Not much progress to report today – I worked all day on it and accomplished very little!
I got started with adjusting the valves. The intake valve cover came off easily, but as I thought, the side valve cover fought me! I don’t think it has been off in a LONG time! I removed the bell, fording valve and PCV valve – what a PITA! Like I said, this stuff hasn’t been apart in a LONG time! I cleaned them up with the wire wheel, then threw them in a container with gas to soak a little while. After they soaked and got some of the caked up oil out, I threw them in the ultrasonic cleaner for about 10 minutes to get ALL of the old oil out. Then I reassembled. Turned out nice and clean!
It was leaking oil, and after I finally got the cover off I saw why – the cork gasket was hard and brittle. Once both valve covers were off, I adjusted the valves – most of them were too tight. I used the leftover weather strip glue to attach the new gasket to the side of the block and let that set up while I cleaned and repainted all of the attaching hardware and throttle linkage.
While that was drying, I scuffed and painted my last 2 wheels with 24087 for the spare tire on my other Jeep and the M100 trailer.
Then I removed the old pedal draft pad (there was only one installed) and installed the new ones. I also reinstalled the master cylinder floor plate.
Then the fun began! After the side cover was dry, I put a little RTV on the outside of the side cover gasket and bell hole, then reinstalled the cover. Getting the bell, fording valve and PCV valve all tight and lined up was a PITA! I reinstalled the linkage with new washers and cotter pins. While I was in the area, I removed the flex hose, installed a nipple in the fuel pump and installed a rubber hose with clamps.
When I started the engine, it ran like crap! You could hear a fairly loud hissing noise, which after closer inspection turned out to be a vacuum leak – or should I say LEAKS! BOTH of the elbows on the vacuum side (bottom) of the pump were loose AND the fording valve/PCV valve weren’t tight enough! I put a wrench on the fording valve and turned it a good 4-5 turns which resulted in the PCV valve UNSCREWING from the tee on the line. I had to break the tee loose from the line (again, this stuff hasn’t been loosened in YEARS) in order to tighten it on the PCV valve nipple, then reattach the hard lines. I removed the hard lines from the elbows on the pump, wrapped them with Teflon tape, reinstalled them and the hard lines – vacuum leaks sorted! I cranked it up and it idled very well! I took it for a drive and once it warmed up – same thing – cutting out and trying to cut off.
I took a break from the mechanical part and decided to touch up the hood numbers. I sprayed some 24052 in a cap and used a brush to fix the bleed through. It turned out OK, but you can see it if you look closely.
Back to the mechanical stuff. I had a few more minutes to work on it, so I decided to put the original distributor back in (the one with the breakerless ignition). Once I did that, I cranked it up and adjusted the timing. I adjusted the air gap on the electronic pickup and installed the adapter to hook up the dwell meter to the distributor. I fired it back up and checked the dwell – 30deg. It is SUPPOSED to be around 45!? I adjusted the idle to 700rpm and the carb until it ran decent. I took it for a test drive and drove around the field for a while. It ran great as long as I kept the RPMs up – ran like crap closer to idle. Once back in the shop, it idled great!??? I gave up for the day!
