Did you know that replacing a catalytic converter in a vehicle can cost between $945 to $2,475? If you are driving around with a burnt exhaust valve you will end up messing up your catalytic converter and having to spend more money repairing your car.
Keep reading for the top signs you want to look out for, to confirm whether or not you have a burnt exhaust valve.
1. Cold Engine
If you perform a cold engine test it will give you a good idea of whether the valve seal is faulty or not. After your car has been left outdoors overnight check the top of the cylinder’s head inside the valve cover. If you notice residual oil on the cover then it is a sign that you have a worn valve stem seal.
You can also check when the engine is on if the residual oil goes down through the bad seal into the combustion area because it will give out a blueish smoke from the tailpipe. You definitely want to know the differences because these bad exhaust valve symptoms show that you have to replace your valve before it leads to more serious problems.
Another sign that your exhaust valve is bad is if your car starts to idle at stop lights or at stop signs for an extended period of time. Whenever this happens there are high amounts of vacuum in the intake manifold because the throttle valve stays closed.
When you hit the gas, the seal that is eroding lets the oil slip past and then it goes through the valve guide that could burn the exhaust. If you see a blue-white smoke coming out of the tailpipe after you press the gas after a stop it is a big sign that you are dealing with a burnt exhaust.
If there is a lot of exhaust smoke when you press the gas, this is something to be concerned about. Especially if the smoke is a blue-white color and lasts for much longer after you start your vehicle.
Bad valves tend to show they are bad when there is excessive oil burning and the faulty piston rings and valve guides create an excessive production of smoke.
4. Engine Power Loss
When you attempt to engage the gas pedal and there is a lack of acceleration power it can be from having faulty valve seals and faulty piston rings. To be certain if the problem is due to the valve seal or the piston ring you can do a compression test.

Now that you have the top symptoms of a burnt exhaust valve, you can make an informed decision whether your car is in need of a new valve or not. If you feel that this is the case for you then you want to fix your car before the problem gets worst and costs you more money.
