Just replaced original timing belt at 145k miles! Ooops!

I feel like I came incredibly close to losing my car (well, the engine at least)..

A couple weeks ago, I took my '91 into Autowave for its second timing belt service. I was going to wait a few more months (until my next oil-change) before doing it, but since I was leaving for a week, I decided to get it taken care of so I wouldn't have to give up my daily driver later. The car has about 145k miles on it.

While paying for the service, Shane told me he was very glad that we took care of it sooner rather than later - that the water-pump had been previously replaced, but the timing belt looked like it was the original! And it was starting to come apart! I was shocked, realizing immediately what sort of damage I was risking all this time!

It was my understanding that the timing belt had already been replaced according to schedule. During the car's PPI at Autowave when I bought the car, we called Acura of Sacramento, who had serviced the car prior. Among other repairs, they said the car had its timing belt done at 74k, and had the 75k and 90k mile scheduled services.

Autowave is very reputable and knowledgable, so I'm inclined to believe that the timing belt was the original. The possible explanations for this scenario that I can think of are:

- The installer who was supposed to replace the timing belt didn't do so, possibly pocketing the part?

-There's some issue with my car that caused the timing belt to prematurely age and wear, causing it to look like it was the original?

-Acura of Sacramento told me bad information (mistakenly or otherwise)? The other information they gave regarding the car seemed to match up with the vehicle, but I suppose it's possible that they were reading service records for some other car..

Anyway, I suppose the lesson here is to hold in high esteem hard-copies of service records - since if I had those, I could more solidly determine what was going on. I don't think the timing belt is usually one of the items checked during a PPI due to the difficulty of checking it. So it would seem like you just have to trust your information. With the consequences of failure being death of your car, perhaps it is worth adding this one to the checklist? I feel like I got lucky - I'm very fortunate to still have a car to drive around!

It may be impressive that the timing belt lasted twice the recommended replacement interval. But clearly the belt isnt designed to break after 72 months, since it must last at a minimum 72. Timing belt longevity is not something we need to figure out, just get it replaced! This is not an experiment worth repeating!

I wish I was as lucky as you. My DD CRX snapped the timing belt (while driving) that was only 7 years old with less than 75000 miles. Me not real happy right now!

Bent valves are not a pretty sight (for the wallet as well) :mad:
 
Better late then never...Luckily everything worked out or we might be reading a thread with a different title.
 
I had mine replaced at 46K miles but considering the age of the car 1991 model I had it changed few months after I bought it 4 year ago. Better be safe than sorry.
 
Maybe it really was the second belt. I had mine done at about 75K miles, but the belt looked like it was about to break. Could the belt actually last 145K--how would we know?

changed mine at 60K (12 yrs) and it still looks very good.

My '94 NSX had the timing belt done at about 85,000 miles and it still looked great!! My '91 NSX had it done around 90,000 miles and looked equally good.
 
Remember to always ASK FOR THE OLD PARTS. You can always dump them after you've inspected that they have changed everything you asked them to do. I'm just glad that all went well for you and now you can track future maintenance more rigorously.
 
I'm so paranoid that even though I have a record showing that the dealership where I bought my NSX replaced the belt two years ago, I pulled the valve covers off last weekend just to be sure for myself (and to check the valve clearances).

Turns out the belt was new after all. :biggrin:

Why would it be designed to break after 72mos and why must it last a minimum of the same time frame.
Since the vast majority of our cars are driven as often as others it would be pretty difficult for Honda to design the belt to break @ 72k or the time frame recommended for change. How would the belt know when to break?? :rolleyes: :confused:
Also, just because you buy a new belt it isn't required to last that long either. All FMC parts are given a 12mo/12k mile warranty which covers parts and labor if installed at a authorized FMC repair shop. Honda has the same warranty. I'd like to see you go to Acura 4yrs down the road and tell them you want them to pay for your engine damage since the belt they sold you broke.
Either way, you are fortunate that it didn't break.
Can't put a price on peace of mind not having to worry about it now. :smile:
 
this wasn't on my nsx but i just recently had the timing belt replaced on my 95 honda passport with 172K miles and the mechanic told me that it was the original t-belt. He couldn't believe it lasted that long.

That is awesome! I don't think I have to worry about any of my Honda products for a while since one is brand new, one is about yr old and the other 2 are about 2yrs old. :biggrin:
