Anyone using this cordless battery smoke machine?

Recommended Posts


I was thinking about buying this cordless smoke machine made by Autoline. I am trying to find false air coming in on 84 m10b18 L-Jetronic that is causing a high idle. Anyone else using this machine?  Here is the link:

Yeeps- not at that price!


Smoke's the trendy new (ok, not so new, just becoming popular)

to find air leaks in intake tracts.  It's a useful tool, but for older 

non- DI cars, it doesn't simulate the vacuum the intake experiences.


I have a $50 smoke pot off ePay and an air regulator, and it does well enough...

 A smoke machine is a very useful tool for a shop, mine has always had a couple of different ones----a higher-pressure one for finding boost leaks in turbocharged engines, and a low-pressure one for finding leaks in the evaporative emission control system for modern cars.


Since the average hobbyist probably won't use a smoke machine very often, you and a friend or two could split the purchase and pass it around as needed.


As for your 318i L-Jet engine, unmetered air usually causes a rough, low idle versus a high idle, but smoke testing is always a good idea. Remember to smoke-test the crankcase of the 318i engine----a cracked breather hose or even a missing oil dipstick seal can cause idle issues.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
