Get an 8 foot section of small diameter hose and connect it to the source for the VIAS vacuum tank. Then you can sit comfortably in the driver's seat, keeping the RPM's at 2000 while slurping up the Seafoam. This approach works very well. The little hose fits easily into the narrow neck on the Seafoam can, and you don't run the risk of gulping up too much at once.

If you have a 5th gen you can do that manually by pulling on the throttle lever/cable.

Funny thing, I started this thread last year when I first tried it, and just recently I did it yet again and there was little to no smoke coming out of my exhaust, so I guess that solidifies my claim!

I suppose there are a lot of things I could do if I had 3 hands.

you should really go as close to the throttle body as possible however on the 3.0 that's not really possible

Well...I did it yesterday, but I put half of the can in my fuel and half in my oil. None thru the vacuum lines. Needless to say...NOTHING happened. Today I'm going to buy another bottle and run 1/3 of it thru my vacuum line. I'll let you know what happens tomorrow.

Where is location on the 00? Thanks.

Beats me. The 5.0 gen VIAS is different. Try the brake booster. Larger hose, same concept.

There was a thread/write-up a few months back from someone who used a long length of hose from the brake booster, and did this from the driver's seat. It's what gave me the idea to use the VIAS vacuum source, which I think is tons easier to do. But you're right, the 3.0 liter is different.

Thanks. I really like your battery tie down...

You won't see any smoke if you add the seafoam to the engine oil and gasoline tank. Adding the seafoam into a vacuum line that feeds "All the intake valves" will get the smoke from the tailpipe.

1/3 to gas tank
1/3 to engine oil (then change oil 200-300 miles later)
1/3 to vacuum line feeding intake valves

Would this help with the warm start issue?

If your mechanically inclined and like the idea of better gas mileage and throttle response for 10 bucks its obvious you should take advantage of it. asking why to something like that is like asking why should i buy an HDTV when my tube tv works just fine... or why should i buy the skippy peanut butter that tastes great vs the pathmark stuff thats just "edible". or why should i buy gas from mobil/hess/shell when theres a cheaper watered down gas at "usa petroleum" down the block. I bet you run 87 dont you? MY point is you dont have to use any of this stuff, if you want your car to run like garbage. My girlfriend says her sentra runs great too, but then i ask her what that burning smell is and her response is "oh it always does that". lol.


ummm... I use techron all the time, stuff works great. theres obviously something else wrong with your car.


the only problems that occur have been o2 sensors throwing a ses code for a short while due to all the crap being flushed out of your dirty engine at once... nothing to write home about imo.

I'm gettin this on my way home tonite and given it a try. I have bit of stumble at warm idle, and pretty bad gas mileage, so we will see if it helps. I'm an 02 6mt, with just under 200 0000kms, for $10 it's worth a try

Hi,

I just figured that I would add some fuel to the fire...

I worked at GM dealerships during the 1980 & 1990's and GM had some TSB's regarding the use of GM Top Engine Cleaner for cure some symptoms...

On 151ci Iron Duke engines to reduce ping by removing carbon from the combustion chambers and on the 350ci GM (Oldsmobile) diesel engine for sticking rings (removed pre-heaters on a hot engine and poured Top Engine Cleaner into the cylinders by way of the pre-heater hole)...

For using this product the correct usage was to pour in or suck in from a vacuum source 1/3 or the can as fast as possible and keep the engine from stalling by opening the throttle....

The faster pour, the better and then increase the pour to stall the engine, turn the key off and allow the engine to sit overnight (12 hours) with the cleaner in the combustion chambers.....Start the engine the next day and pour or suck the rest of the can into the engine.....

Allow the engine to warm and drive a short distance and than change the oil & filter because the cleaner left to sit in the cylinders will work its way down into the oil....

I had a Chevrolet Suburban that was used to tow my race car that had its life extended about 30,000 miles because using Top Engine Cleaner would free up the oil rings and cut down on oil consumption until I rebuilt the 350ci engine...

In the past the GM Top Engine Cleaner did work, but probably the EPA removed all of the ingredients that worked...

I have no information or position on the use of Seafoam or BG44, only that the use of an effective Top Engine Cleaner can be beneficial...

seafoam works great imo i have used it on boats cars lawnmowers etc...

indeed it is!

holymoly

wow after going through 4 pages of lots of trashtalk, I have a 4th gen Maxima with 180K miles.

To put some seafoam into the intake manifold, do I disconnect any vacuum hose or open the PCV value as pour some in there as per this video.

ivey_usmc

Im going to try this today and see how it goes.

holymoly

I put one third in the oil and one third in the intake manifold and one third in the gas tank.

Had a warm engine and hit the RPMs to 6000.

But no smoke at all. Nothing.

Have to feed the seafoam into the intake manifold a little at a time then turn off the engine for a few minutes. When you start the engine you'll get the smoke.

As mentioned you do have to draw it in slowly into the intake and then turn the car off for a few minutes and then restart. You mentioned that you put 1/3 of the can in the oil crank cases so you will need to do an oil changed as the seafoam mixture will thin down your oil it can NOT be left in there for a drive cycle.

IndianScout

I've tried SeaFoam 2x now with 0 results, that's enough for me, I always use the brake booster method

holymoly

still no smoke. Maybe my max already had it's colon cleansed?


Really, and I just changed my oil.

Anyone agree?

Christobal65

Yes you must change your oil fairly soon otherwise the oil will be too thin to protect the engine. When you do drive with the seafoam in there i would not drive fast or hard at all, just gentle cruising and acceleration.

Ghost_54

iTrader: (13)

Yes this must be done withing 50 km of adding seafoam to the crank case, that is why most guys would perform a full seafoam treatment followed by an oil change. I am sorry you didn't know this and now have the expense of an additional oil change, but I am glad you at least posted what you had done using the seafoam and save you a major engine problem.

holymoly

I can damage the engine? Already driven 100 km.

OK just changed it. It was running a bit rough.

thanks
