sea foam on an lt1

Is this good to do or not... I only have the regular can... not the deepcreep... I wont be able to put it in my gas either... I was only going to hook it up to the brake booster and do that only.. If i do it can i just do the one part or do i need to do all of it? Is it good for the engine?? Even an 82000 mile engine?? would it clean the combustion chamber??

its the IAC sensor you are thinking of and if anything it would help that sensor out but realistically the seafoam would never touch it. also, i dunno what the hype is about seafoam anyway. sure it looks cool smoking up your neighborhood but all anybody ever says is just what the guy before them said.. .no real proof that is really works that ive ever seen.

Park car in a well-ventilated area.
Start car and run until it reaches closed loop (generally 5-10 minutes, and above 160°).
Open hood.
Find black hose that runs from the middle of the driver's side of the intake manifold into the black box on the firewall. This is the brake booster hose.
Remove the hose end from the black box; you'll hear the vacuum and the car's idle change.
If your car stalls out, then use the middle hose that attaches to the passenger side of the throttle body. It's an L-shaped piece of hose, that connects to a black box mounted on the pass. side of the intake manifold. Pull the end connected to that box, and use that for sucking the liquid in, detailed below.
Place end of hose into the top of the Carbon Cleaner bottle. Allow it to suck liquid out until the engine starts to idle noticeably lower; then remove the hose from the bottle. Do not pour enough to stall the engine yet.
Warning: Sea Foam does not recommend sticking a vacuum line into the bottle, but rather pouring the liquid into the line by using your thumb over the top of the bottle to regulate the flow. This prevents too much liquid from being drawn in and possible hydro-locking. It is your choice how to do it, at your own risk.
Repeat the above until between 1/3 and 1/2 of the liquid has been used.
Now let enough of the liquid be sucked in until it stalls the engine.
Turn off ignition.
Replace black hose end into brake master cylinder (the black box on the firewall).
If you used the throttle body connection, reconnect it back to the black box.
Pour the remaining 2/3-1/2 of Carbon Cleaner into crankcase (through the oil filler tube). If you want to be exact per its instructions, you can measure out about 7.5 ounces to add to a full oil supply of 5 quarts. This turns out to be between 1/3 and 1/2 of the can.
Pour other full bottle of Carbon Cleaner liquid into gas tank.
Remove intake bellows from throttle body and push up out of the way.
Have someone (or something) press the gas pedal all the way down, or manually move the throttle cable assembly under the hood, until the throttle blades are fully open.
Spray Sea Foam Deep Creep into throttle body, fully soaking the blades, the bottom, top, and up and down into the intake manifold behind the throttle body. Use a good amount.
Wipe off excess liquid and visible deposits from the throttle body and blades with a shop or paper towel (especially around the edges of the blades), and reconnect intake bellows.
Let car sit for a total of 15 minutes from the point you stalled the engine (however much of the 15 minutes is left after you've done steps 9-16).
Start car (it will be harder than normal).
Immediately take the car for a spirited drive, being sure to rev high as well as put a load on the engine to make best use of the Sea Foam in the oil valleys and lifter and ring areas. Enjoy the fogging of your neighborhood. Then take it to the gas station and fill up the tank with 91+ octane (as always

Damn man people have already wrote up guides for seafoam... I'm thinking it's good sheet. The only way it will hurt something is if you have so much freaking gunk in your engine that some gunk gets stuck on the o2 sensor and messes it up. Me being as paranoid as I am did not want to ruin my under 5k o2's so just as a precaution I put my old ones back in when I ran the seafoam. As usual I wasted my time but it gave me a piece of mind

I used it as described and it seemed to help quite a bit. I used the brake booster line with a small funnel to pour it in.

I used some Berryman's B-12 Chemtool as well to help clean the throttle body blades. The Deep Creep probably just works slower, but it wasn't cutting the gunk. The B-12 cut right through.

It really didn't fog all that much. However, I attended a track day at Texas Motor Speedway last Friday which blew out the rest of the carbon. It's amazing what 5000 RPM for extended periods will blow out

It was running clean after a couple of sessions.

I used Seafoam and it caused both of my O2's to go out, although many people have done this with no ill effects. I probably won't be using it again unless for some reason I have to change out the O2's again. I personally think it's more hype than anything else, although some swear by it.
