We have a 94 fj80 with 205k miles on it. took it on a 3 hour trip this weekend and when leaving just as it started up there was a weird grinding noise. i think it was just my dad holding the ingnition to long but i popped the hood and when he gave it gas in neutral there was a strange sucking type noise coming from somewhere close the the air intake...i dont know for sure. but the weirdest thing is once we got going there was white smoke eveywhere for about 3 min and then it cleared and drove home fine. oil pressure was great. good temp...seemed fine but it was kinda scary...what could be wrong....and any opinions on the new 4runners. thanks
