I had to replace the rods and pistons, since the hammerhead before me let the rod exit out of the oil pan... bent 2 others and busted a piece out of the girdle. One of the injectors was also flowed at 170 while the rest were at 340, so it must have gotten REAL lean, and blown up. That's why I went in an replaced it all.... didn't wanna spend $2500 on stock NISSAN junk, so I bought good rods and pistons for $1000. Made sense to me. Hope to paint it now...damn it's ugly! Did you see the other pics on the site? It's screaming for some paint!
