    Have you always wondered what a spark plug does? Our team here at Ponci's Diesel Center is here to help you out. It's simple in theory but does quite a lot of work for such a small piece of equipment. Your spark plug forces electricity to arc across a gap like a bolt of lightning at high voltage and fits into your engine's cylinder head, where it “sparks” to ignite the fuel and creates combustion within your engine. Without it, you wouldn't be able to drive your car or truck.

  • What Happens When You Don’t Change Your Oil?

    At Ponci's Diesel Center in Fortuna, CA, we recommend always making it a priority to change your oil on time. Here’s a look into why it’s so important, and what happens if you don’t keep up with oil changes.

    Sludge - If oil stays in an engine too long, sludge begins to build up anywhere oil can go. The oil absorbs tiny debris and contaminants, kind of like a liquid sponge - once it’s at capacity, that oil begins to stick, clog, and build up throughout the engine. Small veins that carry oil to components like actuators, turbos, and bearings will become blocked, starving critical components of oil and causing component or engine failure.

A simple but common issue on vehicles equipped with a manual transmission is shifter bushing issues. Your shifter has a bushing on the end of it, where it connects to the actual transmission. Its purpose is to provide tight, smooth shifting.
