Seafoam

Found out this morning that Seafoam has more uses than I originally thought. Pulled off the vacuum line to the brake booster, and began pouring it in. Instant steam inside the engine compartment. Finally found that exhaust leak I though I had been hearing. The seafoam actually wets the area that is leaking, so it is very easy to detect. I know this is not a great discovery, but it may help some other people out there with an annoying exhaust leak that is difficult to find.

Chris

You know when I ran Seafoam through my 90 there was steam coming from the PS of the engine. It was dark so I could not see where it was coming from, I will have to run it through again.

I would be wary of this product. I know a lot of people have had good experience with Seafoam, but a good friend of mine had a rough idling Range Rover and I mentioned what you guys said about Seafoam and its effectiveness. He tried it and a couple of days later blew a head gasket on the Mass Pike. It could be completely unrelated, but it seems a bit suspect. Just an FYI.

I have to agree with Chris. Seems like solving the symptoms and not the problem. Just sounds problematic to me...

I have a 4.0 with 172,000 miles that has never had a valve job. It needs one, but I will probably replace the engine before I pay for a valve job. Truck ran noticeably better after using the seafoam a couple of times. I seriously doubt this stuff would cause a head gasket to blow.

Same here. 170+K on a 3.9 that was idling rough. Checked hoses and stepper. Poured in some seafoam and it's evened out, mostly. Not perfect, but it will get me another few miles.

Cool seafoam where do I put it

I have a 95 d90 and I want to run some seafoam through it. It says to pour some in the throttle body, how do I get to it. I don't know where it is. It also says to pour some in the crankcase. Do I just pour it where the oil goes? As you can see I am far from a mechanic. Any help would be great.
thanks, Jon

Jon, The way I read the instructions, since it's petroleum based, you can add to both the oil and to the fuel (either in the tank or into the throttle body). I removed the vacuum line from the brake master cylinder. Give it a little tug and it will pull out. No need to take off the clamp to remove the hose, just pull the plastic fitting out of the rubber grommet on the master cylinder. There's suction on that line. Put that line at the top of the can and, with the motor running, the Sea Foam will be sucked into the manifold. Careful not to stick it too far into the sea foam, or it'll flood the engine and the motor will die. I put 1/3 of the can into the throttle and the remainder into the fuel tank.

No one in their right mind would pay me to be a mechanic either, and if for some reason you trust me and the guys here say I was wrong... well, we're both hosed.

Ken,
Thanks It worked. I did flood the engine but after I got it started it ran great.
Thanks again,
Jon

Merging the 2 Seafoam threads and moving it to Tech as its a good little tidbit.

John it does say to poor some in the crank case, but it also says to do an oil change within an hour of running after pooring it in.

Hi Mike,

I poured some into the crank case on Saturday to free a sticky lifter, I didn't read anywhere on the can or the web site that they recommend changing the oil after an hour? Where did you see this?

http://www.seafoamsales.com/motorTuneUpTechGas.htm

I went from Dino to synthetic and now have a sticky lifter, so far the Seafoam has not fixed it but I only ran it for about 10 minutes after using it in the crank case.

Zed

PS. I also had steam come from the PS of my engine

Hmmm, I'll have to check the can I thought I saw that on it.

Well I got the seafoam in the system. I changed the oil, but it was a day after I put the seafoam in. What a mess I made. You know I read the owners manuel and it does say to put the new oil in before you take the filter off. I could not undersand how you could do that without all the new oil spilling out. I just did it the regular way took the plug out then took the filter off then put the oil in. I realized after I made a mistake. But luckily the oil light did not come on and no wierd noises. I suck at doing these kind of things.
