In this video how show how to replace and why you should replace your oil cap on any car. Investing in a replacement oil cap is a simple choice. Either you can risk blowing your engine, replace your entire car due to a fire, or risk allowing debris to penetrate the oil and potentially destroy several essential components. Here are just a few reasons to immediately replace missing oil cap.
A Bad Oil Cap Can Cause Vacuum Leak
Missing oil caps can cause your PCV system to pull in air from the breather cap and into your engine’s intake system, ultimately resulting in a vacuum leak. These leaks can be engine killers, as they increase engine temperatures dramatically. The cost of replacing or repairing your engine versus spending a few dollars on fuel cap is reason enough to replace the oil cap right away. Ideally, you’ll have a second vehicle to rely on until you receive your replacement oil cap, but if you plan to head to the parts store instead, be sure to keep your RPM’s and throttle as low as possible which will lead to the next reason Oil Loss.
A Bad Oil Cap A Cause Oil Loss
Pressure from the engine can put stress on the oil filler cap, causing oil to leak out, if the oil cap (plastic ones in particular) overtime will brake, loosen, or you just missing the oil cap. The most common site of leaking oil in automobiles is the valve cover gasket. The valve cover gasket prevents the oil from leaking all over the engine and onto the ground.
A Bad Or Loose Oil Cap
If there is not sufficient oil the activity of the engine can cause overheating, and also cause the parts of an engine to wear down due to constant friction. If the car is suffering from low energy oil pressure, it means that there is insufficient oil lubrication being supplied.
Air Coming Out The Oil Cap Can Cause Bad fuel economy, etc...
Most motors will blow air from the oil filler cap due to the pressure generated in the crankcase from all of the moving components. Engine blow by is when the engine's piston rings have worn out enough to allow combustion gases and pressure to escape past the rings, into the engine crankcase The result of having a loose oil cap is that some of the air entering the engine drawn in by the PCV (Positive Crankcase Ventilation) will not go through the MAF sensor as it normally should. Instead being drawn in via the loose oil cap, and thus not be accounted for in fuel mixture control that uses the MAF (Mass Air Flow) sensor to determine the volume of air flowing into the engine. This is similar to a leaking air intake snorkel or defective MAF (Mass Air Flow) that will cause incorrect mixture calculations which in result cause bad fuel economy. In addition to this as the air drawn into the crankcase via the leaking oil cap is not filtered as it is if drawn in via the intake snorkel that non filtered dirty air will contaminate the engine oil and cause it to be prematurely compromised in it ability to lubricate the engine. This condition is worsened by air back flowing in to the snorkel from the crankcase that contains oil vapor that should be going into the PCV (Positive Crankcase Ventilation) valve and not the air intake, the result is the oil vapor will contaminate the throttle plate causing a build of dirt on it and that may cause poor idle control in addition to the poor mileage from the first condition. Next loose oil cap can let in unwanted stuff enter your engine which leads to next topic
Loose Oil Cap can also let in dirt or any other kind of debris such as water vapor, Delaying getting a replacement oil cap can let a slew of “junk” and water vapor into your oil reserves. Because clean oil is essential to keeping your vehicle’s engine operational, keeping debris out is definitely wise. These violators can destroy the engine by depositing harsh materials on internal bearing surfaces. A missing oil cap will allow the engine’s evaporative system to suck unfiltered air directly into the engine crankcase – a surefire costly mistake.
