I started a thread here (http://www.thedieselpageforums.com/tdpforum/showthread.php?t=39469) about a problem I'm having with my truck. The problem is not resolved yet, but could very likely necessitate pulling the heads and possibly reworking them.
Here's the situation:
1. The motor has 270+ miles on it,
2. The block is damaged where one of the starter bolts screws in - this means that R&Ring the starter (or anything that requires it to be removed) is a major pain because it has to be shimmed up in order to seat correctly with the flywheel. IMO this makes the block worthless for a rebuild - unless the damage could be corrected in the process.
3. In addition to this, since it is a 94, it could be that this was one of the older blocks with design flaws (still need to check to be sure of this).
This is my work truck (mobile veterinary service) and I need it to be DEPENDABLE as I could have an emergency at anytime.
I really like the truck - I think the inside capacity is larger than the newer models and I already have the inside 'tricked' out to hold all my instruments/tools/medications/etc. All that might - or might not - fit in a newer model - without major modifications.
The power of the truck is probably more than I need (I believe it has 4.10 gears and I don't do much hauling) but it does have to haul around my gear all the time. I would like to maximize the MPG as most of my time is on the road (half highway, half back roads) but I still need 4x4, etc. I could probably gain some MPG if I raised the gear ratios, but that's a consideration for another time.
Anyway, now my question is what to do if I do have to rework the heads?
1.) R&R the heads, do nothing else and keep rolling?
2.) R&R the heads and put a short block in?
3.) Long block?
4.) Swap for a Duramax?
5.) Try and find a 93 to rebuild so that it has the old mechanical pump (reliability issue here)?
6.) 6.2?
Not sure which direction to head, but I am willing to invest and keep the truck for a good while longer so I'm keeping all my options open.
Thanks for any thoughts.
