86-350-460-dually Posted April 29, 2019 Author Share Posted April 29, 2019 I should have also said that I believe you've found the problem. Your fuel gauge is reading much higher than it should and your temp gauge is reading much higher than it should. They are run by a common culprit that is known to cause that problem. Thank you. My buddy also wanted me to point out that he believes he saw a faint blue in the white smoke from the exhaust. Link to comment Share on other sites More sharing options...
BullnoseHunter02 Posted April 30, 2019 Share Posted April 30, 2019 Thank you. My buddy also wanted me to point out that he believes he saw a faint blue in the white smoke from the exhaust. I think a little blue smoke is normal. White usually means oil got in the combustion chamber, if you cant end up figuring out the issue, i might take it in to get checked out. Oil can be destructive if it gets in the wrong spots! Good luck. Hope i was able to help! Link to comment Share on other sites More sharing options...
ArdWrknTrk Posted April 30, 2019 Share Posted April 30, 2019 All sorts of questions to ask/answer. First, do your fuel gauge and oil pressure gauge appear to be reading normally? I ask because they and the temp gauge are run by the Instrument Cluster Voltage Regulator, which is a real silly little circuit. If it goes bonkers, and they do, then all three gauges go wonky - together. As for measuring the temp manually, do that on the side of the thermostat housing, or the upper radiator hose after the thermostat opens. And this page from Mobil does a good job of describing a leak-down test. As for what tool to buy, I made my own so don't have experience with any one tool. However, whatever tool you get should have two gauges, one before and one after the orifice. And, it should have several spark plug adapters so it'll fit several engines. Plus, a pressure regulator as part of the kit is particularly helpful as you frequently have to adjust the pressure for each cylinder because of more or less leakage that changes in the high-side pressure due to flow. My procedure is to bring the cylinder up on TDC, screw the plug adapter in, adjust the regulator to 100 psi so that you have a constant reference, and then read the low-side gauge. An 80 psi reading means you have 20% leakage, which is bad. So now you go listen to the intake and exhaust to check for valve leaks and dip stick tube for ring leakage, and then check the radiator for head gasket leakage or cracked heads. Oh - also put a hose in the spark plug hole of adjacent cylinders and put the other end to your ear. Head gasket leaks can frequently go into the adjacent cylinder. That's a very good description Gary. One thing I would add is to start with the radiator cap *off*. Suddenly pressurizing your cooling system to 100psi can cause trouble with heater core, hoses, freeze plugs, etc... Yeah, the cap *should* release but why take the chance? If one has a regulated source of air leak down testers may be available to "rent" from the bigger parts stores. A cooling system pressure tester is also available. I don't know of any places that have the reagent to test antifreeze for combustion byproduct. Link to comment Share on other sites More sharing options...

Good luck. Hope i was able to help! Unfortunately there is a major knocking sound that came up last night. It's pretty bad. I do have video of it with audio. I will try and see if I can post it here. I am moving in 6 days and this is not exactly the sound that I wanted to be hearing right now or the smoke that I wanted to be seeing. Haha. I tried to save a bullnose, but unfortunately, I dont have the means to haul this thing 650 miles with me. I may have ended the life of another bullnose, sadly. Link to comment Share on other sites More sharing options...

I'm sorry you've put so much effort into this only to have it go bad at the last moment. I know I could swap the engine in a long day, with a jack, hoist, my toolbox and a hand with a few things like the hood. If the other engine you spoke of is still available maybe it's an option? But I don't know if that's an option for you at this point, or how you intend to get your tiny home moved without the tow rig. Link to comment Share on other sites More sharing options...

That 460 motor is still available and we have a hoist and my neighbor literally pulls engines all day at a junk yard, so im sure it can be done, however I don't have the time to do it this week, of all weeks haha. Interesting side note though, that 460 motor in the RV has an interesting set up. It runs off of gas or propane. I just don't have the time to do the swap.

Im sure that truck can be saved, realistically, having someone look at it might not be the worst idea. After you move that is. Moves can be busy and stressful, good luck!

I just wanted to say thanks to everyone who has helped me out! I am no longer a member of the bullnose community, as of about an hour ago, however I wanted to honestly thank everyone! You guys have taught me a ton as it was my first project vehicle ever and first time dabbling into how everything works. I learned a ton and will take all of this with me to California and work on something new there. Thanks again everyone! I wish you all the best with your bullnoses!

Thank you Adam, for reaching out to our little community. Must be disheartening for you this late in the game but hopefully someone else can make good use of that tow rig. If not repowered, then as valuable parts to keep their own classic truck going Gary does this all on his own and really strives to be the best source of documentation and knowledge about these vehicles available. Wish you a safe trip and a great future in California. ,Jim Link to comment Share on other sites More sharing options...
