Car was choking/bucking above 3000 RPM. Pending code P0524, engine oil pressure too low. Bucking was due to limp-home mode. This happened twice before, and clearing the code fixed the problem. Dealer verified faulty oil seal on rear valve timing cover, causing internal oil leakage and low oil pressure to the valve timing controllers. Seals not sold separately, so you have to replace the whole rear timing cover. Either way, a very labor-intensive job. Car was out of warranty but had very low miles, so I asked the service advisor if Nissan would pay for part of it. He checked, and they agreed to pay 20%. While dealer was replacing faulty oil seals on rear timing cover, they found evidence of coolant leakage from the coolant pump. Replaced coolant pump.
