I've spent the afternoon searching and reading a few threads. My question is how much sea foam to use? I'll be putting it in spark plug holes and cranking the engine to spread it around. I won't be adding it to the oil or the gas. After I've burned it off I will change the spark plugs and change the oil.

Also, is there a point where it's harmful to the engine after soaking for too long without burning it off? Will it soaking for a week be a problem, or should I make getting the sea foam burned off more a priority than that?

I haven't read anything suggesting a long term soak will be a problem, but I'd love to hear from some people experienced with this stuff.

Before the car hybernated the winter away it had compression of 110/110/110 and 80/50-60/80. I'm unsure of the low bump cause I'm using a dial compression tester not digital. So once the needle starts bouncing I can tell it's at least one uneven bump between 50 and 60, but can't tell if I have two low bumps. From what I've read one low bump is indicative of a stuck side seal. Two low bumps shows apex seal.

If you decide to soak the engine, you need to rotate it by hand to get all that seafoam mixed. Don't just do it once, rotate it by hand for a while because the sea foam will just pool at the bottom. You're going to be loosing the seafoam out of the plug holes and the exhaust port so I'd say use an entire can, but only add 1/8th of the can at a time.

Also, any large peices of carbon that flake off can damage the engine. So rotate the engine until it seems dry in the inside and then keep rotating to make sure nothing gets stuck between the rotor and the housing. Seafoam is basically a can of kerosene, so think about getting kerosene instead and try that, as kerosene is cheaper. White gas for lanterns would work too. Good carbon solvents.

Thanks for the advice. I wasn't planning on turning the engine by hand when putting the sea foam in. I was planning on pulling the EGI fuse and repeatedly bumping the ignition. Once I had all the sea foam i was going to use I was planning to put the spark plug back in then let it all soak. Probably a good idea would be to go out every so often over the course of the soak and turning the engine some, either by hand or with the ignition.

Rotating the engine by hand to check for carbon flaking seems like sound advice. Sloshing as much fluid out of spark plug opening seems smart also. I'll do that before firing up the engine and smoking my neighbors.

Hopefully doing this will put off a rebuild till next winter. This is not the right economy to be indulging too many hobbies, buying more time would make me a happy man.

1st attempt fail!!!

I tried using a turkey baster to get the seafoam in the upper/trailing plug holes. The baster was too large so i got some old tubing from my computer's water cooling setup. Put one end in the plug hole other on the baster. Unfortunately very little of the fluid ended up in the engine.

I've got a dental syringe from having a tooth pulled. They gave it to me to clean the hole where my tooth used to be. Gonna get some more sea foam and try squirting a very little bit in at a time.

Try inserting it into the leading plugs, bigger hole.

Yeah, forgot to put that into what tomorrows attempt will be. I tried going the easy route today. I have P/S and A/C so my front plugs are a pain to get to. I have an easier time getting to the trailing than I do the leading.

How's your stuff going? Didn't we swap some PMs last year and you were looking at a rebuild also? I saw your F/S thread, too bad that Rtek your selling isn't a 1.7

well, i use one of those cheapo $5 oil cans to pump oils into the spark plug holes. the bendy hose on them is awesome.
