I'm very well aquainted with the search button and I've found very usefull information. Now a little verification just to make sure I don't *** myself out.

Here's the plan, please correct if need be.
1/3 Can to the crankcase.
1/3 Can to the brake booster.
1/3 Can to the gas tank.

After smoke clears, Change oil and filter.

After gas runs out, change plugs. or change plugs with oil???

So my main question is not what to do, but the exact order in which to do them. I'm not one to throw away a penny so i dont want any unnessicary problems from me not knowing what the hell i did to my car.

 

When you put it in the brake booster line, don't feed it way too fast, or you might hydrolock your engine. Be sure let the seafoam sit for 10 minutes after it enters through the brake vac lines. The seafoam in the gas tank should not mess with your plugs. You should change it after the white smoke clears out.

Don't drive too far with seafoam in your crank case.

 

sounds simple enuff but im still worried about my plugs thats the biggest concern, when should these be changed?? im planning on doing it soon anyway but i want to seafoam too so might as well get it in the right order.

 

i do the gas tank, crank case, then brake booster (with a friend to help) (brake booster should be last)

i was skeptical to use it bcs it looked harmful. but its basically idiot proof.
but after i have it all in. i let the car sit for 10minutes. then start the car, and rev the engine here and there to let the smoke burn out quicker. then after all the smoke is gone i drive it at high rpms straight to a shop to get my oil changed and such.

 

u can change the plugs after the when the oil is being changed. seafoam in the tank cleans the injectors n such. doesnt really harm the sparks enough.

or u can wait.

add seafoam when the tank is really low. and then u can fill gas.. makes it easier to mix n such.

 

seafoam is a bad idea...I wrecked my car the night after I seafoamed it...bad voodoo with that stuff...and it makes you wanna drive faster than you probably should be.

 

seafoam cured my SC400. I guess I got the good vudooo. lol

 

what was wrong with your sc400?
