IMHO it would be a shame to dismantle an otherwise good truck for parts. I understand that the joy of ownership is somewhat tainted right now. Even if you do not want to mess with that engine anymore (for example, because after this, you just would not trust it anymore), consider pulling the engine and parting the engine out. A known good IP is a few hundred bucks, starter, turbo, alternator, heads all have a price. Rest is scrap (and it weighs quite a bit).
Use the money towards a re-power. Same LDT if you go budget. LDS for a bit more power (keep bell housing and oil pan from the old engine...read the conversion threads). Fix the clutch while the engine is out (you would have had to pull the tranny anyway). You can get a "known" good engine from trustworthy individuals on this site for reasonable money.
