How Do We Find An Oil Leak?


First, we check your car while it's parked. Fresh oil spots on the driveway usually point us in the right direction.


Visual Inspection Steps:

  • Pop the hood and scan for wet, shiny, or oily patches.
  • Peek at the oil pan underneath your car.
  • Look closely at gaskets and seals around the engine.
  • Check hoses and all those connections.


We always grab a flashlight to light up those dark corners. Black or brown stains on engine parts usually give away the leak's location.


Advanced Detection Methods:

  • UV dye test—we mix in a special dye with your oil.
  • Pressure testing helps us spot sneaky leaks.
  • Engine degreasing makes new oil marks stand out.


That UV dye trick is great for tiny leaks. We add the dye, ask you to drive a bit, then use a UV light to catch the glowing trail.


Before any test, we clean the engine. Old oil stains just get in the way and make things confusing.


Common Leak Locations

  • Oil drain plug
  • Oil filter area
  • Valve cover gaskets
  • Oil pan gasket
  • Front and rear main seals


Gaskets and seals are usually the troublemakers. They wear out, especially the rubber ones, and oil sneaks past.


We like to snap photos of the leak spots. That way, you see exactly what's up and what needs fixing.

Why Does Your Vehicle Leak Oil?


Oil leaks happen for a bunch of reasons.


  • Worn gaskets: heat and age make them crack and shrink.
  • Loose drain plugs: this can be from overtightening the plug during an oil change and damages the threads. Then oil seeps out slowly.
  • Oil filter: a loose filter or busted O-ring lets oil drip out. We always check this first.
  • High mileage: rough on seals. Cars over 100,000 miles usually have a few leaks just from wear and tear.
  • Bad maintenance: skipping oil changes creates sludge.


Common leak spots:

  • Oil pan gasket
  • Valve cover gasket
  • Rear main seal
  • Oil cooler lines
  • Timing cover seal


Ventura’s wild temperature swings don’t help. Cold makes rubber brittle, hot days make seals swell and shrink.


Most leaks start tiny. A few drops can turn into a real headache if you ignore them.

Signs Of An Oil Leak


There are many signs of an oil leak with your vehicle, you just have to know what to look for. Fresh leaks look black or dark brown while older ones fade out and get lighter over time. 


  • Dark spots under your parked car
  • Low oil on your dipstick
  • Burning oil smell when you’re driving
  • Louder than normal sounding engine
  • Blue exhaust smoke



We spot oil stains on engine parts during inspections. Look for greasy or wet spots around these areas:

  • Oil pan gasket
  • Valve covers
  • Oil filter
  • Drain plug


Some leaks are sneaky and hard to spot. We use special tools to track down those hidden ones before they do real damage.


If you see any of these signs, don’t wait. Bring your car in for an inspection.

Reviews Stars Rating | DMC Automotive Repair

"DDMC installed the 2004R trans in my 67 Nova over 10 years ago and it has been flawless. So when I had an oil leak that looked to be the rear main seal, I took it to DMC. They found the leak at the oil pressure fitting at fixed it at 20% cost of what I expected. 😀"
