Seafoaming my engine

Sorry about the spam of new threads, but i want to get a couple of problems taken care of asap

A friend of mine just finished seafoaming his car (lolpistons) and was telling me that theres a noticeable difference in throttle response, he suggested i try doing the same for my car. Can someone else thats done this to their car tell me how this works/actual benefits? My car has 97k on the engine and body and i don't think the previous owners took very good care of the engine.

It really depends on how bad your car is. There's a few ways it can go. I know some people live by it, and it works for rotaries as well, but it can also deliver the finishing blow to your car (like mine for instance). Carbon was keeping my rear rotor together and the seafoam just let my apex seal go. I would use it again (earlier though) if the chance came, it was already too late for my engine.

This is one of the things i'm afraid of happening.

Anyone else?

If you do enough searching you will find some who use water to remove carbon deposits.

Using water?...... I always thought using water will cause hydrolock.

rev the motor high and pour but in your case, it has to be sucked in via vacuum port or booster hose

first of all start with a search, then click advanced search button. Change the search filter to titles of threads then use "quotes to start and end your query" EXAMPLE: "seafoaming my engine"

here ya go, ur one time freebie.

^thanks.

Whats the difference between seafoam and this water treatment? Seafoam is supposed to help clean injectors as well right?

seafoam is cheaper at wal-mart than autozone. ad 1/3 in the gas tank, 1/3 in oil (100miles before oil chnage) and 1/3 via vacuum port. I've done both but I like water treatment better since tap water is free lol

Yeah, if I were you, do a compression check first before anything, mine was already low (~60 psi on all faces other than one on rear which read 20psi from what I thought was a stuck side seal due to carbon).

There's also ATF trick which some people use (poor few teaspoons for ATF in lower plug holes, crank few times with EGI out, sit over night, fire up). At least that's how I think it goes, just search any of this pretty much and you're bound to get some good results. That's what I did to choose weather or not to seafoam.

Too bad there aren't any wal-marts in my area :smh:

How can i access this vacuum port? I'll stress how retarded i am when it comes to things like this.

Thanks for all your help so far!

Most people will say the brake booster but I hear that only goes to the rear rotor. Can't remember which one I used :S

while speaking about the brake booster. I heard about it having to do with idle dropping when pressing the brake?

Whenever i depress the brake my idle will drop down a couple rpm. Maybe 100 or so? It might be my BAC also So many little problems with my car.

Could be BAC related or the vacuum hoses connected to the booster or it actually could be because of the voltage drop when the brakes are depressed.

I already know my BAC is messed up. 3k startup is funny, stalls when a/c is turned on, several other things.

You tried disconnecting it to see what happens? I don't have one, so I can't really a point of reference.

I would think alcohol would clean the crap out of the engine. Not the drinking kind...

But I don't think 'cleaning' the insides of your engine really helps anything. Its kinda like a creek where all the dirt and sediment is still in the river, but the water flows clear. You know what I mean?

Injectors, fuel filter, air filter, oil(s) & filter, coolant are more important to be clean/fresh.

Damn. And here I was going to suggest picking up a bottle of Wild Turkey.

That **** does a good job of cleaning ME out!

Srsly, though. I've never heard anything positive about running seafoam through our engines... Something about the apex seals....

I would say pull the vac-line on the backside of the UIM, T-off to a line that's about 18" long and drop it's open end into a 50/50 solution of WHITE (clear) rubbing alcohol and salt water.

Start the car and hold the tach at some rev that's higher than Cheech and Chong - like 6k, or something (dammit there's a write up for this).

If you've got enough volume (alot) it'll all eventually get pulled into the combustion chamber.

The reason this works is because it's super-heating the fluid and acting as a steam-cleaner, cooking off the carbon deposits, internally.

You don't want to be behind it while this is going on, either.... You'll not be liking life, if so.

Gigetty.

It's okay. Now that I go back and read it, I have the same thought.
