  1. 98.5-02 Powertrain
    So yesterday I installed the power driven diesel trans cooler lines kit, dumped the pan, changed the transmission filter, and upgraded the air cooler for the 47re. I then added 10 quarts to the transmission, it has a mag hytec deep pan. Then I started the truck to get things circulating and I...
  2. 89-93 Non-Powertrain
    So I had a 1991 Dodge W250 come into my possession. It's a single cab long bed with a blue and silver 2 tone. It has a 173000 miles and It's all original. I ended up selling my 2010 Jeep Wrangler JK because I didn't see the need for a gas and diesel guzzler. I'm in the military and I'm coming...

    Looking at a super clean laramie at a dealership. Has 173k on it with and auto trans and manual transfer case. Interior from photos looks mint and the exterior looks really good too. I know I'll like the truck if I can get it but it's about priced at 23k. Is that too much or just what's normal...
  4. 3rd Gen. Powertrain
    Recently did an overhaul on my 5.9 Cummins. Everything went smoothly and had no problems assembling. Before dropping the pistons in I checked each ring gap and everything was perfectly in spec. Only put brand new parts into the engine... nothing was reused. Truck started right up on its first...

    I have a 2012 6.7 Cummins. The truck Idles crazy! When I start the truck it runs fine for about 15 seconds then starts to get choppy. I replaced the FCA with the Bosch replacement (ORiellys and dodge want 3x the amount for the new brand). I also replaced the pigtail and connector as the...
  7. 98.5-02 Powertrain
    1999 Ram 3500 5.9 Cummins 24v 2WD 5 Speed So I have this knocking noise and this is my first diesel truck. I'm fairly mechanically inclined but not so much on diesel motors. I've developed this knocking noise. Sounds like it may be coming from the rear of the motor. I feel as if I can hear it...

    Just turned 16 on may 15th. Looking for my first truck, preferable a diesel one. Leaning towards 3rd and 4th gen cummins. Also would like some info on duramax. Just want to know what is my best bet whether it being cummins or duramax. If it is cummins, 3rd or 4th gen? As well as which year of...
  9. 94-98 Powertrain
    Installed a nice billet aluminum tappet cover because I was leaking out of the gasket, decided to go big or go home and buy a high quality cover. I’ve recently started running more boost and fuel. I am leaking out of the vents in the tappet cover. What would be causing this? Could I make some...

    Hey guys, I need some advice/help with a project I’m interested in. I have a 1965 Chevy k10 and I found what I think is a good deal on a 12 valve 5.9 with a Getrag 360, plus the rear end with leaf springs (I don’t want the rear end). They’re asking $3500, the drivetrain supposedly has 80k...

  13. 4th Gen Tire and wheel
    While back had a set of 16x12 Mickey Thompson class iis on a 2nd gen of mine, would love to have that look back on my 2010 4th gen. However I am aware that the smallest rim size on these trucks is a 17 due to the calipers. Has anyone gotten around this to fit 16s? I’ve considered maybe retro...
  14. 3rd Gen. Powertrain
    Last week I was going up a hill and all of a sudden, I lost all power and the truck started smoking heavily (constantly). Checked my codes and it read a “P0304” code. Changed injector #4 the other day and nothing changed... still smoked and ran rough. I have absolutely zero blow by cold and...

  18. 4th Gen Tire and wheel
    I’m looking to go to 24x12 on 35s instead on my 20x10 on 35s. I often go on dune roads and beaches during the summer and was wondering if I’m going to run into any trouble when I deflate them so there flat to run on the dune road. The area I got requires you to flatten your tires.
  19. 94-98 Non-Powertrain

    I have a 1988 chevy k3500 4x4 with the 454 big block in it. I wanted to do a 12 valve swap into it with NV4500. What are some of the issues that I have to worry about? Like oil pan clearance, new engine mounts etc.
