Yeah, pour it slow and steady, let it sit for however long you can be patient for, and turn your truck over and get away cuz it will smoke the roaches out of an apartment.

 

And this will not clog the cat?

 

At my shop we use an IV like drip that slowly goes through the brake booster tube. We also have the car run at about 2000rpm so it runs through smoother and doesn;t stall (also so it doesn;t take as long (Important when you only get paid commision))

 

The best results I've had so far have been to suck Seafoam through the brake booster line. The stuff does wonders in there! I sucked a whole can into the brake booster line, let it run, smoked out the neighborhood, and shut off the engine. I started it up again, smoked out the neighborhood once more, and shut the truck off. In an attempt to disperse the smoke from the tailpipe, I placed a box fan next to the tailpipe, started the truck, and throroughly dispersed thick smoke evenly throughout the neighborhood. Finally, I just got fed up and decided that smoking out the neighborhood wasn't good enough; the whole town needed to be smoked out! So, I kissed the wife goodbye, and drove the truck down the street to the interstate, smoking all the way - I was beginning to think I needed to get my truck on the patch or the gum, because it was smoking so much!

After about 20 minutes of driving, I got back home - and the truck was running nice and clean. Shortly afterward I determined that most of the smoke I had seen was the oil pooled up in the intake plenum that I had spotted a couple of days before, so no real benefit has happened yet.

I don't regret it, though. Seafoam works wonders in everything. I've seen a gunked up Edelbrock carb go from nasty and gunked up to smoothly operating just because of this stuff.

 

No, you will be good.

 

We used to do something like this at Big O. I don't remember what it was, but we had a tank that we could pour a bottle of seafoam into, and then pressurize it with a schrader valve. Then we'd dump another can in the gas tank, and then hook up the pressurized seafoam to the brake booster line... and I'd start the vehicle, and hold her at about 2500 rpms, and one of the other dudes would pop the valve on the pressure, and WHAM. The cars would almost always try to stall out. They'd smoke for a good 20-30 minutes... and I never noticed any improvement. I think I still might try some MCCC in my truck though. If I can afford it.

 

SEAFOAM is awesome. you will feel a difference. it cleans much better than any fuel system cleaner ever could. you DEFINATELY want to use it through the brake booster vacuum line. it breaks up alot of the carbon in your engine to make it run more efficiently. I've had an irratic(sp?) idle and sputtering engine, used this and it cleared it right up. the way i use it is, start the truck, pull off the brake vacuum line,get a small funnel and push the end into the brake booster vacuum line. pour it in very slowly so as not to stall the engine. i usually use about half this way then the other half in the gas tank. after putting it through the vacuum line, shut the truck off and wait five minutes. rehook the vacuum line and start it up. i usually bring the rpm up to about 2,000for a few minutes.depending on how much gunk was in your engine, it should smoke like a *****' for a few minutes. ( this is really cool and sometimes ticks off the neighbors[sm=icon_sneaky.gif])then take it for a ride, kinda beating on it to help blow all the crap out of it. it's a good product that i've had very surprising results with.

 

What ever you use its better if you let it sit. 5 mins is not long enough to soften or dissolve carbon. let it sit 3-4 hours or over night if you can. You'll get better cleaning and better results this way.

 

The official Mopar Combustion Chamber Conditioner
is not expensive at about $6 per can
and works better than Seafoam.

Throttle response and 'feel' of the engine will be better after carbon cleaning
but expect the MPG to actually go down on the next few tanks
after a carbon cleaning....because the carbon deposits
raise the "effective" compression ratio
compared to bare clean metal.

 

So do i leave the engine running, then take off the brake booster line, and pour it in while its running? then when its done going in i jsut let it sit overnight?
