cleaning injectors?

[rich22]

I read the tech article on this site about cleaning injectors. It said to use brake cleaner. Is that really the stuff to use, or did they mean carb cleaner?

Brake cleaner. (or a couple bottles of Chevron Techron in your gas tank )

Anyone here had experience using Sea Foam

or the Chevron Techron product..

using this procedure?:
1)Put ~1/2 the can in the tank.
2) Suck remaining fluid in through a vacuum line under the hood.
3) You’ll need to keep the motor running by feathering the throttle cable while the fluid is being sucked in.
4) Stall the motor with the last of the cleaning fluid. (or shut off motor once fluid is gone)
5) Let set for 5-8 minutes.
6) Start car and take for drive.. it should smoke like hell for about 15 minutes.

Smoother idle and better fuel economy are said to result. Seems like some of the guys [on the other board] just swore by this exercise and were pleased with results.

Can anyone point out an appropriate vacuum line for an M42 motor?

Sucking pure fluids into a running engine sounds like a good way to hydro-lock a cylinder and crack a piston or head.

OK, hold on a second...

I meant for the injectors to be cleaned when they are REMOVED from the car..

Do not run Brake cleaner in your fuel tank!!!!!!!

Brake cleaner is usually tolulene or zylene, REALLY good at quickly cleaning out a fuel injector, You can use carb cleaner as well, but i found brake cleaner is a bit more effective. Be sure to use new fuel injector seals.

As for an in tank cleaner, I reccommend Lucas fuel injector cleaner or Techron

Very true if done improperly! Such as a large gulp of water in a fresh air intake duct.

But if done properly, and with the right chemichal ( which can sometimes be water ), you can actually clean the combustion chambers from heaving caking of carbon, or the sludge in an valve train.

The idea is to prevent your engine from ever needing this buy changing the oil regularly, running it through the RPM range every now and then, using decent fuel (not 2 month old low bid junk for the cheapest price, at a very slow gas station), and driving it.

Thanks, Jared. That's what I was asking about, cleaning them after removal, as your article explains.
