Excelente producto lo recomiendo mucho solo que tienes que comprar aceite no viene incluido


Immediately found my EVAP leak on the 08 Jeep and fixed for less than $5. Works as advertised.

80 bucks to keep me from guessing at random gaskets. Life changer

Using this for a LS swapped truck with aftermarket standalone harness and ecu. The typical “spray carb cleaner at the sensors” trick wouldn’t work because the system is self learning. I knew I had a leak somewhere but had no idea where, and aside from buying smoke bombs to put in the intake I had no idea how to find said leak.
This little machine is the cheaper of the two listed but I’m thankful I purchased it.

At first it wouldn’t produce smoke, I removed the “fill” cap and put my finger over the smoke tube to burp it. That seemed to work because my engine bay got so Smokey afterwards I had to re-think my way of testing.

Unfortunately my only gripe is that the rubber cone isn’t large enough to fit on the throttle body I have. I suspect it would work on factory intake tubes though. Nonetheless, a bit of ducttape did me a favor.

I highly recommend this machine. I’m sure I’ll use it again sometime in the future. If not, I’m sure I’ll get most of my money back for it on Craigslist.

**mine did not come with oil. Be prepared to “borrow” your wife’s baby oil.

All in one combo is sweet

Works well enough

Works well for the price, will get you by.
Don't overfill the oil reservoir though or it won't produce very much smoke.
