Just bought a Nissan... Its an early DE @ '93. I haven't found any UOA posted, or anybody discussing these motors, specifically in an early Altima or 240 since they were also used as truck motors w/ some internal changes later on. All ran off timing chains though AFAIK. Are they particularly hard, or easy on oil? Known to be oil burners? I haven't put enough miles on this one to know yet. The filter is a horizontal style... Are there any filters besides the Wix/Pure One/Napa Gold (Identical to the Wix, right?) that have silicon anti-drainbacks for this app? Is the silicon adbv a big plus, or really necessary? Thanks BITOGers!
