Thanks Pesca, when did the QR go to the "second generation"? that is basically is my question. In 02 to about end of 03 on the QRs Nissan allowed Americanized bearings in the QRs, along with cat remapping nightmares and loose intake screw etc.
Back in 05 when I bought my QR25 Xtrial I then believed that 04+ Japanese built QR engines had corrected these issues. I then learned that they did NOT after I bought the piece of [censored] in 05. I learned the bull [censored] is still going on with intake screws on my 05 QR25 and the same cat issues, I understand Nissan put on some washers on the intakes screws that still fail miserably in design flaws. I also now learn that lock tighting the intake screws is a short term fix and should be redone every 70k kms as a maintenance item. That is 3 hours in service bays on labor at $110.00 per hour at MY expense to deal with Nissans failure.
QR25DEs in Japanese made QRs post 2004 to "whenever?" are still suddenly consuming oil and losing power due to intake screws coming loose and destroying engines, I also hear the cat converters are destroying with pieces of cat going into engines and killing the engines. SOME do get engines replaced, MOST do NOT, it is a lottery that will generally render LOSS. Nissan Canada is NOT the same corporate citizen Toyota now shows.
My X-trail has 1 month warrantee left, no such trauma has happened, nor will it because I dont do high revs or nasty bumpy driving which I understand increases the chance of intake screws coming loose, that does not mean they wont some day and if it happens my engine is toast without warning instantly over someting so simple and minute as intake screw fastening. So, I guess I cant drive my Nissan with revs or use this "rugged" AWD over bumps, I have to slow down on the #1 Highway over railway tracks or risk destroying my engine. I actually do slow down over smallest of bumps to prevent my QR from having intake screws fall into my engine and destroy it, I do this because I know Nissan is not going to stand behind this X-trail on or off warrantee.
Customers like myself in 05 believed that Nissan engineers within a 4 year period would have these simplistic problem of 8 intake screws being fastened properly, this is not rocket science.
Toyota halts all factory and sales operations over a simple gas pedal issue VOLUNTARILY, Nissan will not over intake screws killing engines, instead they repeat the exact same mistakes for YEARS KNOWINGLY. I believe any certified mechanic could come up with a permanent solution quickly and effectively. I have 0 faith left in a company who in pure neglegence will continue to push out QR engines for years with a petty issue of a few intake screws not address to prevent engine destruction.
I have other shamefull examples of Nissan, google " X-trail brakes" and read those nightmares of Nissan design failings and NO responsiblity on Nissan behalf for one example.
So how long did it take Nissan to address petty intake screw issues, how many YEARS of engineering did it take, when did the second QR generation start? It is like the old joke, how many men and days did it take to change a light bulb?
My comments are against Nissan Pesca, not you.

You cannot go wrong doing that.
