Hi! As you can read here in my "new member" introduction post, http://www.nissanpathfinders.net/forum/topic/44173-wd21-from-italy/, I'm slowly restoring my '89 WD21. Some of you might like to take a look to some photos of the "work in progress", so... My engine developed a rod knock which I believe is due to debris from a broken timing chain tensioner which clogged oil passages in the crankshaft (I will check this later). Anyway, I decided to buy another motor. Z24 engines are very rare in It
