How many miles on your 3.4L timing belt?
Just wondering what the record is. I changed the one on my '93 3L @ 100k and it was still in good shape 
Need to get it changed SOON!

Actually if the belt brakes you're just going to need a tow;the 3.4L is a non-interference engine so no damage should occur in the event the belt breaks. If I'm wrong then let me know since I think mine needs a change.

w/ the right tools, the belt can be changed in about an hour in an emergency.
when doing maintenance, the waterpump gets changed, adding about an hour to the job.

102,500 with factory belt..
I would like to change my timing belt soon...The waterpump was changed about 20,000 miles ago after it broke so I guess I don't need to change the pump when I change my timing belt

In an interference engine, the valves open far enough that if the timing was off, the piston could come into contact with the valves, and that would be plain ugly. In a non-interference engine, the valves never open far enough to hit the piston.
So... if a timing belt/chain breaks in a non-interference engine, the engine will stop, but you won't have any internal damage. If that happens in an interference engine (and especially if it happens at speed), you're in for a big BANG as the piston will slam into the open valves.

Not to hijack the original intent of this thread, but i recently bought my 4Runner in Jan. with 94k on it..is there any way to see if the timing belt was changed once before i bought it? I bought it from a Toyota dealer so is that possibly something they would check before reselling? I think i may be giving dealerships to much credit here but....Thanks in advance

mine has 3000 on it. the old one had 102,000 on it. if the belt breaks it WILL F up your engine!!!!!! the valves will get thrashed!!! so dont keep it on your car till it breaks! 
and i had a toyota guy change mine, with me, and it took him almost 3 hours with air tools , he does these things everyday, i dont get how any of you say you can do it in 1 hour !!!!

When in doubt, change it out.

I saw a Rodeo the other day with 240K miles on it. The belt looked like string cheese after a five year old tore into it. It was ugly. Don't know if they are interference.
