The warranty isnt the point, the point is to many people put up with crap and give up while companies like NISSAN and dealerships keep making money from something that was ment to be rectified.
Looking into the legal side of it I was assured by the service manager the later motor that I installed was changed in design and are more reliable then the early models, so the first one lasted 180000km with the wrong type of oil being used and this one lasted 60000km with the right oil so Ive got a case if it comes to it.
Bad publicity goes along way,
A old girlfriend once told me the squeeky wheel always gets the grease so Im going to start chirping!!! and I think sleeping around helped her two.
