If you want a good smoke machine for a good price, you should choose the OTC 6522 LeakTamer. It’s a kit of the most required tools for any type intake leak troubleshooting. The price is in the mid-range of smoke machines. If you do want an even better smoke machine and a bit more money to spend, you should choose the EWApro 2000E in my opinion. The price is double of the OTC smoke machine, but you will get a much better performance.
I do want an EVAP smoke machine for home usage, which one should I choose?
It depends on how much money you want to spend for your home usage. The cheapest in our list is the Smoke-Tek machine, but if you want more performance I would recommend you to choose the Autek SDT-206 machine. You have to spend a bit more on this machine, but in my opinion, it is absolutely worth it if you check what you get for the money. The Autek machine will give you everything you need for troubleshooting for a home usage.
How often do I have to refill the EVAP smoke machines?
It depends on what machine you choose and what type of oil it uses. It will take a lot of troubleshooting before you have to replace the oil, depending on the length of the smoke test. In my machine at my work, it takes around 10-15 smoke test before I have to refill it. In most of these smoke machines, you can also use normal baby oil, which is not so expensive. You should always double check with the manufacturer of the machine to find out if you can use baby oil in the machine.
What should I fill my smoke machine with?
Normally the smoke machines use a special oil in their machines. In many cases, you can fill the machine with baby oil instead. Double check with the manufacturer of the EVAP smoke machine to make sure it’s compatible with baby oil. If you can fill baby oil in it, the price for oil fill will get a lot lower.
How long time will it take to fill the intake with smoke?
It depends on the smoke machine and what volume setting you are using on your machine. To fill an intake and boost pipes, does normally just take a couple of seconds. If you are using it to find leaks on smaller hoses like EVAP hoses, it will just take a second to fill it with smoke. The most of these machines are pretty fast to fill it with smoke.
Is a smoke machine a good way to find EVAP and intake leaks?
It’s one of the best ways to fix EVAP and intake leaks in my opinion. I work as a diagnostic technician and I’m using these smoke machines for a daily use to troubleshoot my customer’s cars. Every time when I got a lean mixture, misfire, boost control trouble code, I start to check the intake with a smoke machine. If you have a workshop and are not using a smoke machine, I can really recommend you to get one, it solves a lot of problems which could be hard to find if you don’t have one.
Is it enough with 12v power to them?
Some machines use only 12v power and some use 110/230volt wall electrics, depending on the machine. Some of the machines use both 12 volts and 110/230 volt connector. You can take the 12-volt power from your car battery. Check the machine before you are buying it to make sure you get the right connectors and get information of how to wire it properly. Some does also required compressed air to work.
How to use an EVAP Smoke machine?
To use a smoke machine is very simple in the most cases and with the most machines. This is a general list of how to do it and you should always follow the instructions from the manufacturer when you are installing and using your smoke machine.
- Connect an adapter that will fit into the part you want to smoke test and make sure it fits tightly.
- Make sure you fill up the smoke machine with oil and other required additives
- Connect your power resource, either on your car battery 12-volt power or 110/220volt supply. Some smoke machines have both of the powers. Some will also require compressed air.
- Start/Activate your smoke machine.
- Check for any signs of leaks around all important parts. Some smoke machines have UV in the smoke, so you can use a UV light to check for any leaks.
What kind of trouble codes can you diagnose with a smoke machine?
You can diagnose the most kind of trouble codes with a smoke machine. Normally you use it to detect EVAP leaks and turbo boost pipes leaks. It’s also perfect to find any leaks around the intake or the exhaust pipe. If you have any lean or rich mixture trouble codes, you should always use an evap smoke machine to find any leaks fast.
Misfire codes could also be caused by intake or boost leaks and should be diagnosed with a smoke machine. Turbo boost control problems are often caused by worn out turbo boost pipes, and a smoke machine will help you to find the problem really fast.
So, intake and EVAP leaks can cause a lot of different trouble codes and it’s a very good starting point to start checking with a smoke machine the first thing you do. Air leaks can be really hard to identify and can cause serious problems and a lot of trouble codes. I use an EVAP smoke machine on almost every trouble code I get when I’m finding problems on vehicles.
How does an EVAP smoke machine work?
A smoke machine uses a heater inbuilt and evaporates the special oil or the baby oil to smoke. It does then push it into the area which you want to leak test. Smoke machines can detect micro leaks below 0.010″ inch and some of them does also have the ability to inject UV additives to the smoke, to check really small leakages with a UV light.
The heater inside the EVAP smoke machine is either ran by 12-volt power or 110/220 volt power. Some smoke machines does also use compressed air to push it into the test area. Some have an aircompressor inbuilt for this task.
- It is big price differences in smoke machines, but as with a lot of items, you will often get what you pay for. It’s the same case with EVAP smoke machines.
- You can often fill Baby oil in these machines to create smoke. Check with the manufacturer of the machine before filling it with baby oil. Filling your machine with baby oil can damage the machine if it’s not compatible with it. Better safe than sorry.
- An EVAP smoke machine is one of the best ways to find a mixture, EVAP and boost related trouble codes, I use one myself for a daily basis. You can solve a lot of different trouble codes with a smoke machine and it will absolutely save you a lot of time on troubleshooting if you don’t have one already.
