Are you still on your original timing belt, how many miles do you currently have? I am only asking those owners/driver who daily drive their evo and is still on their original timing belt that has a mileage greater than 60K miles.
Is there a rule of thumb as to how many miles we can squeezed in a timing belt compared to the recommended on the manual?
I know that timing belt is due for replacement at 60K miles maintenance. However, I am currently broke as i just spent my savings
on changing my rotors, pad and tires and other maintenance on the family van. I got 113K miles on my Van before I have the original timing belt replaced.
I think the van recommend to chnage it at 90K miles. My evo is daily drive. I just wanted to know the limit or highest mileage we can get out of
the stock timing belt (not that I am suggesting not to change your timing belt at 60K miles)...just curious..Thanks in advance to your reply...

 

I changed out my timing belt, balance shaft belt, water pump, timing belt tensioner, and other various timing belt items at 70k. I'm not too sure what the service ceiling is, but I didnt have much peace of mind driving it till I made the replacements.

I'd say if you're wanting to stretch it a bit on maintenance, at least give it a good visual inspection and look for cracks and abnormal wear.

 

Really, not all timing belts are under the same change rate-- can you afford not too change the belt is the question. A few hundred for the belt components verses the same + valves, guides and head work... let me see.......

 

At the very least I would change just the belt, and in a few months when you recoup some more cash, replace the rest of the stuff. Like posted above, if you can't afford a timing belt, you surely won't be able to afford a head rebuild.

 

@meckert...of course i will change soon, right now I am at 56K miles but if I hit 60K miles does not mean I will stop driving it. @bcrance13 thanks for the input. I know what you mean about peace of mind. Between my evo and the van, the van got the priority based on its history and mileage. So, right now the top mark is 70K .Thanks again

 

Thanks Blue91lx...I also would like to ask if there are known original timing belt failure at or below 60K miles. I am talking about failure on stock evo daily drive.

 

changed everything on mine at 59k

 

73k, original Tbelt. I have all the parts in my garage to do the maintenance - pullies, belts, water pump - just haven't gotten around to it yet.

 

Do it, or your next post will be a "build" thread.

 

I pushed it, and did my belt 3 months ago. I had 106K miles on my daily driven, lightly tuned (intake, exhaust, downpipe, cat, tune) Evo IX MR. Replaced the balance shaft belt and the timing belts with gates racing belts that I got off of E-bay.

Oh yeah, this is not bragging, this is just pure lazyness, and was lucky I got this far... I do not recomend anyone going this far.

That being said, the belts were in good condition with no fraying, and there was very little "powdered rubber" in the timing belt covers when I gook them off.

 

I am answering despite the query of over 60K users because I had already typed this all out...... see last sentence.
Inteference motors go "BOOM" when timing belts fail. All moving parts get real close and personal when a failure of the belt occurs.

I just dropped mine today at CBRD for the second belt swap and some other goodies.
To answer your query though - first done around 56K and this one in at 108K. It's more than insurance, and yes the tensioners, balance belt and pumps are all critical parts too that need replacing rather than testing longevity for sake of fate. Even if the belt holds, some other failure of an accessory component will leave you stranded and in the money hole all the same.

Good quesiton though - maybe add a pole to make for easy visible reference on this?

 

Just a side note... that yes these are interferance engines, (motors are electric) However, hydraulic tensioners rarely fail, and a bearing starts to make noise long before they go...

yes it's good practice to replace them all at the same time, as it's a pain in the *** to do the job 2xs because a bearing goes, but your engine is not going to explode if you put a good tensioner and bearing back on an engine with a new belt.

 

Change it at the regular service interval, but inspect it for any premature wear/cracks. Change it early if you have to. It's not worth it to wait, will end up costing you more if it fails!

 

I'll agree to this. replacing the timing belt, at the minimum is better than not replacing anything at all. I personally have never seen a tensioner fail. bearings yes but you'll know when its about to go due to the annoying whine.

with that said, it would suck to do that work twice or even three times to replace the water pump if it goes, or a pulley. but doing just a timing and balancer belt is better than nothing.

I don't know if the previous owner ever did the service at 60k, bought the car with 67k. I'm at 87k now, but am ordering all the parts this weekend! it scares me to go this long if it is the original belt.

 

I got the same things replaced @ 104K. The timing belt looked bad but held on.
