Ok. I wanted to see what the whole big deal about Seafoam was so i went and bought 2 bottles @ ~$4 each.

Step 1: Went home to change the oil.

The engine (NA y8 w/ ~90k) was still pretty warm so i let it cool for a bit.

I first put about a 1/3 bottle in the crank:



Step 2: I disconnected my brake booster line and SLOWLY :!: poured in the remaining 2/3 bottle WITH the car running. Sometimes it would sputter and start to die but just slow down the pouring and it'll catch back up. *Some smoking may occur*

This is the line i used.



Step 3: i poured the other bottle into my gas w/ about a 1/2 tank. Yes i know this is too much. I believe this was a reason why i was running hot the other night when i was just sitting around ina parking lot w/ my car running. Not TOO hot.. but warmer than normal.. about 2/3 up the gauge.

Now this is where i think i messed up. The bottle says to let it sit "OFF" for about 5-10 min. I didn't do this. *i did rev a bit while i was Seafoaming through the brake booster. This was all the smoke i got....




I then went for a "spirited" drive down my road.

No huge smoke clouds, no problems... It seemed to run a bit smoother and a bit quieter..

I"ve heard that Seafoaming will foul your plugs... so i pulled all of mine and checked. No different than normal. All 4 looked the same.. *i cleaned 'em w/ carb cleaner anyways..



I returned from about a 15min. drive and changed the oil. Then refilled w/ Castrol GTX StartUp 10w40.




All Done!





This is the next Seafoam Project to go under. 1985 Toyota pickup w/ 256k original miles on the odo. I'm gonna do this on spring break. I'm trying to find gaskets for valvecover and a cheap ass headgasket b/c i'm gonna pull all of em before and after and see how well this stuff works.



i'm not scared of f'in this engine up. It runs but no insurance on it b/c its jsut a "work" truck. As you can tell by the flat tires it really sees alot of "work"

Thats all for now.. sorry for the book

 

Seafoam :thinking:

 

cleans out the engine

 

Sounds awfully odd. To be pouring the contents of this bottle into everything for your motor...

 

go to htech and look up seafoam, most of dem boys use it and swears by it. me and friend used it first hand in his 87 civic hatch and it made it ran smoother, more quieter, and the idle was overall smooth and level.

 

Yeah I use Seafoam on all my cars. 1/3 bottle through the intake, 1/3 bottle in crankcase, and 1/3 bottle in the fuel. Then you go WOT all over the place. It will create a TON of white smoke behind you, but it basically burns off all the deposits in your motor. I think its made of petrolium so it makes your car run insane hot, so thats how it burns off the deposits. Make sure you change your oil after the treatment

 

Why did you use 10-40?

Do you notice much improvement from this?

 

we did it on my friends accord, clouds of black smoke were rolling down the street. after we changed the oil and the spark plugs, the car ran better and the idle was much smoother. im wondering if it works the same on a turbod motor

 

You're not really suppose to run the car with this in your crankcase. It thins out you oil and releases all the junk in there. You dont want that running through the car. You're suppose to let it idle in the crankcase for like 5 minutes and then change the oil.
You let the seafoam sit in the TB for 5 minutes to let it break down the carbon deposits, which are all then burnt up when you fire her up for a spritited drive. You can smell the difference when the carbon burns. Do a search, there's tons of info on here. You may also want to remove your intake piping and clean the butterfly better with a brush and some sefoam, or carb cleaner.

 

PS. The carbon burns white... black smoke.. you got problems with the car.
