See these

are a labour of love, a mistress and an expensive hobby. Diesel engines like these are known to last but the bean counter DCJ engineering, the EGR and known fail points of these jeeps make it dicey. for any older jeep with history unknown here is the list of things that need to be done
1 timing kit $ 400
ARP head bolts 350
Weeks Kit 1 & 2 300
Rockers 375
thermostat 200
Glow plug 100
new turbo 1200
Torque converter 600
now optional stuff is GDE tune 600 fuel filter head $$ ? samco hoses 250 radiator hoses 150
and if you are like me you have to pay a lot of man hours at

pirces then you have some what reliable machine.
I do not want to come off as harsh, so please bear with me. Why are you saying all this has to be replaced as soon as he gets it? I strongly disagree.
☼Don't drive like a maniac. This is a Diesel, not a gasser. If you want to hit 3,000+ revs a lot, then don't buy a diesel.
☼Yes, get a timing belt change, ABSOLUTELY. And yes, they are a reasonable do-it-yourself job if you have anough mechanical apitude to tell which end of the wrench to use. I am on my original water pump, having opted to not replace it. I will do it, however, at 200K miles.
☼If there is not a leaking head gasket, why replace the head bolts? -$350 I have 163K miles, and have no head gasket leak.
☼If you get the GDE ECO tune (the HOT tune is too aggressive IMO, and causes issues, like head gasket leaks), so the Weeks kit is unnecessary: -$300
☼Rockers? How about waiting until they fail? Again, 163K miles, and mine runs like a Swiss watch (knock on wood). -$375
☼Why in the name of whatever deity you like, would you replace a turbo that is working fine? -$1,200
☼The T-stats fail, but getting a full replacement is completely unnecessary. For $60, you can get an in-line T-stat, and it solves all the issues. (Hint: Yes, I did this).
http://www.amazon.com/Meziere-WN0072-In ... thermostat☼Glow plugs: Yes, some folks have problems with them. I've not. YMMV
☼ECO tune is your best bet. With that, you shut your EGR off 95+% of the time (maybe as much as 99%, but I do not recall).
☼Torque Converter? Well, if you make the mistake (again, IMO) of getting the HOT tune, yes, replace the TQ converter. You're gonna blow the factory one apart, anyway. If you go for the ECO tune (I did), you should be fine. I have been. And I also do towing.
I have the ECO tune, and that thing was a deity-damn blessing. I installed it at 84K miles. I also have the GDE Transmission tune (F37 delete). The only time I get any shudder is when accelerating from the low-50-mph range *just* hard enough to not downshift. It dissipates by 60 mph.
I love the GDE products.
163,xxx miles (some of that while towing 5,000 lb boat):
GDE ECO Tune
GDE Trans Tune
Rotella T6
Original Turbo
Original rockers
Original head gasket/bolts
Factory defunct T-stat with an in-line T-stat replacement
Original TQ converter
Original glow plugs
No Weeks kit
I will note, however, that if you are concerned about the rockers, then replacing them during a timing belt job is ideal. When you get the cams locked in place, you're only adding 6-8 hours to the job anyway, depending on your level of mechanical aptitude. If you are going to replace the head bolts and gasket, this is also the time to do it, but understand that this does add a lot of time to the job. If you do all this, understand that this is going to take you a full weekend, starting on Friday evening. I just did one of these jobs a bit over a month ago for another LOST member, so the phrase "in my experience" is applicable.
