I’m looking at a list of timing belt/interference engines... and there are some *interesting* entries here. Not at ALL “low end”.
I can see why you might fear a simple little bet. Ah well. You have refused to provide proof for your assertion that Nissan belts fail before their 60 or 105K replacement points, I shouldn’t be surprised that you won’t take this bet.
Spktyr,
Your assertion that no Nissan belt has ever failed before its replacement interval is on its face beyond comical.
Nissan, while a fine manufacturer is not perfect, for you to claim that no belt in a Nissan ever made has failed before its mileage interval just shows flat out ignorance.
Again, You seem to keep putting words in my mouth. Whereas you are are claiming ALL when it comes to NO Nissan has ever had a timing belt fail before its recommended interval, I have clearly said MOST US cars that have interference engines and belts fall into the low end and most of those are older designs.
Why you believe Nissan can produce 100% perfection in its parts 100% of the time is beyond me. Parts fail, even great parts fail, even parts that have been inspected multiple times fail. You cannot produce 100% reliable parts 100% of the time, no one can. In case you missed the memo from the man upstairs... this world is populated with HUMAN BEINGS, and human beings are flawed, and any system developed by and run by human beings is also flawed.
All it takes for the best timing belt to fail is say, Oh I don’t know... a slight water pump leak... you ever seen what radiator fluid will do to one of those puppies? Even with if the belt had zero defects from the manufacturer its not going to last its life expectancy if exposed to anti-freeze.
I don’t know why you think Nissan is some God to the manufacturing and mechanical process, but they aren’t. Belts fail, it happens, the only thing good manufacturing and qc can do is minimize the failure rates, they cannot get rid of them. To assert that no Nissan belt has ever failed before interval is simply a ludicrous claim.
The timing belt on an inteference is the weakest part of an engine, in terms of its failure resulting in catastrophic engine failure immediately. Same is true of an interference engine with a chain, the chain is the weakest part that can lead to catastophic failure, but the chain is far stronger and more reliable than the belt.
