What does it mean when your engine is making a knocking noise?

Knocking occurs when fuel burns unevenly in your engine’s cylinders. When cylinders have the correct balance of air and fuel, fuel will burn in small, regulated pockets instead of all at once. Engine knocking happens when fuel burns unevenly and those shocks go off at the wrong time.

Does engine knocking mean low oil?

Knocking sounds from your engine form one of the most common symptoms of lack of oil. At first, these sounds may stem from the under-lubricated camshafts and valve train. Piston wrist pins and rod bearings may also produce knocking sounds.

What causes oil to flow out of the dipstick?

Then there is the issue with excess oil pressure in the crankcase, causing the engine oil to flow out of the dipstick tube when there is no dipstick inside. The risk of contaminating the oil increases in such cases, and you are better off avoiding them in the first place.

What does a dipstick do in an engine?

A dipstick is something like a stick (not wooden, of course)that fits just right in the engine and is long enough to get close to the engine’s bottom. Since engine oil settles to the bottom of the engine, a functional dipstick lets your know the amount of oil you have in your engine. But what happens when there is no oil on dipstick?

How can you tell the oil level with a dipstick?

The dipstick will have two marks at the bottom. They are usually either lines or holes in the stick. The oil level can be read by looking to see where the oily part ends and the dry part begins. If it’s between the two marks, you’re good to go.

What should I do if I Can’t Find my dipstick?

You can always consult your owner’s manual if you can’t locate the correct dipstick. Before you pop the hood for a routine oil check, be sure you park your car on level ground. You don’t want all the oil sloshing to the back or to the front while you’re checking, which will give you an inaccurate reading. Also be sure to park someplace well lit.
