Mercedes Benz E420 How-To: Understanding Oil Dipstick Problems
The oil dipstick is elemental in prolonging the life of the car's engine. It checks the oil level in the Mercedes Benz E420 engine, so you won't run the risk of overheating on the road by producing immense friction underneath the hood. Running your car below the minimum required quantity of oil won't even get you three miles away from Point A. Below are some tips to help you understand oil dipstick problems and how you can avoid them:
Does the lower part of the dipstick wriggle around the base attachment?
You should replace the oil dipstick when you start to feel some fidgeting behavior coming from the base, up to the lower end of the stick. This is completely normal if the stick happens to have been through a fairly long period of time; just imagine the amount of vibration it sustains while it is capped to the oil reservoir. However, if the dipstick is fairly new and it is already behaving that way; then, you should return it from the supplier and demand a replacement, free of charge. The new dipstick should not be acting that way, since it is made from very durable materials.
Does the dipstick show signs of rust?
An oil dipstick is made of a chrome tubing that is designed to withstand rust. While it is not usual for a dipstick to corrode, we still can't scratch off the fact that it is in constant contact with engine oil. The threat heightens every time you detach the dipstick from its location; through careless handling, the dipstick may come in contact with other liquids aside from oil-water being the most common, yet damaging of them all. Not only will this open up windows of opportunity for corrosive elements to eat up on the dipstick, it could also be potentially harmful for the engine. You might thoughtlessly mix water in the oil reservoir through the dipstick. Remember, engine oil should always be kept as pure as possible at all times.
