How many miles on your 3.4 with out

replaceing the timing belt, been told its a non interfering engine so unless I take a road trip gona run it till it snaps.

 

I accidentally let mine go until 125K

 

why so you can get stranded in the middle of no where one night?

 

U r supposed to get it changed out every 80 to 100 thousand miles. I waited til it snapped

 

185,000miles on factory original so far bishes

 

187,554 is whats on my odo right now.. and aint changed it yet

 

i need to replace mine bad.. ha ha

 

You too huh.pressin my luck everyday

 

Do you guys loose any sleep over worrying if its going to fail? Here's some comfort, usually the water pump starts leaking before the the rubber band breaks.

Have you have to add coolant lately?

 

64k (I'll wait 'til I hit 90k on the current one though).

 

110,000 on mine.

But I plan on changing it soon, cause my water pump is leaking.

 

i just changed mine at 128k

 

That's exactly where I'm at but not by accident. I already have the timing belt & I'll slowly be getting all the other parts together. I'm not worried.

 

Ive seen one pretty badly cracked off a Tundra w/ 3.4 (~95k), but it was an older one (01 or 02)

 

about to change mine out soon (84k)

 

Do you realize that when timing belt snaps, the camshafts will STOP moving while the pistons still move up & down?? Snapping of timing belt can and most likely WILL result in bent valves in the best case scenario...

Timing belt should be changed around the 100k mile mark...

 

the 5vzfe (3.4) is a non interference engine. no damage is done to the engine if the belt snaps, but you wont be goin anywhere for awhile.


if you plan on running it til it snaps, my advice: grab a snickers, put it in the glove box

 

Do you realize that the 5vz-fe is a NON interference motor?

 

Must be due to low compression of the motor. I am not too familiar with the Toyota engines yet.

I look like an idiot, should have read the first post to the end, not just the title...LOL
