Oil Leak Repair Services

Ignore a leak for too long and you could be looking at engine failure.


We use advanced diagnostic gear to zero in on exactly where your oil leak starts. Here's how our oil leak repair process goes:


  1. Thorough Inspection – We check all the likely leak points.
  2. Precise Diagnosis – We nail down the exact source of the leak.
  3. Quality Repairs – We use OEM or solid replacement parts.
  4. Verification Testing – We make sure the repair actually worked.



We work on all makes and models, domestic or foreign. Our team can handle anything from a quick gasket swap to complicated jobs that mean pulling apart the engine.

Service Process

Our Oil Leak Diagnostic Process

We start with a visual inspection of your engine and undercarriage. Oil stains or wet spots can tell us plenty about where the leak’s hiding.

Then we use special dyes that mix with your engine oil. Under UV light, even tiny leaks glow so our techs can spot them.


After that, our team runs pressure tests on different engine parts. This helps us figure out if seals, gaskets, or other bits are failing and letting oil escape.


Common areas we check include:


  • Oil pan and drain plug
  • Valve cover gaskets
  • Timing cover seals
  • Rear main seals
  • Oil pressure sending units


We also check your oil levels and the oil’s condition. Low or dirty oil sometimes points to leak-related issues.


Once we find the problem, we explain it in detail and give you a straightforward estimate for repairs. You won’t get any nasty surprises.



Most diagnostics only take about 1–2 hours, depending on how complicated your vehicle is. We aim to get you back on the road as quickly as possible.

Warning Signs

Common Signs of an Oil Leak

Oil leaks can really mess up your vehicle if you let them go. Spotting the signs early can save you a fortune in repairs.


The most obvious sign? Oil spots under your car. These dark brown or black puddles usually show up after you’ve parked for a while.


If you smell burning oil while driving, that’s a big red flag. Oil dripping onto hot engine parts or the exhaust will do that.


Dashboard warning lights can clue you in, too. If your oil pressure light pops on or your oil level drops fast, you might have a leak.


We see these symptoms a lot:


  • Engine smoke or steam
  • Dirty, grimy engine parts
  • Poor engine performance
  • Overheating engine


Blue exhaust smoke is especially worrying—it means oil’s burning inside your engine. Don’t wait on that one.



Check your oil level every couple of weeks with the dipstick when your engine’s cool and on level ground. It’s a simple habit that can save you a headache.


If you notice any of these signs, bring your car in for an inspection. Catching leaks early keeps your car running smooth and your wallet a little happier.

Oil Leaks

Causes of Oil Leaks

  • Degraded gaskets and seals
  • Damaged oil pan
  • Loose oil filter or drain plug
  • Broken oil cooler lines
  • Worn valve cover gaskets
  • Timing cover leaks
  • Oil pressure sensor failures


If you skip regular oil changes, old oil turns sludgy and puts extra stress on seals and gaskets. That’s just asking for leaks.


Cars with a lot of miles usually see more leaks. As your car ages, those seals get hard and can’t keep oil in as well.



Wild temperature swings in Maryland Heights don’t help, either. Cold winters and hot summers make materials expand and contract, and that can open up new places for oil to escape.

Our Expertise

Why Oil Leaks Should Be Repaired Immediately

Oil leaks can cause serious damage to your car and the environment if you let them go. Fixing them right away saves you money and keeps bigger problems from popping up later.


Preventative Maintenance Tips

Regular vehicle inspections help you catch oil leaks before they get messy. Take a quick look under your car for oil spots regularly—it's easy to forget, but worth it.


Check your oil levels every now and then, not just during scheduled service. If your car suddenly craves more oil, that's a red flag for a possible leak.

After an oil change, double-check that the oil cap and drain plug are tight. It's surprisingly common to overlook these, and loose parts can cause leaks.


Pick high-quality oil and filters when it's time for a change. In our experience, better products seal things up tighter and can help prevent leaks altogether.



Swap out gaskets and seals as your car's manual suggests. These parts wear out over time and, let's face it, they're usually the ones to blame for leaks.
