  1. Saw this roll into a car show I’m attending today. Had to go check it out. I certainly didn’t know what it was. Who here can identify it with out help from Google?
  2. When you get to 45 MPH does it just loose power and quit pulling, or so you just feel it’s revving too high at that speed? If it is loosing power at that speed I suggest you go back to your recent tune-up and reinspect things. As Don mentioned earlier, a few of us have experienced a failure to properly connect the points spring and have experienced points bounce at higher RPM’s. When this happened for me the truck wouldn’t get over 40 and would start to bog down and run terrible. Once I discovered my error, and corrected it, I got all of my power and speed back.
  3. What you're seeing on the drain plug is actually a double square with 8 points. As stated you can use a 1/2" drive ratchet.
  4. Must have been a Wisconsin or Minnesota car.
  5. My truck has the 23" block 218 CID engine. Pretty much the same engine that Plymouth used. I don't know exactly how many miles are on it since the rebuild, but I estimate it to be close to 7000.
  6. Maybe your oil pressure gauge line sprung a leak and it wasn't the engine's fault at all.
  7. I've done a few longer road trips in my truck with sustained RPM's between 3000 and 3500 with no ill effects. I also know the condition of my engine as I built it when I restored the truck. Having a tachometer helps understand the true RPM without the fan noise leading to you believe it's spinning faster than it is. Not the greatest picture, but this was on a road trip to Detroit for a WPC meet, traveling down I-94.
  8. Maybe you need to rewire your radio to be key dependent.
  9. If you have the transmission in gear and your foot is off the clutch pedal but the car doesn't want to move when revving up the engine, then either the FD has completely failed (unlikely) or your clutch is not engaging properly (slipping)
  10. When I first got promoted from the shop into a service truck I was issued a 1985 GMC 3500 with a 454 that ran on gas or propane. It had a 70 gallon propane tank in the bed along with the stock gas tank. It didn't have as much power when running on propane, but it ran very smooth. You could really lug it down without it chugging and bucking. The downside was cold starts in the winter. If I knew it would be below freezing in the mornings I'd switch it back to gas before parking it so it would start easy in the morning. If it was too cold the propane wouldn't flow through the regulator to supply the engine with enough fuel. There were coolant hoses routed through the regulator to warm it up, so once the engine was warm you could switch it back over. Switching back and forth was a process... From gas to propane you'd switch off the fuel pump and let it run the carb dry, then activate the valve for the propane. From propane back to gas was a similar process. This one would take more time for the engine to 'catch' as the float bowl would have to refill with gas. This worked best when driving down the road so that you could use your momentum to keep the engine spinning until it had enough gas to relight the engine. Ahhh... memories...
  11. I believe you are looking at the Fluid Drive fill plug. That is a special oil that is no longer available, but it seems the closest alternative is an ISO 32 / AW 32 hydraulic oil. You should be able to find some at a local place that had tractor supplies. However, I would think it would have to be extremely low to give you the symptoms you describe. It's also possible that the clutch is slipping badly. If the FD is seriously low you probably have a bad bellows seal and the oil may have gotten into the clutch disc.
  12. Have you done work on the ignition system recently? Bogging down at a certain RPM regardless of load sounds like an issue a few of us have experienced with points bounce from not having the spring attached properly.
  13. That’s pretty much what I used. It chipped a little bit of the plastic off of the hub, but it isn’t noticeable after I cleaned and painted the wheel. Be sure to leave the nut on, but loose. Best to thread it off until it is flush with the end of the steering shaft/tube. You’ll also want to have something solid on top of the tube to press against so as not to damage the top of the steering shaft/tube.
  14. The Gilmore is an awesome place. The WPC Club meet had their car show there one year. I think I enjoyed the museum more than the car show, and the car show was good too.
  15. Yes, vehicle refinement has come a long way in 70+ years, but I still enjoy driving mine around. It has it's own charms. Nice lookin' truck.
  16. There should not be any continuity between the coil output lead (high tension terminal) and the + or - terminals. You should get a little over 1 Ohm between the + and -. To check the secondary winding check from the output terminal to the coil case.
  17. You may have a coil that is failing when it heats up.
  18. It could have been part of an aftermarket water injection system. I've never seen one, but I've heard that they were often used 'back in the day'. The theory is that the water mist that was introduced into the intake air/fuel charge helped to cool the combustion temps to reduce detonation.
  19. You may need to remove the return line and fitting to be able to inspect them properly. If it has been cross threaded, as suggested earlier, you will likely need to replace the fitting and/or make a new line. It's just a piece of brake line that can be bent and flared as needed. Also, regarding the oil pressure relief valve. It actually blocks the return flow from the filter when the oil pressure is low. This stops oil from flowing through the filter to ensure the critical engine components receive oil first. The filter is fed directly from the oil pressure galley.
  20. Your slight voltage drop through the coil is due to the fact that something in your distributor is consuming a small amount of current. What may be happening is that your points are burnt due to the higher voltage while running. This can cause a high resistance so that they won't make a good ground connection. As Sniper stated, if the points are closed they should be providing a ground to the coil to complete the electrical circuit. This would be indicated by a 0 volt reading. The fact that you are getting 5 volts out with 8.4 in tells me that you have a complete circuit, but with another load in the circuit. That load could very well be fouled points contacts. Try cleaning, or replacing, the points and recheck your voltages. I also agree that you need to revisit your starter solenoid connection. It should only provide 12 volts during cranking. If it is feeding a continuous 12v while running that can lead to premature points failure, as you may be experiencing.
  21. To pull the axle shaft you need to rig up a puller or use a slide hammer. It is held in by the outer bearing cup pressed into the axle tube. When you reassemble, with grease packed bearings, you’ll need to shim both sides simultaneously to achieve the proper end play/preload for the bearings. You can’t do them one side at a time. The axle shafts press against a floating block in the center of the diff. The brake backing plate presses the bearing cup into the axle tube, thus pushing the axle shaft against the block. If you don’t work with both sides equally you’ll end up with the axles off center.
