ME170313 Engine Intake Exhaust Valve for MITSUBISHI 6D17

What are the Common bad Engine valve symptoms?

Properly sealed valves are essential for your car to operate at its best. Any issue with the car valve is necessary, especially if the engine is involved. Any seal or valve problem will necessitate an engine rebuild to get your car back in operating order and will cost you way more than the servicing cost.  Here are a few of the symptoms:

1. Popping/Ticking Noise
The first sign of faulty Engine Intake Exhaust Valve seals in your car is popping noises. The engine makes a louder roar as you go faster. It indicates that some of the valve’s train parts are misaligned or have worn out. Another possible cause is the car engine not receiving enough lubricant.

Most vehicles feature hydraulic lifters. These lifters need steady pressure and continuous lubrication. If there is damage, you can hear a popping/ticking noise.

2. Blue Exhaust Smoke
Blue smoke coming from the exhaust pipe is the most typical sign of a damaged valve seal. This may be brought on by an intake valve seal leak, which allows oil to enter the combustion chamber and burn there. The oil may evaporate because of a leaking exhaust valve seal, forcing oil into the exhaust pipe. The smoke gets thick as the issue gets worse. You’ll observe that the blue smoke is more persistent than previously and is visible at fast speeds.

3. Excessive Oil Consumption
One of the bad valve symptoms is Excessive Oil Consumption. Oil consumption will be extremely high due to faulty Engine Intake Exhaust Valve seals. Bad seals will result in an oil loss which you can witness on the oil dipstick. A noticeable oil reduction caused by the oil being burned alongside the fuel can be found by accurately recording the oil level on the dipstick.
A typical engine holds about 4 litres of engine oil, and if you continue to drive your car while the valve seals are leaking, you can see the oil level dropping. If there are no visible engine oil leaks to account for the loss, faulty valve seals are the reason.
4. Rough Idling
Bad Engine Intake Exhaust Valve seals typically appear when the car is idling at stop lights. The cause of this symptom is that prolonged idling of the vehicles causes significant levels of vacuum to build up at the intake manifold. This causes oil to be drawn into the heads and collected at the valve stems. When there is a poor valve seal, the oil will be drawn to the valve guide and pass through the rapidly disintegrating seal when accelerating. Checking your valve seals is necessary if you have rough idling and blue smoke.
