Oh, and you also mentioned something a "sludge" problem. I haven't read anything on the various Tacoma/4Runner boards regarding any kind of a sludge build-up problem with the 3.4 or the 2.7 (4 cylinder) engines. However, I have read some posts claiming that the sludge problem was more prevalent in another type of Toyota V6 car engine. Don't know if those claims are true or not, though.
