Sea Foam Question K i'm gonna race in the drags tomorrow night but I need to get rid of some pinging bad (which I think is mostly due to bad gas :complain: ) First question: should I run it through the fuel tank or straight into the crank? If I do run it through the crank, where do I put it in? A detailed discription, or even better, picture would be appreciated. Is it safe to drag with Sea Foam running through your car? Oh yah... I just installed a new fuel filter if that has any bearing on the situation. Thanks!

Pull the brake booster line off the brake booster, and pour it in that line while the car is idling. You may need a friend to attend to the gas pedal so that you don't stall it putting the cleaner in.
I'd let it sit overnight if at all possible, or atleast for a few hours so it has a good chance to break everything up in your engine. But I would recomend changing your oil BEFORE you go to the dragstrip. I know it doesn't say it on the bottle, but w/ GM Top end cleaner your supposed to change your oil after running it, and seafoam does the same job, so if it did thin out your oil, I'd hate to run it a few passes at the track

its the rubber hose that is connected to a big black hemisphere looking thing DIRECTLY behind your brake fluid resevoir. So in the back of the engine bay, on the drivers side.

Like they said, the correct way to do it is add seafoam into your brake booster line. It is possible to keep the engine running by yourself, the throttle cable is right there next to you. Otherwise, have a buddy do it for you.
You want to add approx. half of the seafoam in while you keep the engine idling, then dump the rest in and let it die. Let it sit for awhile, ideally overnight. Change your oil after you add seafoam! It does have an added lubrication agent, but it's best to change your oil anyhow.
As FstBlkZ28 said, I wouldn't want to run on thinned out oil at the drags either!
Now on another note, Seafoam probably won't solve that pinging problem. It will help if there's a lot of carbon buildup in your engine, but thats about it. Bad gas may be your problem, do you run 93 octane? It says in your sig you were pinging at the dyno as well.
I'd guess that hypertech programmer the previous owner installed is causing it. You should be able to run fine on 93, no pinging at all. The tune they programmed is probably too radical.
Just a few things to look into

I would never let it sit over night, nor would I let it kill the engine by flooding it. On the bottle it says let sit for, what, like 5 minutes, and then it says only pour half the bottle in. I think you could end up with potential problems by doing it this way.

My proof: When i had my head off, i had a HUGE amount of carbon build up on top of my pistons, so i poured some seafoam in the cylinders and let it sit for 20 minutes. Soaked it up, and then tryed rubbing the carbon .... barely even put a dent in the carbon build up. Whether or not a full night would do any better ... who knows

alot of the dakota guys pour it down the TB, add to oil, gastank, and down a vacuum line. anyone know if it's true that seafoam can break apart too much sludge and clog up the oil system? i hear some people remove the oil pan after seafoam and notice a ton of sludge that has settled down.

We built a 306ci heads/cam small block Ford for my buddy a couple of months ago. Previously we had run Seafoam through the motor after we tuned the car up.
The block was actually out of a '79, and we didn't notice any sludge in the motor at all when we tore it apart. Which was actually pretty surprising...
I don't know if sludge build up is common after using Seafoam. I didn't notice it, but people use that stuff so many different ways.
Just make sure you change your oil afterwards.

WIll do and thanks for all the advice. I ran the car last night - it was still pinging - but not nearly as bad w/ the 100 in there... (only put 1/2 of the Sea Foam in the gas tank earlier that day... then it was off to get some 100 octane race fuel to even out the $hitty 91 - no 93 in cali or nevada). Car had minimal pinging after I gave it a few jumps to 5.5k RPMs and after it got the 100 mixing around in there.... once that 100 gets in there it starts purrin... then I get a lead foot...

Pinging is the result of a serious problem. I would not run the car at a track with a pinging condition. Hell - I would not drive the car with a pinging condition!
You may have too much ignition timming in your tune up. Or your running **** gas. Either way, pinging will burn valves and pistons, so get it fixed.... before your motor goes POW!

Hello.
Just to pipe in here, I have used GM Top Engine Cleaner about a dozen times now on various cars, including my LS1.
I usually pour it in through the TB, slowly, and turn the car off myself after the can is empty. I have only let the Cleaner kill the engine once, and it was on a Cavalier... it started up just fine after 20min.
Also, I usually let the Cleaner sit for 15-20 minutes or so. I have never heard about leaving it overnight.
