The one I sold out of mine was 625 with a dyno to prove it. Around here you get more for the motors than the whole trucks

 

it runs fine. Just leaks everything fluid wise. Thinking of taking the motor out and doing a complete overhaul on it.

 

Probably not a bad idea. At least reseal everything.

 

The engine is probably is decent shape, I had a 02 with 452000 miles on it and all six cylinders had over 430 psi of compression. You need a special injector/insert to do the compression test. It will looks like an injector. 5.9 heads are prone to cracking. You could run a 5.9 CR head if you wanted, they seem to take the heat better (you just have to modify the injector cross tubes/edge filter). The VP injection pump then to get weak over time. Some people swap to the P7100 pump. If you do a full rebuild, install a 12v camshaft (it has a lift pump lobe) and you can run a VE lift pump instead of the stock electric piece of crap.

I would check the turbine housing for cracks on the 66 silver bullet, seen a few cracked over the years. You probably have front/rear main seal leakage. There is a side tappet cover that's also prone to leak.

 

if the motor and heads are in great shape I plan to spend the money to convert the fuel to the p7100 for sure. The extra $1100-$1500 sounds like the way to go to avoid a tow truck. On the transmission part would ATS be the way to go? I plan to tow a lot. Don’t want a drag truck. Just looking to build a truck that will run 500k+ miles with less troubles.
mom very much interested and anxious to see what is leaking and what is good.

 

Most Light duty diesel engines need rebuilt by the 300,000-500,000 mark

 

You can get the injector lines for the P7100 from pure diesel or schieds. A 13mm pump would wake up the 5.9L with 4k gov springs. You will need a 12v gearbox housing/12v injection pump (an adjustable timing gear would be the ticket). Curious if those 275 injectors are using the 275 marine nozzles (7 seven hole). I ran a set of 7x12's at 300 bar, they worked pretty decently on my 02 VP engine. I would lower the pop pressure some if you go with P7100 pump. The cheapest way is to buy a 12v and go that route and sell the 24v as is. There are tons of threads on how to do the conversion. Probably the worst thing to fix the tach pick-up as the 02 VP truck run that pick-up under the VP pump. You could even build-up a 6.7 for the girl and run some real sized turbos like T4 s467 over T-6 s510's, probably a daily 1200 rwhp set-up. The S467 works good on CR 6.7's as a single, a buddy of mine runs a custom S478 that I built for his 12 ctd dodge.

I'm not a fan of ATS (their ok, but way over priced for what it is), I've broke or had friend that break them just like everyone else's transmissions. Just get your 47 upgraded with 48 bits, you probably do the build yourself and save a few bucks.

Keep us post on what you do. Best of luck.

 

You don't need to P pump it unless you wan't more power. The VP44 injection pumps are reliable as long as you keep a good fuel supply to it which is what that Airdog 150 is doing, add a fuel pressure gauge if you haven't already and don't let it drop below 10-12 psi. Don't get an ATS Transmission either, Look at Revmax, Goerend, or Firepunk Diesel. Also if you tow a lot get rid of that 66 mm turbo and either drop down to a 62-63mm single. Or go with a 62 and 75mm compound turbo setup.

 

So today I started to get into the project. Have a few new tools to take the motor apart as I plan to rebuild it. Before I do I want to do a compression test and leak down test. I have the injectors out but I’m having an issue. Either I have the wrong compression test kit or I’m just too stupid to figure out how to get the test port into position to preform the test.

 

Compression tester generally just screws in to the spark plug hole.....
