The one place I have found this product to do much good is in decarboning a two cycle outboard motor. It is a mild penetrating oil. I do not think it does much of anything on a four cycle engine, except make smoke because it is in fact oil. If you think it is going to remove baked on gunk, try using it to clean an intake. It is relatively ineffective.

Okay...you should see what my 3.0 heads look like then. Oh yeah and my intake, all the way down to the valves are spotless.

Just saying...worked wonders for me. It also sprung leaks by removing all the gunk. 1993MTXSHO can vouch for the cleanliness of my heads (no ****).

This stuff is grade A awesomeness!
I ran it through my intake and fuel system, boy does it make a difference.
I've heard from many people to try it out, and it sure as **** does the job.

I don't know about putting it in my oil, I'm afraid that what ever gunk that built up in my crankcase is actually holding my engine together.

Still have to let it run completely through the fuel system, but I'm going to be traveling 60+miles tonight so it will get a good cleaning tonight.


Anyone else use Seafoam? Opinions?


You dont have a choice. Its so thin it goes right through the rings. Thats why on the can it suggests you change your oil after seafoaming.

---

There is a specific way of seafoaming. The correct way. I dont know if its been mentioned, I havent read the entire thread, but the way I do it is this...

Step one, take about a foot or more length of vacuum hose and connect one end to the vacuum tree. If you do not have a vacuum tree then disconnect a vacuum hose that leads to the intake manifold and does not effect the idle and use that. (On the volvo I used the hose that goes from the intake mani to the turbo cbv.)
Step two, rev and hold the motor at about 4k rpms, then dump the open end of the vacuum hose into the can of seafoam. when the engine attemps to stall, take the hose out. Continue this process until can is near empty, then down the engine with the last of of the
Step three, let engine sit for 15-20 minutes as the seafoam works away at the carbon buildup and gunk.
Step four, after the 15-20 minutes are up... drive the car 'spiritedly'. Let the throttle open up a few times. Drive until the tailpipe has stopped exhaling white smoke.
Step five, change your oil.

Done!

It's the universal product you can put anywhere in your engine to fix damn near anything :thumb:

The Duct tape of liquids, if you will.

I have used it on every car I have owned. It has never let me down. Well, except in the smoke department.. My current ride came into my possession with 111K on it and had never been foamed. Man, it looked like the house was on fire.

In regards to adding it to the oil. I have always done it about 200-400 miles before I change the oil. In my life that is about a week to 10 days. I am sort of tempted to leave the current filter on, put in economic dino juice, and then foam it. After which, I'd put a new filter and full syn.

It might be over **** though...

+1. Seafoam is the *******. I pour a can in my tank every few fillups and it keeps it running tip-top.

As far as the motor oil goes, transmission fluid actually does an amazing job of cleaning out your oil system if you pour a quart in a few hundred miles in before an oil change.


I've also heard and tried putting a quart of ATF in the gas tank. If I recall it has something to do with all the cleaning agents they put in ATF... Ill find the article sooner or later.




I would have put this in my previous post, however, the Edit button/link is not showing up.

I've explained those same steps plenty of times through out the thread. And I was afraid to put it in my oil because of exactly what it did (its job). It cleaned out my engine so good that it sprung leaks...which is what the manufacturer warns about when doing it to high mileage engines.

My plug wells and rear main started leaking right after I seafoamed the engine. No complains really..its just doing its job. And the inside of the heads look like they were sand blasted clean (no yellow or browns...just silver!)

Anyone ever tried diesel in the crankcase? Works about the same except the smoke is blacker. Put a quart in and run the car for 10-30 minutes then change the oil. Not sure about doing it on a car with electronic engine management though, only know of people doing it to carbed cars.
