They want me to bring t back in to check valve timing, and a few other things.. Well, I know its a load of BS, but the Dealership said Nissan techs stressed the importance of following the guidelines for break-in "strictly".. I assured them that after the first swap, I was sure to follow PAST the recommended timeframe to be sure this would not happen to me again, and here I am.
They didn't come right out and say it was MY fault, but they imply that its you and not the product.
I wonder if Nissan would do anything for me for my troubles!!!
Factory installed exhaust upgrade would be aaaiigghht......
