Vacuum can get tricky and if not done right start sucking water from your bubbler or worse electrolyte out of the reservoir and will need to be controlled if it is to strong. This starts to get complicated. there are some cheap vacuum gauges like at Harbor Freight. Something you will need if you go this route.
Thanks myoldyourgold!
Ya, even though my camry's almost 12 years old, it has been good to me and I'd rather test on an older car than a newer one.
If I place the bubbler below the air intake like say 10", do you think I'd still have a problem with it sucking water/vapor into my manifold?
Also, what percentage of boric acid do you suggest in the bubbler?
