259,411 miles on my 92 4runner. Got it with 185xxx mi in 2007. Head gaskets done by Toyota sometime before that, again by me (my first HG job) in 2008, and again by me in 2012 (this time with Toyota gaskets). Was getting anywhere from 11-13 MPG up until my last HG job. Now I get 18 MPG from my mixed city/rural (max of 55mph) highway. Used to take this thing from Missoula, MT to Reno, NV and back about once a year. Now we have a car for that kinda travel. Wouldn't hesitate to load it up and hit the road though.

 

301 k currently head gasket changed at 271k. still running fine

 

154,000 on my '89. Bought it with 142,000 with all original timing belt components and gaskets. Replaced all of the front end stuff and still going strong!

 

1988 4 Runner 189,000 , bought ot in 2009 with 165,000

 

so judging by everyone it wont go as far as a head shop......

 

the problem is really the exhaust crossover. mine had the factory recall done around 90k. mine went out again at 271 at the number 6 cyclinder. gasket was fine everywhere elsse but there. the heat is what kills the gasket. eliminate the cross over and the fctory gasket and the head gasket issue would disppear completely in my opinion.

 

I always heard it was also improper cooling due to the passages in the head, reroute the exhaust and port the cooling pages in the head a little better you have a bullit proof motor

 

307K mi

 

Glad to hear there's still hope for my tired old engine! Here's to 307k for the rest of us!

 

I just turned 201K in my '89 4Runner. Still runs strong. No HG replacement. I just got 19mpg with a mixture of in town, highway and some backcountry 4 wheeling in the snow. I don't think thats too shabby for needing a tune up.

 

I am at 250k. My mpg is not that good. But I have been slowly doing things to make it better. 14 city 17 hey.

 

95 4runner with 256,XXX lots of weird smells bad knock and bad injector and still drive it everyday.
