I'm Awesome
Well, no phone call today, although I had to go by that shop today and saw that it's on the lift. I hope for good news sometime tomorrow.

First Guess: Incorrectly adjusted tie rod sleeves, probably caused by a failure to center the steering gear before dicking with the toe. LOOK at the tie rods and sleeves to see if they're reasonably even side-to-side. If they're not...take the truck back to them.They did the wheel alignment, and it drives MUCH straighter, but it can't turn left. To get through a left hand turn, I have to go halfway through the turn, back up (while turning right), and go through the turn again.
"Backfire" into the intake manifold, or "backfire" in the exhaust. Big difference.When I went to go pick it up from the inspection station, is started RIGHT up. It ran a little sluggish and still had no real power... ...I FLOORED it. The engine fell flat on it's face and stalled out. I got it restarted, but barely made it up the hill. It nearly stalled out twice more on the way home and has near zero power. Then, I got a backfire at WOT.
MAYBE this is due to the way the engine was assembled. I'd want a compression test of all eight, to verify evenness but also to verify reasonably normal compression pressure which is a quick 'n' dirty way to verify reasonably normal cam timing.This, my GMT400 listeners, is the advantage of building an engine yourself as opposed to buying one out of the box.
Possible. Not enormously common on TBI, though. You do have the plug wires for #5 and #7 well-separated...right?1. One of the cylinders isn't getting spark for whatever reason (because to backfire like that, it HAS to have fuel).
Sadly, also possible.2. Something messed up in the valve train again (betting EFFING not have!)
I get my ignition modules at the Treasure Yard--usually but not always OEM and top-quality, and pennies on the dollar.3. The reviews on Summit Racing, for the new distributor I bought, said REPLACE the ignition control module that the distributor comes with, with an AC Delco or Screaming Demon ICM. The one it comes with just causes problems.
Not at all likely. Closer to IMpossible.4. The oil pressure sending unit may be causing problems other than erratic oil pressure readings.
A good attitude is a fine tool in itself. When the good attitude isn't getting the job done, flinging tools and harsh language often works wonders.any work I do on the RCSB will be outside. That's not such a bad thing sometimes. More room, occasional sunshine, less chance of thrown tools hitting something, etc.
Will do.It's probably something simple causing the engine to not run right. Stay tuned.
Given symptoms, ignition timing, fuel pressure, compression from rocker arm adjustment. Too tight on a rocker arm will not make noise but will hang the valve open effectively killing that cylinders compression and power. Lack od spark on one cylinder would about have to be a bad cap, wire or broken/defective plug.Unbelievably, the scrap pile passed inspection! . The guy that did the inspection said it looks in damn good shape for it's age.
Now the bad news. They did the wheel alignment, and it drives MUCH straighter, but it can't turn left. To get through a left hand turn, I have to go halfway through the turn, back up (while turning right), and go through the turn again.
For a right hand turn, however, I can make a hair pin turn. The truck did not have this problem before I tore into the steering. I'm guessing that the Pitman arm isn't installed on center.
Now more kinda bad news. When I went to go pick it up from the inspection station, is started RIGHT up. It ran a little sluggish and still had no real power. Then, I had to go uphill and there was one of Brandons Kids (an illegal immigrant driving less than half the speed limit) in front of me, so I FLOORED it. The engine fell flat on it's face and stalled out. I got it restarted, but barely made it up the hill. It nearly stalled out twice more on the way home and has near zero power. Then, I got a backfire at WOT.
This, my GMT400 listeners, is the advantage of building an engine yourself as opposed to buying one out of the box. I now have a couple working theories as to why this is happening, instead of sitting there staring at the engine like a deer in headlights, wondering what the problem could be.
1. One of the cylinders isn't getting spark for whatever reason (because to backfire like that, it HAS to have fuel).
2. Something messed up in the valve train again (betting EFFING not have!)
3. The reviews on Summit Racing, for the new distributor I bought, said REPLACE the ignition control module that the distributor comes with, with an AC Delco or Screaming Demon ICM. The one it comes with just causes problems.
4. The oil pressure sending unit may be causing problems other than erratic oil pressure readings.
The only part that sucks about this now is that the Wife's Buick is the current resident in the garage. It's not leaving there until she drives it out under it's own power. That means any work I do on the RCSB will be outside. That's not such a bad thing sometimes. More room, occasional sunshine, less chance of thrown tools hitting something, etc...
But it now has a sticker! Two, actually! So, the most difficult part is over.
It's probably something simple causing the engine to not run right. Stay tuned.
Take it back and bunch someone in the dick. Regardless of who’s/what’s at fault for the misalignment, it should have never left their shop.Now the bad news. They did the wheel alignment, and it drives MUCH straighter, but it can't turn left. To get through a left hand turn, I have to go halfway through the turn, back up (while turning right), and go through the turn again.
Either way, this should have been caught by the alignment tech during his test-drive if not during the vehicle set-up on the alignment rack.

I also apologize. I understand now. Don’t punch people in the dick.My apologies. I think there's been a serious miscommunication, here.
The truck drove straight and turned normally BEFORE I put on all the new steering components. After I replaced everything under the sun, THAT'S when the turning issued started. While an alignment fixed the problem with the steering wheel being upside down and the front tires fighting each other, it didn't fix the turning problem.
I think, from the way I worded it before, may have sounded like the alignment shop caused the turning problem.
Maybe not punch them but they certainly should have noticed the lack of turning radius during the test drive and noted it. Upon returning from said drive, they should have brought it to your attention and offered diagnosis/corrective measures.My apologies. I think there's been a serious miscommunication, here.
