Hi, I have the low oil pressure problem on my VQ35DE rev up. Anyone changed these ? I have replacements but cannot work out from the Haynes or factory manual if i really have to take off the cam chain. Anyone know if you can get the two plates off without removing the chain? Just planning the work, it looks a big job. Also I went for Permaseal ones from Performance Z, but I wonder if i should have gone with the metal cored ones, anyone had experience of either ?
