Help me out here ... Does the 4HE1-TC (Duramax 4800) have injector problems as well or is the system pressure / setup different for that engine? There are a "ton" of those on the road and they seem unaffected. http://www.dieselplace.com/forum/smileys/smiley5.gif

Totally different injection system. Only similarities is that both are Isuzu's and diesels. Unless you're talking about the 4HK1.
