From my understanding the old 2L's and 2LT's have a tendency to crack heads. The one thing I learned from a few people on here about the 2LT's, is that they are not a powerhouse, but they are a gas mileage getter. As Marlin told me, it will get you there, and wheel the trails, and get you back on 30 miles per gallon.
Here is a link to the making of the Willy Mammoth. Around page # 60 or so, they start discussing about going with a 1KT-Z turbo diesel.
So, line up some oil cans, cause that post is worth reading from beginning to end!!
