alright so i did it! I took some pictures, just in case if people want to see where the brake booster..

Instructions by unknowndesi :

I Did not get CEL light but if you do video is included on how to reset ecu!
Use seafoam to break down some of the carbon build up!

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!

Now is where everything is located!

Thanks Bb, with PB blaster taking the hose was much easier.



Location of Brake booster


Take the hose off from the booster


Slowly Feed the seafoam to the brake booster hose.


Video..

 

OK, I'll bite. What is "Seafoam"? What did the video show us?

 

Good stuff. I've used this on my G37 before and thinking about doing it again. Did you leave your car off for a while to let the seafoam do its cleaning? Might want to add that to the instructions.

From my research, most people recommend siphoning half the bottle through the intake vacuum and dump the other half into the gas tank.

 

What is the average mileage seafoam should be used?

 

How much did you use when you did this?
Did it throw any CELs when you started your car?
How about when you were actually putting the seafoam in?
What is the benefit of doing this?

Please elaborate on your DIY a little.

Thanks.

Nice write up, bahahahah

 

Thanks for taking your time to write this diy

 

unknowndesi I did give you credit for the write up.. I basically just included pictures on the top it says "Instructions By: unknowndesi"

 

i still a wuss when it comes to this, too scared to try it

 

Ive used seafoam before in previous cars but not the G yet. Does anyone have proof that it really works though? i understand it makes a cool smoke show and LOOKS like it works but idk

 

Plan on doing this this weekend. How good were the results?

 

I Need help, I try to find the same bottle like in the picture in the pepboys, but they only have spray?? They have a liquid one but in a size of a galon... and I dont need that much that cost me 30 bucks.....what should I do? Just spray it out then let it suck in from the container????>.>
