Can you use choke & carb cleaner to clean an intake manifold?

Question

If some of the solvent or the carbon deposits dissolve and go into the engine will it do damage to the engine is what I'd really like to know.

Answer 1

Gregory, There's a relatively new product on the market today that will do an exceptional job cleaning the carburetor, intake manifold, valves and most important, combustion chambers. It will not damage your cylinder walls or piston rings. We've been using it in customers cars for three months. I realize you do not have fuel injection but it does an excellent job in that area also.

NAPA and Car quest has it. 3M - Professional Fuel System Cleaner Tank Additive. Part # 08813.

Pour the entire 16 0z. white plastic can in your gas tank with a maximum of 15 gallons of fuel. It's the best of the best to date.

It's a little pricy @ $10.00 but you get what you pay for.

Answer 2

What you are doing is called super choking the car. Yes it will clean some of the carbon deposits out but it depends on what kind of car because some older cars Chrysler's for example have a crossover passage in the intake and if it's plugged the the manifold has to come off and be manually cleaned. No the carbon deposits going into the cylinder will not harm it as they will be vaporized and should come out the tailpipe as black air pollution. (smoke). Do not let the car stall while doing this though, as it tries to stall when choking it open the choke and feather the throttle to keep itrunning.

You should not let the car stall. GM used to make a product called Top Engine Cleaner available only at dealerships, this is pretty good stuff if you can find it, follow directions on can EXACTLY.

Answer 3

it won't hurt anything, just do it with the engine running, & slightly above an idle..
