oil filler caps
It may look like a simple design and an unimportant part, but the oil filler caps in our engines play an important role and here we will explain why.
Oil filler caps for our engines are crucial
The oil filler caps for our engines are a crucial part to ensure there's an airtight seal for the oil chamber. Essentially, it may be simple in design but this oil filler cap is important for this purpose and without one, or if your oil filler cap does not quite fit, then you risk engine oil leaking from the oil chamber. Also, debris and air can also enter the system and cause contamination. Usually, oil filler caps are a small plastic screw cap and you'll need to get one that fits your engine.
Should your oil filler cap break or you lose it, then do not be tempted to drive without the oil cap in place. The main reason is that you will lose enough oil from the chamber to create serious engine damage. For the relatively low price, the oil filler cap should be replaced to maintain the integrity of the oil system. Also, should you opt to drive without a cap in place you will be able to smell oil burning and see smoke from underneath the engine because this is being caused by the leaking oil hitting the hot exhaust manifold.
The oil filler cap
For those who may not be aware, the oil filler cap is located at the top of the engine and you should be wary about pouring too much oil in - pour it to the cap and you could cause a catastrophic issue for the engine when you come to start it up. It helps that on modern cars, vehicle manufacturers tend to use a different colour for the filler cap rather than have it in the normal black to help people recognise it more easily and for them to maintain oil levels properly. Most vehicle manufacturers will recommend that you check your engine oil level on a regular basis by using the dipstick, these are also a different colour in modern cars so they are recognised easily. You should only do so, however, when your vehicle is on flat ground to give an accurate reading on the dip stick. You should use kitchen towel or an old cloth to wipe the dirty oil from the dipstick, place it back into its position and check the oil level again. Should oil need topping up then you should add enough to the max level on the dipstick. As mentioned earlier, do not overfill oil past this level to avoid creating engine problems. Should yours need replacing or it has become broken for some reason, there's a wide range of oil filler caps available including OEM items and online suppliers.
