Geeze... I feel for ya, man. I was simply happy to drive my Cherokee around today.
You read it. You can't unread it!
1978 Cherokee Chief - bought for parts, and sold as a runner
k, i checked a few things, then did some quick work.
My fuel system is currently closed, non vented, because of the PO removing the stock gas tank which had all the venting stuff. It used to just vent inside the truck by having the fill tube and breather disconnected, so it all just let vapor into the rear fender well. I sealed it up and put on a vented gas cap, but in the vegas heat it would always bloat the tank and whatnot.
I just hooked up all the venting system to the closed tank in a kinda ghetto way. I took the two vent tubes from the original gas tank, and stuck them into two holes i drilled in the breather tube. I dont see how this would be any different than venting from the top of the stock tank. The gas expands, vapor rises up the filler neck/breather tube, and it SHOULD be able to vent though the check valve in the fender, then be sucked from there up into the vapor canister under my hood, and then through the vacuum port at the brake booster.
After driving it yesterday, it was spilling vented gas vapor down the side of the truck, out from the gas cap. That didnt happen today, but then again it didnt sit in the sun all day.
this issue could also be exacerbated by the fact that my exhaust dumps under the truck now, and could be heating up the tank as I drive maybe?
Anyway, i hooked it up as so, for the time being, to see if it helps. I figure excess pressure in the tank cant be a good thing, and this system should also allow it to breath while sucking in gas, correct?
Dunno if that'll help the situation at all, but it should help the truck overall.
I took it for a drive today with an added ground, the moved fuel lines (one was real close to the valve cover, as mentioned, and the one under the fuel pump was touching up against the lower rad hose, so that wasnt good im sure).
I drove it for a good hour I'd say, in the setting sun, at about 95-98 degrees outside, truck was running at the same temp, and it ran great? Only thing i can think is that it wasnt sitting in the sun all day, and wasnt in the direct sun while driving for most of the time. I'll take it out in the heat tomorrow and we'll see whats up.
Well, been driving it for the past few days, most everything seems okay. Not entirely sure though.
It seems to be shifting a bit high, but i can fix that, maybe the vacuum modulator needs adjustment.
Also, i seem to have some devent driveline vibration any time i rev up the engine, in neutral or when im driving. Nothing insane, but i can feel the truck vibrate a bit. Looking under it while it's running, it almost looks like the torque converter is wobbling a bit, but im not sure. It definitely didnt feel like this in the past.
Well, it's been almost 11 months since I picked up the beast, so I figured it's time for a little then vs. now...
I've come quite a ways, it seems, even though at times it felt like i was pedaling backwards.
Then....the day I bought it...
Sigh, I'm starting to realize how many hours and dollars I've put into this truck, not to mention how many bumps, bruises, cuts, curse words, and whatnot as well...but I suppose there have been smiles as well.
Transmission shop will be getting a call tomorrow, considering they lost half my bushing.
Apparently the torque arm bushing is fairly important. I was reading that in 4lo, 1st gear, the 360 and transmission will produce about 3000 ft. lbs of torque....sooooo....i'd say it's fairly necessary to get that bushing back on there.
