    All gauges are wonky...

    I'll probably find out when I get home, but is that something I can check without removing the gauge panel? Thanks!

    Roger that, thanks! I'll try pulling tonight...

    All gauges are wonky...

    Just getting my new (to me) 83 K20 moving again, and I'm needing a bit of help regarding my gauges. Here's what I have: Volt meter - Needle never moves from 0 Oil pressure - Needle never returns to 0, only moves a tiny bit (between 60-65) Temperature - Needle never returns to 0, indicated...

    Fuel Pump Woes and Questions

    Okay, so I figured it out. I'm an idiot. Looking at too many things at once, and inadvertently put blinders on. The accumulator has TWO ports. One going to the inside of the truck, and one being fed by vacuum from the intake manifold. Yep, the larger diameter vacuum line was for the...

    Rebuild Auto Hubs or Replace with Manual?

    Wanted to post an update for y'all... So, I bought some Warns hubs and everything that goes with it, and was ready to replace the autos. However when I got up here, I started tinkering with them, and they seemed to be working as advertised. Decided to put a temporary tach in and see what the...

    Header/Exhaust thoughts

    Hey folks! I appreciate all the information folks. Research continues... lol So, these exhaust manifolds have been on there, well, forever... When I do end up changing them out, what do y'all recommend to decrease my chances of snapping a bolt off in the head? I'm going to presoak with a...

    TH400 seems to be dragging

    I had to put new tires on her as soon as I started tinkering on her and decided that I wanted something with just a touch more meat on them. The stock tires were 235/85/R16 and I went with 285/65/R16. It made a nice difference, and it should have only made a few mph difference on the speedo...

    TH400 seems to be dragging

    Well, I haven't actually run her up past 60 or so, but I really notice it above 45 or so...

    TH400 seems to be dragging

    Fluid was low (that pan gasket had given up the ghost a while back), but it looked and smelled good. I changed out the filter and gasket, and other than the 'dragging', the trans is perfect. Nice, solid gear engagement, no buzzing, no slippage felt, nada... You hit it on the head though. Its...

    TH400 seems to be dragging

    Okay folks, I finally made it back to KS to give her some more TLC. :) Looks like I've got an NP208. I'll post pics showing a better view of the tag, and another shot of the transfer case itself. Now, before any rags on me, yes, I know she's filthy. lol I haven't worked on cleaning...

    Header/Exhaust thoughts

    So, I've got a pretty significant exhaust manifold leak (#2, I can feel it lol), as well as an exhaust leak at the muffler itself. Looks like it might have been drug over a stump or something similar, the mufflers bent and crooked. So....I'm thinking that if I'm going to go to the trouble of...

    TH400 seems to be dragging

    Welp, I haven't seen her yet since I started this post, but I'll be there tomorrow night. Sounds like I've got a 208! I'll double check everything when I get there and post pics. I've also ordered the Warn hubs. They should be waiting on me in Hutchinson!

    TH400 seems to be dragging

    I think I'm going to get a set of manual Warns coming, just in case. I'll also get a service kit for the autohubs. I'm prepared both ways. ;) I like the idea of manual hubs, but really like the stock look of the autos... Well, my wife does. So that means I do too I guess. lol

    TH400 seems to be dragging

    Roger that. I'll be up there tomorrow night, so I can get a better picture of the tag. I'll repost then. Quick question. I've been looking into servicing or replacing the autolocking hubs. I would bet they've never been serviced. I don't plan on a ton of 4 wheelin', but I want to make...

    Rebuild Auto Hubs or Replace with Manual?

    In my 83 K20, it feels like I'm getting some significant drag when I let off the gas at any speed above 45 mph. I've confirmed that the transfer case is not in anything other than 2H, but when I try to turn the transfer case driveshaft, it feels 'notchy'. I've double checked the brakes, and...

    TH400 seems to be dragging

    Quick update. I'm not near the truck at the moment (I'll be driving up there Friday) so I can look at the transfer case, but I'm not sure now that she's an NP205. I found this pic while I was looking for something else. Is this an NP205 or something else? Not too familiar with the tags...

    Fuel Pump Woes and Questions

    If memory serves (the truck is still in KS), the AC accumulator was hooked up. And it used a pretty small vacuum line. Maybe 1/8" ID? This line was large. Like maybe 1/4" ID. As I said, she ran a ton better when I plugged it. I'll double check it again when I get up there, just to be sure...

    Fuel Pump Woes and Questions

    'Mornin' folks! Thought I'd give an update... Dropped the LH tank Saturday morning with the main concern being a clogged pickup sock. That, my friends was a serious PIA. Should have lifted the bed, but I figured "how bad can it be???". Yeah, that was mistake number one. Not confirming that...

    TH400 seems to be dragging

    I had an '86 S-10 Blazer that I seem to recall worked like that... As an update, I put her in 4H and 4L, and it's definitely engaging in those modes. And definitely un-engaging when I pull her out of 4X4. That being said, the hubs are a different story right? I still need to pull them apart...

    TH400 seems to be dragging

    Welp, I went and tried freewheeling the short shaft. Is it supposed to free-wheel 'freely'? This one doesn't. If I rotate the shaft (in either direction), she feels clunky, and doesn't make it a full turn before stopping. This is with the engine off, and the vehicle in park. I'm guessing it...

    TH400 seems to be dragging

    Thanks for the reply! And yep, it's an NP205, and I'm indicating 2HI from the cockpit. I'll double check the short shaft for free wheel. I should have thought of that yesterday, but, well, it was a long day, and I was just excited to have the motor runnin mostly like she should! lol I'll...

    TH400 seems to be dragging

    So, I've been working on this stock 83 K20 that was driven very infrequently in the last 8-10 years. And none in the last 3 years. Got the fluids right, as she'd been leaking from....everywhere. Valve cover gaskets, trans pan, power steering, you name it. Installed new trans filter and...

    Air filter housing

    I've just come into ownership of an 83 K20. I was under the impression that it was completely stock (my late father in law owned bought the truck new, and only took it to Chevrolet for servicing). My air cleaner is of the shorter design. Gets me to thinking that maybe he didn't only take it...

    Headliner from RockAuto?

    Now that is a nifty idea! Came looking for headliner replacement options, and found another way that my much better half can get involved in my K20 build!

    Fuel Pump Woes and Questions

    I was thinking the same thing. As I mentioned, the existing mechanical fuel pump looks 'new-ish'. IE, cleaner than the other components found in the engine bay. That got me to thinking as to WHY there was an electric pump installed in the first place. With that being said, what's the best...
