| #4 and #6 are commonly leaner than average cylinders, #5 and #6 seem to be the first to go from oil starvation. Why Nissan didn't put the oil pressure regulator at the END of the oil galley instead of on the oil pump is beyond me. #1 seems to die from contamination within my own reasoning? I noticed as I was adding oil last night that starting with a completely empty oil pan it took all 5 quarts to get it to the full mark on the dipstick, where normally it takes me 4. I went ahead and ordered the J&S knock guard with the gauge that notifies me when there is detonation and how much ignition retard it is doing. I also sent my injectors to be cleaned and flow tested just for peace of mind in case there is any uneven flow causing #4 to lean out. I have spun a rod bearing before at 153k original miles, when it was NA, then proceeded to drive it until it threw a rod. At the time I knew almost nothing about what would cause it but I've always been paranoid and extra cautious since. Maintaining proper oil level, high quality oil, constantly monitoring oil pressure, oil changes, ensuring the oil pan was not dented. I understood oil starvation wasn't the only thing that caused premature bearing wear so I installed a wideband and constantly monitored it as well, it seems to run on the rich side about ~11 in boost but that is only for the entire bank.
*disclaimer*: all that I say may be true or I may be completely wrong and I accept that.... please, it is your duty as another person on the internet to impolitely tell me how wrong I am :) "The dreaded 2nd windshiled wiper swipe when you turn it off its almost like tis showing you that it's boss, and it doesn't have to stop when you tell it to :("-College Boy (discussion on ptu relocation)
