I just changed my spark plugs a couple weeks ago, after using the Seafoam will they need to be changed again? I did a search and it seems like there are some mixed opinions.
Also, I noticed that most people say to change the oil 100 miles after using the Seafoam but would it be okay to change the oil immediately afterwards instead of waiting 100 miles?

i'd like to know as i'm in the same situation...also i've always heard change oil after the car stops smoking...prolly 5-10 miles

I wouldn't wait 100 miles. I changed mine within 20 miles. This is assuming you put it into the oil. There are different uses for it. One is to put it in the oil, the other is to suck it in through a vacuum line and into the top end. If you put it into oil it won't affect plugs, if you put it through vacuum line it won't get into oil. (idealy anyway, lol) Of course, you can always do both.

advantages to each?

blkZ28spt

They each do their own thing. On a 98 that apparently hasn't had it done in awhile, if at all, I'd just go ahead and do both. Cleaning the top end via a vacuum intake seems to be the most common method. Supposed to help burn off carbon depsits and the like. Using it in the oil is supposed to get sludge and crap out. it messes with the viscocity of the oil though, I think, so I wouldn't drive it hard or far/long with seafoam in the oil.

oh i see...well i suppose having 101,000 miles on mine and it never has had it happen i should do it huh...haha...i need two cans? one for the pcv and one for the oil?...i have one can already just wondering if i need to get another...i'll prolly end up just doing the pcv hose and leave it at that...

One can might be enough. Read the label. You should only suck maybe 1/3 of the can into the top end, then you can just poor the rest into the oil.

alright will do...thanks

blkZ28spt

I don't think it's necessary, but it's certianly not a bad idea. I would, even though you just did. It's good practice and hopefully doesn't take too long. I did mine in 1.5 hours last time and it could have been a lot quicker.

can you just wait to see if they go bad afterwards? i'd rather not go through all of the work when it is not necassary

blkZ28spt

How will you know if you plugs go bad? Or have reduced performance or a shorter life....?

when it starts running rough...couldn't i just pull a couple of them and check them to see if they look alright...or is there no way to know

blkZ28spt

Yes, pulling a couple of them. I'd worry that it is reduced but not enough to notice. If you are going to worry about it, that is. I suppose it is very easy to pull the #1 and #3 plugs. That wouldnt be a bad way of doing it.

okk...well that is what i had originally planned...i'm not really sure what a bad spark plug looks like...other than the ones i had that were completly black from running so rich..haha...i'll post up something later on when it is all said and done...

Okay, I just Seafoamed my car and I'm getting ready to change the oil now. After using the Seafoam I noticed a ticking noise at WOT that sounded like it was coming from the drivers side. It mostly went away but I can still hear a faint ticking when I really get on it. Is that normal?

Don't drive your car hard w/ sea foam in it. On another post somebody asked this same question, and I believe its because the lifters are clean and they start 'ticking'. Change your oil, it should go away.
