i had a 94 4 runner sr5 3.0 with the auto for 12 yrs  . during that time damn near every 35k miles the head gaskets were replaced . after the 3rd time toyota said enough and  next time it was on my dime like i did something wrong .

 so i took the heads  off to the machine shop and were redecked flat and i used ARP studs . now that i picked up a bit of compression back my mileage picked up and ran much better for about 3 years and then the tranny started acting up . this time the head gaskets lasted 80k but i had enough spending money on the motor .

 my tacoma 2.7 has more power better mpg ..

the 3.slow has all the power of a 4cyl and the economy of a v-8 ..
