if you read my other posts through out this forum i have said exactly the same thing as what you are saying.
I dont believe all the hype that people say 100% of yd25 engines will fail and i have had lengthy debates with members who have tried to suggest such a thing.
As for the arm chair warrior comment you have absolutely have no idea of my background in the automotive industry so your comments in that respect are void, my point is that if you have a read of all the people that have had actual failures and that have had "the people in the know" fix that issue then you would see not only pictures of what failed but their reports from said people about what actually failed.
Further more if you read my post in reply to yours and didnt just get on your high horse you would of read that this so called arm chair warrior has had first hand experience with a timing chain being replaced by nissan, after nissan hq wrongly diagnosed the problem my 2010 st was having at which time a had lengthy discussions with allot of "people in the know" and all of those people agreed with my original comments.
The thing that i do find hilarious about your "arm chair warrior" statement is that you your self said that is exactly how you have gathered all you so called "facts" after all look at your phone bill, lol so instead of getting a well rounded view from all aspects and resources available to you so you can build even a general consensus, your ring a few nissan dealers and a so called mechanic or two and come up with all these "facts" what is a well known fact is that any manufacturer will blame everyone and everything else other then their own product for as long as possible to minimise warranty claim and avoid recalls, how many times have we heard of a common problems only to go to the dealer and hear "its the firsty time thats ever happened" or "we have never even heard of it before" that is why so many people end up in court fighting against the manufacturer they deny deny deny right to the very end.
So apart of your super thorough research is also a little lacking and was in know doubt a waste of your hard earned in having to pay the "phone bill" you winged about
you even go on to say that you have no proof, what i have spoken about i can verify im not taking a stab in the dark its all from people in the know who have either worked on the cars to fix this issue or from people who have had (like me) a first hand experience from their own vehicles.
When you can produce evidence that all the failures are due to the sprockets and not the tensioners or the chain stretching i will be on your side.
When you can show me that paul from yd25.com is a jerk and is ripping people off and his product is crap i will also like you steer others away
when you can prove that the double row chain causes more problems like yu suggest then again i will eat my words.
The trouble is you cant do any of those things and thats why you have decided to turn the atack onto me simply because i said that to pull an engine apart and only change a sprocket but not he chain and guides while you have just taken the time and or money is a dumb move.
Just like we do about you now
