1. Has anyone pulled the spark plugs right after using
seamfoam? How did they look?

2. Where is the crankcase?

3. I know you dont have to, but why isn't the oil changed
after you put seafoam into the cylinders. Isn't the
seafoam being mixed with the oil?

Thanks

1. haven't seafoamed mine yet, but i haven't heard of it damaging plugs.

2. the crankcase is at the bottom of the block where the crank shaft is and it is where your oil is held. actually your oil is in your oil pan, but that is just like the bottom of the crankcase you could say.

3. when you put seafoam in your gas tank, it doesn't mix with your oil. think about it, does your gas mix with the oil?

I asked, when you put seafoam in your motor not your gas tank.

my fault, must have read it wrong. but i believe the only seafoam that gets in your oil is the half a can that you pour into your crankcase, not the half that you put in your vacuum line. what i'd do is pour the half a can in your crankcase and then pour it down your brake booster vacuum hose and run it for no more than 200 miles and then change your oil. that link that was posted is a good one to go by.

yeah i think you are a little mixed up and should read the write-up. i have heard of plugs being fouled out, but it didn't happen to me.

Who didn't change their motor oil after they put seafoam in the vacuum hose?

I pulled the plugs.. didn't have any problems so I left them in. Ran ok...

The reason you don't change the oil right after the treatment and to drive easy for 200+ (or what ever) miles is to let the Seafoam do its job of cleaning the internals of the engine. That being the oil passages, walls of the whole engine, etc..

One main job of Seafoam is to remove carbon build up, it takes some engine cycles and time to loosen the carbon and other oil build up inside the engine. Once you drain the oil, you will see that the oil is pertty dark from the loosen carbon and other dirt that was sticking to the engines internal parts and walls.

To clean the intake track and combustion chamber, you pour the 1/2 can into the intake via the PCV or Brake Booster (or if a carb.. down the carb). Pour it fast enough to flood the engines till it dies, then the intake track, combustion chamber, valves, piston and TB will soak the carbon free. Wait 20-30 min and start the smoke show !

I have to admit that it has improved the engine performance of the 5 cars that I have used it on.

I think you are VERY confused.

You do not need to change your oil when you run seafoam theu a vacuum line.

You NEED to change your oil when you put seafom in your oil. Run the car for 250 miles and then change your oil

read the link, it is very descriptive

Werd.

I use a full can once a year.
1/3 can in the gas tank.
1/3 can in the crankcase.
1/3 sucked up through the brake booster.

Put the Seafoam into the crankcase a week before a planned oil change, or however long it takes to get to 200 miles or so.
Not that this really matters, but right before changing the oil, I suck the seafoam up through the brake booster. Let it sit for an hour or so, sometimes longer. Run it hard until it stops smoking.
Change oil.
All done.
