seafoam works! [merged]

[cranky]

I have been using seafoam in heavy equipment engines for years and I have seen it make dramatic differences in performance and idle quality. I recently had a problem with low power from my 91 talon. It felt like the computer was removing timing. Normally what I do is find a secluded spot because you will smoke down your whole neighborhood. Start the engine and let it get up to opperating temp. I remove a vacum hose and put it in the can and rev the engine to about 2500 rpm and suck the can dry. Shut off the engine and let it sit for about 15 minutes. Then start it back up and run it down the road, and run it hard. This will remove a substantial amount of carbon build up from the combustion chambers.

Wow 17 pages and 4 years going strong, I have a 95 GSX and just broke 99k mile on it. I'll be putting in a can or two into the car. I didn't see anyone discuss this, but I do have a minor oil leak. We'll see if the SeaFoam makes it worse or not. I'll ###### change the oil and spark plugs after a week or so.

HydroLock, from seafoam? I figured if it was possible, then i should be the one to try.
Not really, i use this stuff all the time with no worries. 1 hour to do 1 can? no way like 5 minutes. The most extreme thing iv ever done with this stuff is took a whole can, took my plugs out and poured the entire can evenly ontop of the pistons, yes. the whole can.

Let it sit for 24 hours, put the plugs back in attempted to start it and nothing starts. So i take the plugs back out and their soaked get them clean do that a few more times. Finally starts up and holy crap, the most smoke iv ever seen from seafoam. My car runs extremely well with no side effects. If hydrolock with this stuff was possible, i think i would have experenced it. Is their even any reports of hydrolock from seafoam?
The most noticable thing iv seen with this stuff aftering doing the tops of my pistons. The oil.
When i change my oil it doesnt even look black, it looks like slightly used oil.
Clean, Clear & Under Control

SeaFoam, and any other incompressible fluid, can hydrolock an engine.

Hydrolock occurs when the volume of liquid in a cylinder is greater than the combustion chambers' volume. During the compression stroke the piston will reach a point where it attempts to compress the liquid, which of course it cannot, and cause horrible damage - bent connecting rods, shattered pistons, cracked block or head, severely lifted head, &c...

i have used seafoam alot i love it it works good.

 

[akira235]

the best place to pour seafoam is through the brake booster line, also, if you pour it in the crankcase you should change your oil after 200 miles, any sooner than that and it really won't do anything. from my experience, pouring it in the tank really doesn't help much, but 1 can of seafoam costs all of 7 dollars and some change and the difference is something serious.

It'd be tough to hydrolock a motor with Seafoam spraying from a spray bottle. I've sprayed continuously for 10 - 15 seconds at a time, no ill effects.

You want to use both the PVC port and/or blow off valve port and fuel pressure regulator port to get every cylinder equally. I used to use only the PVC port and couldn't figure why my knock wouldn't go away. Then I started running it thru the vacuum port for the fuel pressure regulator and the amount of smoke and carbon that came out was amazing.

I've submerged the piston tops before and Mityvacced the gunk back out, but its a pain in the rear and I don't think it all that necessary if you run 2 full bottles thru the intake and do it right.

 

[bmoha2]

I used the vacuum line that goes to the AFPR to suck it in slowly. I hadn't used it before. The Talon had 105k on it. I used a third of the bottle. I saw a bit of smoke start to come out the exhaust. I though well neat. Then to my surprise smoke started billowing out of the intake side of the motor. It was coming out the bottom of the intake manifold and from the throttle body. I'd say that is my boost leak I have been trying to track down! Looks like I need a new intake manifold gasket and throttle body gasket. It may be leaking from the throttle body pivot seal as well.

 

[No_Skillz]

Seafoam doesn't smoke unless burned. You certainly should not be getting any smoke coming out of your intake tract. Do a compression test.

 

[SD99GST]

^^^ very true, it's normal for smoke to be coming out of your exhaust manifold just because our cars get exhaust leaks often, but I have never heard of it out from around the intake manifold.

 

[bmoha2]

Looks like the Talon was smoking from the throttle body, intake manifold and the junction between the hi flo cat and the downpipe. I did a compression test not that long ago and the numbers were very good especially considering that it's a 12 year old car that has gotten the shit driven out of it on a regular basis. I don't remember the numbers. It was done by an ASE certified mechanic fiend of mine. I think he was more concerned with percentages than telling me the number. I have since driven the Talon thirty minutes or so and it is idling way better and seems smoother.

 

[98GSXtreme07]

It made my headgasket leak "more" noticeable...

 

[3tcpower]

When I have used seafoam it normally caused my car to run poor for around 20 minutes after changing the oil.....probably cause it left crap on the plugs. Other then that its always been fine afterwards.

FYI, it may be better to run it from the brake booster line. Just to avoid as many gaskets and junk as possible.

 

[bmoha2]

I am thinking it showed a messed up head gasket

 

[Captainredeyez]

When I used it, it showed me where me exhaust manifold was leaking.

 

[BenHooker]

I'm really interested in doing this, my car has terrible throttle response right now and I am trying to figure it out. Anyways, I know the basics, warm the car up, open the throttle to 2.5k, but where do I let the seafoam go in? I have a 420. Pics would be appreciated.

So this weekend, I had a blast with Seafoam... and let me say this... this stuff F$UCKING ROX!

I had a horrible diesel sounding idle, with backfires and stumbling all the while. I used seafoam, and like magic, the car is almost 100% working!

Now, the reason I say "almost" is that it did not delete 100% of my lifter tick...

So I was wondering, should I do this again? I would like to take my valve cover off and pour that shit ALL over my lifters and valve-train. Like almost a whole can. Then I would like to put even more into the cylinders...

The question ends up being:

Is there anything wrong about doing that? It wont hurt anything huh?

Also,

My fuel injectors ended up being the culprit i believe, so does anyone have any suggestions as to injector cleaning services?

Thanks!

 

[PIMking]

If you suck the seafoam through a vacume it will clean the injectors.

No dont remove the vc and pour a can all over the cams.

Suck it through a vacume and once the can is gone shut off the car for about 10 minuets and then start it up and drive around and have fun smoking out the area.

 

[Rob10_99]

If the chemical is in your oil, its every where in your engine. If you don't have 3g lifters I would suggest getting them for the pita tick issues.
To clean injectors will require it to go through the fuel lines. Cleaning the 'outside' of the injector will do almost nothing.
While your engine is clean inside, might as well not route your PCV valve back into the intake tract to dirty it up again. Get some type of catch can for it.

 

[treckin]

I already did/do all of this. I have the pcv vented already. I did suck it through the p-port, but there is no way, unless you have bad valve guides, for that shit to make it to the head.

Hey trekin,
Could you explain your idle numbers before and after the use of seafoam? My idle's at 2000 right now and I've replaced several things with no results. I might try seafoam.

 

[treckin]

well, it sounds like you have idle surge, so gl w/ that. Actual idle numbers were basically ok, it was more of a quality thing. i recommend seafoam no matter what though

 

[akira235]

I wouldn't specifically take the valve cover off to do it, but plenty of people pour seafoam into the crankcase via the oilcap.

 

[toofast82]

For the lifters, give Engine Restorer a try! it works wonders on 1g lifters

Great stuff. I use it in my 2G as well.

 

[toofast82]

Great stuff. I use it in my 2G as well.

I used it in my first dsm, a 90gst, and it shut it up. Someone told me with a dsm awhile back about it. My current one had some tick and phantom knock because of it and the engine restorer took care of it. I havent used it more than the one time on this engine and it continues to be silent
