I have a 2002 Silverado with 172k miles, 5.3L, 4L60E, LS trim, a little rust but it's fixable. Located north of Kansas City, Blue Book is...
Solved! Finally got it straightened out. Nate, you're the man, the valves were all screwed up. Got the book out and bought myself a feeler...
Just to tie up a loose end, this was solved in conjunction with my dead cylinder issue here: https://talk.classicparts.com/showthread.php?t=8981
I'm going to follow this up on the "Dead cylinders?" thread, as the two problems seem to be related.
I was just about to post that I do hear a slapping noise coming from under the valve cover. I took the cover off to set the timing manually and...
Okay, I got the timing set by hand. It's probably not perfect, but I believe it's close enough that it should run pretty smoothly as long as...
Just to be clear, where is the #1 cylinder on the motor? On the front, near the radiator or on the back, near the firewall?
Ok, installed the new vacuum advance mechanism and same result. At fast idle or above, the distributor jumps back and forth. At slow idle or if...
I'll give this a try tonight...hopefully that's all it is. The cap, rotor points and condenser look new, so I'm hoping the PO just installed them...
Earlier this Spring I restored a 1968 M715 Kaiser Jeep 5/4 ton pickup. Awesome project, ton of fun. Very cool truck, but I ended up selling it...
Yeah, it's connected to the carb, I misspoke. I bought the new mechanism from Classic Parts today, so I'll try it out tonight and see what happens.
That could be, but I think it's a faulty vacuum advance. I will replace it tonight and see. The distributor doesn't wobble at idle or when I...
Yep, I've got all three of those books already. Very handy, but I couldn't find the shift pattern in them. I'm somewhat familiar with the SM420,...
I'm pretty sure the firing order is right. The wire's are in the correct order on the cap, but maybe not at the right starting point. I'll check...
Yep, I'm the one with the dist. doing the jig, but it doesn't move at idle, so I figured that wasn't bothering it. Also, I unplugged the vacuum...
Ok, I'm still working on smoothing this thing out. '54 3600 with a '55 235 with automatic choke. I'm getting spark to all cylinders, carb is...
Another thing occurred to me, what if the mechanism is fine, but I'm not getting enough vacuum from the manifold? I don't have a pressure guage...
Oh, almost forgot, yes it's a 4 speed. A nice surprise as I believe this was an option (not standard) in 1954 even on the 3/4 ton, right? I...
Well, I introduced myself here (including pics): https://talk.classicparts.com/showthread.php?t=8954 First name's Clayton and I live in...
Yeah, it's wagging back and forth, that ain't right. As I understand it, the distributor should twist along the arc as vacuum increases (i.e....
