Looking at picking up a 94 12v cummins tomr. Body's rough. Dents, scratches, rust. Small vib a 60mph. Head liners Saginaw around the edges. Runs great.

What is something like this worth? Looking for some good solid info.

Thanks GL4x4 :thumb:

No prob. I buy them around that for a fleet I work on, we put another couple $$ in them, they make for good trucks.

Couple of things to watch, look for excessive oil in front of the motor, if there is, the dowel pin has most likely gone out. Also unbolt the turbo inlet hose and look for scoring, etc. Wobble the shaft on the turbo back and forth a bit. There should be very little play.

Lastly, make sure the tranny shifts through all gears, especially overdrive. And try to hit a couple potholes at speed during the test drive, the 4x4 versions of these trucks are known for front end issues.

I agree with all statements.

The headlight switch trends to fry as well. Valve cover gaskets tend to leak, but $20 on some nice blue felpro will get you going again. The injectors may or may not be on their way out... mine are leaky at 155k.

The overflow is likely worn out too if you notice "lower than expected" power.

More fodder for haggling.

Edit: the oe headlights are crap more than likely. They seem to take on water very easily.

thanks keith. you seamed like you have enough legit knowledge about them, enoguh for me to turn it down. interior was pretty bad, decent amount of dents and scratches, inside the bed was dented up pretty bad, looks like the front of the motor was alitte wet and had a leak at what looked like the rear main seal. thanks for all the help guys. :thumb:

The front main seal can also leak like a mofo, and just needs a "repair kit". (speedy sleeve and seal.) Unless it has some major issues, and based on what you've stated about it, I'd put it's value at 3k+. 12V's values are coming back up nowdays, and cheap ones are tough to find. Being a 94 and an auto hurts that trucks value, but still probably a fair buy at 2500-3500, IMO. I'd plan on putting some money into it either way. Just do the standard upgrades that fix the few issues these trucks have. Headlight relays, replace the seats, headlight housings, steering box brace and column bushing, front main seal, KDP tab, and a BHAF will have you set up with a nice rig.

That's why I jumped on it since I see them at 4800 on the cheap. It needed work but time is going to.be an.issue for me in may-june. I'm going to wait a couple day and and see if it sells. Then I might snag it, if he comes down on price too.
