I’m anxious to diagnose the issue with the Scout, because I want to know what ‘s wrong but also because I want to drive her. I went out after dinner Monday night to check the timing to see if it was advanced or retarded, which could be the cause of my mystery sound. I had an old yard sale Sears timing gun that I hooked up to the battery and #8 wire (Scouts use the #8 wire instead of the more commonly used #1 wire on most GM/Ford products) but I got no light from the gun at all. On the bench I broke it down to reveal old capacitors and components that had probably fizzled out during the first Bush administration, so I hit the Harbor Freight for a new unit.
Back under the hood I cleaned off the timing marks and chalked the pulley. When I set the gun to 0˚ and ran it, the chalk hit at about the 15˚ mark—but I hadn’t run the engine or disconnected the vacuum advance yet, which meant the reading wasn’t entirely correct. It was getting dark by this point so I shut her down and put her back in the garage to avoid the rain forecast for the evening.
Thursday evening I went back outside to give it a second go; this time I was able to plug off the vacuum advance and get things ready for a proper diagnosis. While I was getting a wrench on the hold-down bolt, I was holding the distributor body and it spun under my hand with a little bit of pressure—which told me it wasn’t tight for a while. When I put the gun on it, the chalk showed up at about 15˚advanced, so I spun it back to 5˚ and listened to the idle settle down.
Tightening that off, I noticed some smoke coming off the manifold on the passenger side, which makes me wonder if there’s a leak between the manifold and the block. I’ve been smelling something from the engine for a while, and I wonder if that could be the culprit—it would certainly explain the additional noise.
Meanwhile, my oil sample is safely in the hands of Blackstone as per the USPS’s tracking service. Going on past experience, it’ll take 2 weeks or so to hear back from them on what the oil can tell us. I’ve got a new Fuel-Pro gasket sitting behind my desk for the next major step: dropping the pan to see if there are any chunky bits at the bottom.
While I had the timing gun out, I figured I’d throw it on the Travelall for giggles to see what the timing looked like there. I’d solved the high idle issue I had before by re-connecting the PCV valve on the back of the valley pan, but because I’d cranked all of the idle screws in all the way, I had to spin them back out. The engine is running sloppily now, loping around like it’s not firing correctly, and the exhaust is abhorrent—the girls flipped out because it quickly filled the house. I’ve got to get this thing mobile quickly so I can move it away from the windows to properly work on it. In any case I couldn’t get a good enough look at the chalk before I was forced to shut her down. New PCV valves from that era are hard to find, but I think a new one will help out immensely.
While I was digging around in my parts bins I pulled the two mirrors out and mocked them up on the side of the truck. They look great! I’ve got to go back through my reference photos from Nats and see how other owners mounted the top mounts to their doors; I’ve got a very small vertical area to work with and I’d prefer not to mess up the mounting surface for the weatherstripping, which may be my only option.
At the bottom the two holes pre-drilled for the old mount aren’t wide enough for this setup; I can easily drill a new hole and add a backing nut inside the door. I think what I might do is (with my new fancy welder) cut a small thin plate, weld two shallow bolts to that, drill holes through the door, and feed the bolts through the holes so it’s as flat as possible.
Another thing I noticed was that there are three dimples in the passenger side windshield frame for where a sun visor would have been mounted; I think this thing was as stripped-down as possible when it left the factory.
I’m talking to a guy from the Binder Planet who offered up a rear Travelall seat back in February, and who has some other assorted barn door parts left from a project. He’s able to meet in Rhode Island, so I think my plan is to rent a pickup and drive up there over a weekend, stay the night somewhere local, pick up the parts, and drive back the following day. If I time it right I might detour up to Mahopac to say hi to some high school friends on my way back home.
