My 1992 sc400 has about 192k miles, never been seafoamed, ive really been wanting to do it cause i know the engine must be filled with ickyness, just wondering if its safe, was going to do 1/3 in oil, 1/3 in brake booster, 1/3 in gas, should i put in crappy spark plugs while i do it? and i need to change the oil immediately after correct? My father was skeptical of me doing it so i needed to show him proof it would be good for the engine, thanks.

If your current spark plugs are relatively new then yes put some cheap ones in while you seafoam it. I did the exact thing you are going to do and it turned out great.1/3 in oil, 1/3 in brake booster, 1/3 in gas. Make sure you sip the seafoam very slowly into the brake booster, small controlled sips to avoid stalling. I had my dad keep his foot lightly on the gas ~1k rpm. After it smokes drive it around for a bit at high rpm, then go get your oil changed and swap spark plugs. Hope this clears some stuff up

I sea foamed my old 240sx, I guess it pulled up some old carbon and started an oil leak.
