Potential Solutions and Repairs
Addressing oil leaks promptly is vital for your car's health. Here are common solutions:
buildGasket & Seal Replacement
Many leaks stem from worn-out gaskets (e.g., oil pan, valve cover, VTEC spool valve) or seals (crankshaft, camshaft). Replacing these with new, high-quality parts is a common and effective repair. Ensure mating surfaces are clean before installation.
tuneOil Filter & Drain Plug Check
Sometimes, leaks are as simple as a loose oil filter or drain plug, or a damaged oil drain plug washer. Ensure these are tightened to manufacturer specifications and replace the washer during every oil change.
sensorsSensor Replacement
Leaking oil pressure sensors are a relatively easy and affordable fix. These plastic components can crack over time and are often accessible for DIY replacement.

For persistent or hard-to-diagnose leaks, a professional mechanic can perform a UV dye test. A special dye is added to the oil, and a UV light reveals the exact source of the leak, even in hard-to-reach areas.
