:banghead: :uhoh: :frown: :frown: :frown: OK i have a 1990 sr5 v6 4runner. it has about 209,000 miles on it. juts the other day i got a k&n air filter for it. and fuel injector cleaner. i put the injector cleaner in with only 1/2 of tank of gas. and the next day when i left work. my 4runner started to bog out on me and a insane amount of white smoke. weird smell too. so i drove it around tonight for about 1 hour trying to burn off some gas. after filling up thinking it would help delute it. but nothing. just as bad. and resivore boiling too now? please help this is my daily driver. my only way to work. i need to find out if this will go away if it was caused by the injector cleaner? or the K&N filter is doing it. or if my motor is blown?? :( please help!!! thanks

Sounds like the EFI cleaner, seen it before with carb cleaner.
I'd expect it to go away, keep diluting w/gas.

TY i found out what it was, blewa head gasket. and coolant was going in to #3 piston. repairing it now. thanks!:popcorn:

Great timing.
Yeah, blown HG will make lots of white smoke too.
Had there been any hints the HG was on it's way out?

Not really one morning it started to sputer a lil. didnt tihnk anything about it. but he next day a little bit of smoke. the next day very bad bogging out and no power. coolant found its way into a piston. :( all clean now.

Wow,..that SUCKS! Sorry you had that happen to you.

If it makes you feel any better, this happened to me as well on my last ride. (Ford Exploder Sport v-6) I babied that ride. Always took care of it. ALWAYS! Turned out i cracked the head because they had been known to be a thin cast when they made the heads. Some things are completely out of your control.

Hope you had a good mechanic fix it for you and not rake you over the financial-coals.

Im repairing it myself, but im stuck. i need to figure out how to drain water out of the block. i spent over 1,500 so far. getting new heads new fuel injectrors, gasket set water pump ect. but cant go any further till i find out how. help!!

:( OK i fianly finsihed rebuilding. replaced both heads new bought just about every single thing for the top end. 1,600 so far :o trying to time it idle about 1100-1200 to high! suppost to be at 800, and also. boggs out. try to go it just wants to die.. to much air? not enough? hose plugd in wrong? i got to the point i want to blow the truck up....... please help anyone! im tired of walking to work...........

I bet you've got a vacuum leak or a hose attached to the wrong port. Could also be a leak in the intake in front of the throttle body.
