Besides making it difficult to remove when replacing the oil filter, over-tightening can crush the filter gasket, causing it to leak. When not properly tightened, any vehicle part designed to seal against a leak will loosen from normal engine or driving vibrations and cause leaks.
The oil filter cleans the oil from contaminants and then releases it into the engine so it can circulate through the moving parts to lubricate them and collect heat. If the oil filter isn`t releasing the motor oil into the engine, the parts will suffer and your engine will sputter.
An oil filter obstruction or blockage can also cause oil pressure to suffer. Oil filters include pressure relief valves. If this valve is damaged, oil will easily pass right through, reducing pressure. It may go without saying, but it is important to also change the oil filter with each oil change.
This is the number one area where oil leaks can develop and, we won`t lie, it`s devastating. There is a long seal between your cylinder heads, oil pan, and the engine block, and if this seal breaks, oil can leak into the cylinders and damage your engine.

As far as the check engine light, that is not related to the oil leak(s). If you request a check engine light diagnostic, a certified mechanic from YourMechanic would use a code scanner to retrieve the specific diagnostic trouble code(s) from your car’s PCM that have caused the check engine light to illuminate. Using those codes, the appropriate individual vehicle components or sub-systems (often a sensor, circuit, and the like) are then carefully tested, based on specifications set forth in your car’s Factory Service Manual, to pinpoint the cause of the fault or the reason why the check engine light has illuminated. Once the faulty part or component is identified, it is explained to your satisfaction and the mechanic will let you know of the cost to repair. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
It is unlikely that an oil leak may have damaged the water pump, although not impossible if somehow the oil may have gotten inside the water pump. Again, this is not likely to happen. Water pumps often times will begin to produce a bit of a whining sound when they are starting to fail. A common problem also associated with this is the water pump may begin to leak around the water pump shaft due to the seal being damaged. Gaskets can also fail over time due to excessive heat and will eventually shrink causing them to fail and create an oil leak. I would recommend having an expert from YourMechanic come to your location to diagnose and repair your oil leak.
You can only add the manufacturer specified amount of oil to an engine. If you add too much oil, or too little oil, that will cause engine damage. You should check the engine oil dipstick to determine if there is presently too much oil in the engine. If there is too much, the excess will have to be removed to prevent engine damage.
The leak that you are referring to can be repaired if you request an oil leak diagnostic. If you have further questions or concerns as you decide what to do, do not hesitate to re-contact YourMechanic because we want you to make the most of your repair dollars and help you get the best possible results.
As far as how long an oil cooler will last, that’s hard to answer due to the fact that it’s a mechanical part that can fail for many reasons that simply can’t be predicted. However, if it were to happen again, one of our local ASE certified mechanics can complete the oil cooler replacement for you.
It sounds like you may need to replace the oil cap o-ring. If you haven’t done this before there are two O-rings to replace; a small green one on the base of the filter cap stem and the large black one that seals the filter cap (which seems to be the one you are having issues with). The large O-ring sits in a small square-shaped groove that is at the base of the oil filter cap. It is very easy to not properly seat the large O-ring because the threads for the oil cap are quite large and will accept the O-ring if you are not careful. I would suggest having a professional from YourMechanic come to your location to take a look at your vehicle.
