapped spark plugs will help with fuel economy and acceleration. Your owner’s manual should indicate when your spark plugs are recommended to be replaced. It’s typically every 40,000 to 60,000 miles. This is also a great time to check your vehicle’s fuel filter if it has one.

Timing Is Everything
Your engine’s timing belt can affect several parts in your vehicle and its ability to function. This rubber belt, or sometimes a metal chain, ensures the properly timed opening and closing of the intake and exhaust valves in your engine. This in turn affects the entire combustion process which gives your engine power. It’s also usually tied to the water pump and power steering in most vehicles, which can result in other issues as well. Check your owner's manual to see when the manufacturer recommends replacement. If you are past the recommended mileage to replace your timing belt you are putting your engine at serious risk. In most cars, if the timing belt malfunctions it ruins the majority of the moving parts inside the motor. So be sure to replace it before you have the problem. Otherwise you may be buying a new car!

Don't Blow a Gasket
The engine contains many different gaskets that keep things running smoothly, and a bad or failing gasket is not something you want to ignore! If your head gasket is blown, you might notice an engine misfire due to loss of compression. This can then result in rough idling, engine overheating, and coolant leaking into the oil compartment or onto a spark plug. Overheating is a common symptom of a blown head gasket, and if it goes unnoticed or worse, ignored, it can cause damage to other parts of your vehicle such as the radiator, cooling system, and hoses. We have the knowledge and experience you can trust to diagnose your vehicle’s problems and get you back in tip top shape!

Oil Pressure
You may notice the engine’s temperature gauge on your dash is showing an increase, and you might even have trouble starting your car, both of which can signify low oil pressure. Keeping the numerous metal parts of an engine moving smoothly and without friction is vital to your engine’s health and functionality. If your oil pump is not distributing oil to the engine’s various parts or if you have a leak, you’re likely to run into problems. We can take care of you at Big Jim’s!
