yea there was a recall for head gaskets. you can look up your 4runner on the toyota website to see if it's been fixed or not. if not they'll do it for free.
I Just replaced mine on my 93 and i bought it for 100 from a radiator shop. i put it in myself and have had no problems so far. i just dont trust the internet with some things haha.
mine had a very tiny leak. nothing like smoke coming out or anything. i used the sealer and it worked for me. idk about you though, it seems a little worse than mine haha
just bought this 93 sr5 about a month ago for 1500. i am in love with it :D
