Anyone try Seafoam?
 

So my G has a lots of miles now and I'm thinking of doing a seafoam flush. Do you guys know if this is safe for our cars? Will it foul up spark plugs or o2 sensors? What's also the best method of applying it? I was thinking through the pcv connectors leading to the manifold.

I did the sea foam flush on my 03 Acura CL.....and we used a small funnel, and fed it SLOWLY thru a suction line by the throttle (careful, she will try and stall, so work the throttle by hand). We put in an entire bottle, let the car sit for 15-30 minutes, and LMAO, the smog was so thick, people thought my townhouse was on fire and called the fire department.

I use seafoam on all my cars, I get two bottles

1-Turn your car on

2-take off your brake booster hose(this works like a vacuum)

3-Very slowly pour it into the brake booster hose, the suction will want to chug it down but do it very slowly not to drown the engine and hydro lock it

4-After you get about half the bottle emptied into the engine turn it off and empty the other half into a full tank of gas

5-Wait about 30 minutes for the sea foam to break down some of the carbon build up

6-Turn your engine on. Your engine might stall or run very boggy when you turn it back on and it could even misfire and throw a code, but let it run for 5 min

7- Go for a spirited drive on an open road(you will fill up your street with a smoke screen)

8-Drive your car around for about 10 min or until the smoke goes away

9-If your oil change is coming up then you can use half of the second bottle to treat the crank case(make sure you get the oil change done between 100-150 miles of the crank case being treated)

if your car throws your an engine code just do the ecu reset

do you guys want me to do a DIY?

yes please, thatd be great

^what he said

I have one suggestion when doing the part with the vacuum line. Instead of pouring it in, put the amount of seafoam you need in a clear container and let the vacuum suck it up, its far more controlled.

^thats one of the worst ways to do it, you'd hydro lock the engine like that. You have to let the vacuum sip on the sea foam.I just got back from work. I'll make the DIY when I get up

^^ THIS ^^

YOU HAVE TO BE CAREFULL NOT TO HYDRO LOCK YOUR ENGINE WITH THIS STUFF.....the trick is a little at a time in a vacuum line (AKA- sipping thru)

Am I nuts or did you just say he was wrong and then proceed to say to do it exactly the same why he did?

OP, yes Seaform treatment is effective. I've used it in the fuel tank, upper cylinders, and crank case. As was stated, it is extremely important to induce it very slowly into the upper cylinders through a vacuum line. I chose the brake booster line. Don't do it inside a garage, it will smoke like a house fire. Use the correct amounts. There are videos by Seafoam that you can find on Youtube to see the proper way to do it.

where is this brake booster line?Cant I feed it through pcv line?

Brake booster line is connected to the brake booster. Open the brake fluid compartment cover. Just to the left of the brake fluid reservoir, there is a hose about 1/2" or so. Use pliers and disconnect the end from he brake booster (the big round black thing that its connected to). There will be suction. Suck it in here like a straw. Very slowly. Your engine might stumble and start to send horrific smoke out of your tail pipe. Don't worry, that's normal. Don't suck it up so fast that it stalls the engine.

I tried, but my brake booster line is extremely tight!! after i took off the clamp i could not get it free i did this on my g35 and it was so easyy! i almost pulled the whole thing out i put so much strength in to it.. then i gave up before i messed something up.. :icon43:

It is on there pretty tight. After removing the clamp spray a little PB blaster on the end of thew hose and five it ta few minutes. Then grip that thing like it's your pecker on a lonely Saturday night an pull firmly but gently. It'll come off. Be careful not to break the nipple it's connected to, I don't know how hard that is to replace but probably not easy.

Or just find another vacuum line that feeds to all cylinders.

bahahahahah I feel like such a n00b thats pretty much the same thing ahhahahaa. When you have to deal with drunks all night you get super tired, my bad buddy. Thx for pointing it out BB. Are you gonna make the DIY since you know everything about seafoam or should I :bowdown:

thanks for the input, ill give it another try!
