Hmmm.. you are giving me good ideas..smj999smj wrote: ↑Sat Jan 16, 2021 6:52 pmIt does have the EGR performed through the variable cam timing, I believe, but I haven't heard of any issues with it on the V8. If you want to eliminate the issue as well as the cracked exhaust manifolds, I do believe someone was able to get the long-tube headers from Cajun B-pipes designed for the Titan/Armada to work on the V8 R51. The ECM will need to be reprogrammed by UpRev to do this.
I just got an oil change despite previous oil being fresh.silverarrow27 wrote: ↑Tue Jan 19, 2021 5:42 pmThe only thing I've come upon is that Nissan's V6 & V8 models tend to leak at the oil filter due to sludge build up from lack of oil service intervals. There's a rubber o-ring behind the oil filter housing that eventually leaks and will need to be replaced. I had to do it on mine is why I found out numerous issues about it. Just something to keep in the back of your mind if you find that there's an oil leak at the front of your vehicle.
The oil filter adapter is actually the oil cooler. The "O" ring doesn't necessarily leak because of lack of maintenance or sludge, rather, they just leak on their own. I believe the rings were updated and made a little thicker to prevent the problem in the future. It happens on a lot of Nissans, not just the Pathfinders.silverarrow27 wrote: ↑Tue Jan 19, 2021 5:42 pmThe only thing I've come upon is that Nissan's V6 & V8 models tend to leak at the oil filter due to sludge build up from lack of oil service intervals.
