Oil sludge inside the filler cap

[Evholic_11]

Hello everyone! I got the oil light recently, so I had to top up the oil reservoir. While doing that, I noticed some light brown oil sludge inside the filler cap. I cleaned it, but after two weeks I noticed the same thing. I also noticed the water level being low. Should I be worried about something specific? Also, how to check the oil levels using the dip stick? Thanks!

While less likely, a faulty filler cap could be causing the problem by allowing moisture into the engine. However, this does not explain the coolant loss. Multiple issues could be causing the problem.

It's important to address this right away, as it could result in more serious damage, such as a warped cylinder head. Consider taking your vehicle to the mechanic for a thorough inspection. This could lead to overheating.

Before replacing the head gasket, they'll probably need to inspect the cylinder head for warping. If the head is damaged, you will require a replacement.

If you're comfortable working on your car, you might consider doing the repairs yourself. However, professional repair costs can be high.

To get a better idea of the extent of the coolant leak, change the oil and inspect it for signs of coolant contamination. This can help identify the underlying cause of the problem.

If you want to check the oil level using the dipstick, get a piece of toilet paper and lay it flat. Dip the stick into the oil, then press it on the paper. You will see where the oil is wet and where it is dry. It should be between the "low" and "high" marks.

If your car makes lots of short trips and doesn’t get very hot, sometimes gooey stuff (like mayo) can build up. Also, watch out for leaks! A common spot is a plastic pipe near the engine. It can crack as it gets older. Good luck!
