KA24DE + seafoam

[jpnissans13]

hey i have a KA24DE in my 91 240sx and i wanted to know the best way how to use the 16oz bottle. How much in the gas tank and how much in the vacuum line? And what vacuum line should i use?

Thanks!

I would do half on the tank and half on the Vaccume line.

I would choose a line from the intake so it cleans the chambers.

According to the instructions ON THE CAN:

Put 1/3 in your crankcase before you change your oil. Let the motor run for a few minutes, the drain it all and put in fresh oil.

Put 1/3 in the gas tank when you're getting ready to fill up.

Put 1/3 in the brake booster line, or just about any line leading to the intake. I like to put it directly in the throttle body, just so more of the manifold gets coated.

You're welcome, maybe search the forum or google next time, or just READ THE CAN.

DO NOT PURE IN THE CRANKCASE ( THIS WILL BREAK DOWN THE PROTECTIVE VISCOSITY OF THE OIL)

IT'S POSSIBLE THAT YOU MAY CAUSE DAMAGE TO THE ROTATIONAREY PARTS IN THE ENGINE DUE TO THE OIL BREAKING DOWN BY THE SEAFOAM!!!!!!!!!!!!!!

If you read his post you only run the engine for a few minutes before changing the oil. Also, this stuff is intended to be run in the crankcase as are many other cleaning additives. I'm sitting on 204k miles and have used this stuff in my car for years as a maintenance item. The can says to use 1/3 like posted above, but I actually use an entire can for each.

I know, I drove for a few hundred miles once when I first started putting it in my oil. Bad news.

So then if you know the reasults then why would you recomend it.... Live and Learn. just my 2cents. Don't mean to be as a** to you.

I personaly would not use the break boost line, It will suck too much fluid and possibly cause HydorLock. ( meaning bye bye KA) Try a small vaccume hose and when the engine starts pull the Fuse on the Fuelpump so that It runns on the SeaFoam till it runns out(your engine will cut out when it's empty)

The reason behind pulling the fuse after the engine starts is so that it Doesn't Run RICH. IT WILL BURN YOUR EYES IF IT RUNNS TOO RICH.

Whatever line you use, you shouldn't just dip the hose in the fluid. When shops do it they use something that almost looks like an IV, it drips it in slowly. The brake booster line has a lot of vacuum so you can hold the hose BARELY above the sea foam and it will slowly suck it in.

Either way, I don't think you can hydrolock your engine with a pure petroleum product. Hydro usually refers to water

correct but what I was mean is if you pore too much fluid in the combution chamber it can cause that b/c of the fluid not being able to be burnt.

Well, speaking from personal experience as I do this for a living we use the brake booster line quite frequently. Gm has their own product called top engine cleaner and it comes in a bottle thats around 16 oz. We do a top engine clean service that consists of getting the engine hot, start it up and pull the brake booster hose off, put the booster line in the bottle and tip it upside down to get the stuff in as quickly as possible, shut the engine off as soon as the bottle is empty, let the engine sit for 10 min, then start the car up and try not to die from the plume of smoke that comes out of the tail pipe, rev the engine up and down until the smoke starts to go away, take the car down the road and just run the $hit out of it for a few miles after it quits smoking, return to the shop and change the oil. Now, this service differs some from the seafoam treatment as it is only run through the intake and is not intended to be put in the tank as it will literally eat up the fuel pump and charcoal canister, nor is it intended to be put in the crankcase. Anyways, the point is there are 2 reasons that a can of seafoam, let alone 1/3 can will not even come close to hydrolocking an engine. First the entire contents of the can are barely enough to fill 1 cylinder let alone spread across 4 to 8 cylinders. Second, when introduced into the engine while running most of the fluid evaporates very quickly turning it into a fog which is compressable. We do have one of those dispensers here that looks like an iv and it is actually hooked up to the brake booster hose as well. I believe that I'm the only person that has ever used the dispenser and that was long long ago. Also, if you simply read the BACK OF THE CAN OF SEAFOAM it will tell you to introduce it into the intake in a steady stream while keeping the engine running, then when you come close to running out dump in the last bit quickly enough to stall the engine and let it sit for about 10 min before restarting. Now, I know that a lot of these products are not what they claim they are, but from a liability standpoint they wouldn't provide instructions that could cause engine damage or they'd be out of business pretty quickly from all of the lawsuits.

I recommended using it as instructed, not as I did. Big difference between 15 minutes and 100 miles.

WOW Great vid. poor slowly yea.............

[pmkls2]

I like the video, it gives very clear instructions on how to use the stuff, thanks for posting that. Also, on a personal note I like seafoam, I have owned my 240 for 7 years and have personally put 110k miles on it since then (204k total now) and I have used seafoam routinely since I have bought the car. Also, the deep creep penetrating lube is awesome. It really works well as a penetrating lube ( it puts WD40 to shame ) plus it is the same as what is in the pour bottle so you can use it to spray in throttle bodies etc.....

[SullivanRacing06]

you actually are supposed to use a dripper bottle, go to sears and ask them if you can see the induction service bottle they use, i have one, a friend took it from sears when he quit, it allows a small amout of fluid at a time,

great find
