    Transmission grinds going into L or R

    1984 Chevy K30. 454. NP435. NP205. 33k on the clock. It has definitely turned over at least once. I have put about 8k on the truck since I purchased it in 2019. Recently, my transmission has been grinding when I shift to Low/1st or Reverse. I adjusted the clutch (mechanical linkage) and the...

    049 Heads

    1984 RCLB Chevy K30, 454, SM465, NP205, D60, 14FF w/4.10 gears I found a pair of complete 049 heads locally for $175. From what I’ve read, they’re a desirable head for daily driver/towing applications. Depending on what I find (2 vs 4 bolt mains, stock bore vs .030, 0.060) when the 454 in my...

    14 bolt FF hub seal orientation

    I’m in the process of installing new brake shoes, drums and hardware and inner and outer wheel bearings and seals in my 84 K30. The rear axle is a 14 bolt full floater. I took pictures during disassembly but am now second guessing whether I may have installed the passenger side seal backwards...

    Brake pedal needs manually reset after depressing

    Hello, I recently changed out a leaking hydroboost unit in my 84 K30. After doing so, I noticed that the brakes seemed to remain engaged after releasing the pedal. After driving the truck a while, I discovered that the brake pedal is not fully returning to the "up" position after being...

    Edelbrock 1406 Fuel leak

    When I went to start my pickup today to keep the battery charged and seals lubed (been stored in the garage since late November due to our crappy winters and an abundance of road salt used in PA) fuel began gushing out of both of the ports near where the step up piston is located. Any ideas what...

    81-87 bench seat wanted

    Looking for a 81-87 bench seat in good condition. Prefer black but would consider other colors. I've priced out the cost of redoing the factory seat at approximately $800 so I would not be interested if you're asking more than that. I would prefer to pickup (I live near Pittsburgh...

    Steering shaft...leak?

    I recently developed a leak (another one) that I have been unable to track down the source of. If left parked, the driver's side frame rail near the transmission crossmember starts to bead up with what I believe to be power steering fluid. I have a hydroboost truck. It makes no sense to me...

    Idle speed continues to climb

    I’ve been messing with the high idle speed on my K30 for a few days now that it’s getting cooler out. Engine is a 454 and factory carb has been replaced with a Edelbrock 1406. A while back, Craig85 provides me with the correct idle speeds for my configuration: 700 and 1900 (high) It seems...

    Help diagnosing power steering squeal

    My truck is equipped with hydroboost. My power steering pump periodically howls like a banshee ever since I replaced my V-belt. My truck also has factory AC which has been bypassed via shorter V belt since before I purchased it. I elected to replace the belt (due to its unknown age) with the...

    High beam, 4x4 and low range indicator lights

    As my handle would indicate, I have a 1984 Chevy K30 with the Scottsdale trim package. Truck is a factory big block with a 4 speed. Transfer case is a NP205. When I purchased truck approximately 1 year ago, the gauge cluster was half operational. I have corrected several issues by replacing...

    Ammeter/voltmeter gauge suddenly quit

    As the title states, my ammeter/voltmeter gauge decided that it did not want to function anymore. A quick search on the google box seemed to suggest that this gauge obtains its reading via the printed circuit on the back of the gauge panel...is this correct? Or is there a sensor somewhere that...

    Harmonic balancer removal issues

    Decided to replace my separating balancer today since I finally have the time to do so. Bought an OEM tools brand puller to help me complete the job. The puller came with 3 bolts I needed, a "ducks foot" and the pressure pin which is tightened to pull the balancer. After several rotations of...

    Timing woes

    My truck, a 1984 K30 with a 454 and 4 speed manual, runs fine. The plugs I just changed we’re all a very light tan color. However, since I can never leave well enough alone, I decided to check and adjust (if necessary) the baseline and total timing. A member, Craig85 I believe is his screen...

    Cooling system capacity significantly less than manual states

    Decided to service my cooling system today. First, I ran an off-the-shelf "cleaner" in the system for about 100 miles before draining the system via the lower radiator hose. Also, I ran about 5 gallons of water through the engine until the fluid exiting the block appeared clear. I removed the...

    Please help me identify this solenoid!

    Today, while loosening the thermostat housing/waterneck to change my thermostat, I broke the plastic piece (pictured below) on the solenoid pictured below. Attempts to identify the part have helped me narrow it down to 2 possibilities: one it is a TCS solenoid used to regulate vacuum, or two it...

    SM465 linkage question

    Today I replaced all 4 shocks on my pickup. While changing the drivers side front shock, I disconnected what I believe is the clutch fork spring to allow for a greater range of motion when tightening/loosening the upper shock mount bolt. I reconnected the spring when I was finished. After...

    Bilstein 4600s on a K30

    It looks as though these shocks are recommended for K20s on various sites...summit, rockauto etc. but not for K30s. Is anyone running these on 1 ton 4x4? I put a set on my 96 F350 and it really smoothed out the ride. Truck is stock height. Thanks, Eric

    NP205 question (pics included)

    Decided to finally fix the transfer case tailhousing leak on my K30 today. Upon removing the housing itself, 3 pieces of what appears to be a snap ring fell to the ground. While trying to figure out where it came from, I noticed that there seems to be some front-to-back play when I push/pull on...

    Do I have a limited slip differential?

    Opened up the rear axle today for a fluid change and to confirm my axle ratio. Ring gear has 41 teeth & the pinion gear has 10. This matches my RPO codes on the sticker under the hood. My RPO codes also indicate that I have a locking differential but I don’t see the usual spring etc. that are in...

    ignition and carburetor tune up

    I am planning on replacing the ignition control module, rotor, cap, coil, wires and plugs on my K30 this coming Sunday. I would like to verify, and adjust the timing, if necessary. The truck runs as it sits but I would like to replace them since have no idea when any of these components were...

    Surging idle in cooler temps

    Over the past month, my K30 has become ornery when the temperature is under 50. It fires right up but the high idle from being choked doesn't seem to shut off for quite some time. This can be remedied by "stabbing" the throttle which brings the idle down to a normal speed. If I do not do...

    2 or 4 bolt mains

    Does anyone know if any 454 powered (factory) C/K 30 trucks came off the assembly line with 4 mains? My 84's fender "tag" says it came with a 454; that is what I'm told is in the engine bay now. Obviously, I have no idea whether the engine is the original without checking the casting numbers...

    33x12.5 on K30 without lift

    I’m in the market for some new tires. Ideally, I’d like to go with 33x12.5s. Probably going to go up to a 17x9 wheel since I plan to do a rear disc brake conversion in the future. Has/does know if these will fit without rubbing on a stock height K30? Also, has anyone run rear discs on anything...

    Electrical gremlins, are they related?

    My, dash lights, cabin lights and tailgate marker lights do not work properly. When I turn my lights on, the fuel gauge goes to empty and both my oil pressure and temp gauges max out. I may be mistaken but I believe I read that these ^ may all but on the same circuit.. can anyone confirm this...
