Driving with an EVAP System Leak – Is it Safe?
We recently took an in-depth look at some of the best EVAP smoke machines on the market.
If you own one of these machines and use it to periodically check your vehicle for leaks, you could end up in a situation of knowing you have a problem but need to drive your vehicle before you can get it fixed.
Is this safe you may ask?
The answer is relatively simple; you and your car should come to no harm, however, you are causing more pollution and your vehicle will not pass any future tests while it is in its current conditions.
So while you may drive your car, the best course of action is to see the leak as soon as you can.
What about if I don’t have an EVAP smoke machine? How can I tell if there’s a leak?
The most obvious solution to this is to have your vehicle checked out with a service.
However, before you give your nearest auto-shop a call, there are some small troubleshooting tips you can carry out if you don’t have access to an EVAP smoke machine.
- The Check Engine Light may come on while you are driving, (this could be accompanied by a smell of fuel). If you have recently filled up the car, you should check that the gas cap has been fixed back into place properly.
- If the cap is tight and you still have a check engine sign or can smell fuel, you could have a leak. This could come from all manner of areas within the EVAP system; faulty vent o-rings, and defective purge valves are a common source of leaks.
- Remember, if you have a leak, it will be leaking emissions even when you are not driving. Do a smell test after your car has been parked for a while; if you still detect an aroma of fuel, your EVAP system may well be faulty.
- If after these troubleshooting tips you suspect that your EVAP system has sprung a leak, it is time to call your mechanic. They will be able to find the source of the problem with an EVAP smoke machine. From there they will be able to fix it for you.
