If you are noticing traces of oil in the oil cooler area (inner V) of your engine, it could be an indication of a few different issues. Here are some steps you can take to diagnose and fix the issue:
Inspect the oil cooler: Check the oil cooler for any signs of damage or leaks. If the oil cooler is damaged or has a leak, it can cause oil to accumulate in the area.
Check the oil filter and gasket: Inspect the oil filter and gasket for any signs of damage or wear. If the gasket is worn or damaged, it can cause oil to leak and accumulate in the area.
Inspect the valve cover gasket: Check the valve cover gasket for any signs of damage or wear. A damaged gasket can cause oil to leak and accumulate in the area.
Inspect the head gasket: A damaged or worn head gasket can cause oil to leak into the coolant system, which can cause oil to accumulate in the oil cooler area.
Check the PCV valve: The Positive Crankcase Ventilation (PCV) valve helps to regulate the pressure inside the engine. If the PCV valve is clogged or malfunctioning, it can cause oil to accumulate in the oil cooler area.
Inspect the engine for other leaks: Check the engine for any other leaks that could be causing oil to accumulate in the oil cooler area.
Based on the findings from the above steps, repair or replace any faulty components that are causing the issue. If you are not able to diagnose or fix the issue on your own, it is recommended to take your vehicle to a certified mechanic or dealership for further diagnosis and repair. A professional may be able to perform a more thorough inspection of the engine and identify any other issues that could be causing the problem.
