Combustion leak detector FAQs:

Are you confused about which Combustion leak detector to buy? Do you have many questions that need answering before making your purchase? Don’t worry! Our Frequently Asked Questions list will help you find the perfect Combustion leak detector for all your needs. Now, you can shop confidently, knowing we’ve researched for you!

1. How does an engine combustion leak detector work?

An engine combustion leak detector uses a special Reaction Liquid to detect hydrocarbons in the exhaust. When the mixture detects a certain level of hydrocarbons, it indicates a potential leak in the engine's combustion chamber.

2. How accurate are engine combustion leak detectors?

Engine combustion leak detectors are highly accurate and can detect even small leaks in the combustion system. They are designed to detect combustion in the coolant that indicates a leak in the system, and they can detect leaks as small as 0.01 psi. They are also designed to be more sensitive than other leak detectors, making them even more accurate.

3. What color is the fluid in a combustion leak detector?

The fluid in a combustion leak detector is usually a bright blue or green. This color is designed to be easily visible to detect leaks from the combustion chamber. The fluid is also designed to react with the combustion gases, changing color to indicate the presence of a leak.

4. Where do engine combustion leaks normally come from when a failure has occurred?

Engine combustion leaks normally occur when there is a failure in the engine's cylinder heads or engine block. This can be caused by several issues, such as a blown head gasket, cracked head, pulled bolts or studs, and warped sealing surfaces. Each of these problems can cause the engine to leak exhaust gases into the cooling system, which can then be detected by a combustion leak detector.

5. How do you know when an EGR valve has failed and is not circulating combustion gases properly?

When an EGR valve has failed, it is often apparent from the symptoms a vehicle may experience. Engine misfires, stalling, rough idle, poor acceleration, and exhaust emissions that are higher than normal are all indicators of a possible EGR valve failure. 

Additionally, diagnostic tools such as an OBD-II scan tool can be used to detect a malfunctioning EGR valve. The scan tool will generate an error code that can be used to diagnose and repair the problem.

 Also, if the diaphragm fails when a hand vacuum pump draws vapors when attached to a vehicle vacuum line attached to an EGR valve. It allows combustion gases to escape externally into the atmosphere. Lastly, a pressure test of the exhaust system may be necessary to confirm a faulty EGR valve.
