Your Valve Seals Are Failing

Your engine's cylinder mind is located straight above the combustion chamber. A number of valves are contained inside the cylinder head. Under normal conditions, every valve features a seal which prevents oil from dripping into the combustion chamber. If the seals deteriorate, they'll fail to hold out their job properly. As a result, oil enters the chamber and the 4-stroke combustion process burns it Exhaust Tail Pipe .

Your PCV Is Jammed Or Clogged

As your motor goes through its internal combustion process, pressure builds inside it. The PCV permits this pressure to dissipate. However, over time, it can come to be clogged with carbon, a side effect of the combustion process. When this happens, it can lead to excess pressurization of the crankcase. The result? Oil ends up getting directed into the motor exactly where it burns, producing smoke out of your tailpipe Auto Muffler.

Your Piston Rings Are Worn

Each of your pistons features a ring close to it that functions as a seal. One of their careers would be to prevent energy from escaping the combustion chamber throughout the 4-stroke process. They also lubricate the walls of the cylinder. Like most parts, the rings can deteriorate over time. once they do, the pressure created throughout combustion is directed towards crankcase. Remember what happened within the situation of the PCV clog causing excess pressurization in that part? a similar thing takes place - oil helps make its way into the engine.

What Does Blue Exhaust Mean?

The color of exhaust confuses a great deal of motorists. Sometimes, it's white while in other cases, it's dark gray or blue. First, if the exhaust is white (and assuming it is not caused by normal condensation), it might imply a leak in your car's mind gasket. If the gasket leaks, water can gain access towards combustion chamber. If the exhaust is dark gray, it may suggest that your master cylinder is failing.

Blue smoke implies that oil is getting burned inside the combustion chamber. And that is caused by broken valve seals, a jammed PCV, or deteriorating piston rings.

Here's the takeaway: when you notice smoke coming out of your vehicle's tailpipe, have a mechanic consider a look. Something has failed or deteriorated also it will not get better on its own. when you wait around to have it repaired, you risk exposing your car to even bigger troubles down the road.
